U-1(g) U-1(g)(1) Unfired steam boilers shall be constructed in accordance with the rules of Section I or this Division [see UG-125(b) and UW-2(c)].

U-1(g)(2)The following pressure vessels in which steam is generated shall not be considered as unfired steam

boilers[不能被认为是非火焰直接加热蒸汽锅炉], and[并且] shall be constructed in accordance with the rules of this

Division:

(a) vessels known as evaporators or heat exchangers;

(b) vessels in which steam is generated by the use of heat resulting from operation of a processing system

containing a number of pressure vessels such as used in the manufacture of chemical and petroleum

products;

Table U-3 Added ISO-148(Part 1, 2, & 3) to Table U-3 [在表U-3中增加ISO-148(第1, 2和3部分)]

Charpy Pendulum Impact Test Part 1: Test Method, ISO 148-1: 2006 [Charpy摆锤冲击试验,第一部分:试验

Pieces for Verification of Test Machines: ISO-148-3: 2006 [Charpy摆锤冲击试验,第三部分: 用于试验机验证

的Charpy-V 试验方法试样的制备和特征, ISO 148-3:2006]UG-84(b)(1) is revised to add ISO-148 (Parts 1, 2 & 3) as acceptable for impact test procedures and apparatus in addition to SA-370.

It was discovered that there are virtually no ASTM strikers available for use throughout Europe, Asia or Australia. It was also learned that the ISO striker profile has no real effect on absorbed energy values up to 74 ft-lbs. In materials with toughness in excess of 75 ft-lbs, the ISO striker is slightly more conservative and will produce absorbed energy values that are slightly lower than those obtained using the ASTM striker. Lateral expansion values will vary no more than .001 inch when based on acceptance criteria of .015 inch lateral expansion. Based upon these facts it is proposed that impact testing in accordance with ISO-148 also be permitted in UG-84(b)(1).

[UG-84(b)(1)已经修改,除了SA-370以外,对于冲击试验的程序和设备,允许采用ISO-148(第1, 2和3部分)标准.]

UG-11(c) (5) UG-11(c)(5) added under UG-11(c) “Welded Standard Pressure Parts for Use Other Than the Shell or Heads of a Vessel." [在UG-11(C)下增加UG-11(C)(5) ”除容器筒体或封头以外的标准焊接承压件”]

(5) The Manufacturer of the vessel to be marked with the Code Symbol shall be satisfied that the parts are

suitable for the design conditions specified for the complete vessel in accordance with the rules of this

Division and that the requirements of (1), (2), (3) and (4) above have been met for each welded standard

pressure part.

[负责打容器规范钢印的制造厂应该获得确认,即这些零件适合符合本规范要求的容器设计要求, 并且上述(1),(2),(3)

和(4)的要求也得到满足.] The addition of UG-11(c)(5) is proposed to address a concern that the vessel Manufacturer needs to verify that welded standard pressure parts comply with the rules of this Division. Similar words are already provided at the end of UG-11(a) and UG-11(b).

与UG-11(a), UG-11(b)最后部分的叙述相一致,即容器制造厂要验证标准焊接承压件符合规范的要求.

UG-14(b),(b) Except for flanges of all types, hollow cylindrically-shaped parts [up to and including NPS 4 (DN l00)] may be machined from rolled or forged bar,[用轧制或锻制的棒料机加工] provided that the axial length of the part is

approximately parallel to the metal flow lines of the stock. Other parts, such as heads or caps [up to and including

NPS 4 (DN 100)], not including flanges, may be machined from rolled or forged bar.[可以用轧制或锻制的棒料机加

工]Elbows, return bends, tees, and header tees shall not be machined directly from barstock.This change would make UG-14(b) consistent with UG-14(a), SA-182 A06 5.4 and 6.5; SA-403 A06 4.1, 5.12 and 6.4, and Code Case 2148, which do not have any requirement for “hot-rolled bar” and would permit other cold-rolled bar.

Annul Code Case 2148 six months after publication of the changes

与UG-14(a)保持一致, 不要求”热轧棒料”.

Explanation

解释

UG-35.2(d)UG-35.2(d)(1)Quick-actuating closures that are held in position by a locking mechanism designed for manual operation shall be designed such that if an attempt is made to open the closure when the vessel is under

pressure, the closure will leak prior to full disengagement of the locking components and release of the

closure. The design of the closure and vessel shall be such that any leakage shall be directed away from the

normal position of the operator.

(中文翻译略) It has been pointed out the paragraph UG-35.2(d)(1) can misinterpreted to require a closure to leak when the locking mechanisms are still fully engaged. This is not the intent of this paragraph. The paragraph is intended to make sure that if someone ties to open a closure which is under pressure that it will leak before the locking mechanism is fully disengaged and the closure is released. The re-wording clarifies this design requirement. In addition was pointed out that the designer of the closure may not know the location of the operator since he may not be the designer of the vessel or system. The re-wording clarifies this requirement

UG-36(b)(1)UG-36 Openings in Pressure Vessels

…

(b) Size of Openings

(1) Properly reinforced openings in cylindrical and conical[锥型]shells are not limited as to size except with the

following provisions for design. The rules in UG-36 through UG-43 apply to openings not exceeding the following: for

vessels 60 in. (1500 mm) inside diameter and less, one-half the vessel diameter, but not to exceed 20 in. (500 mm);

for vessels over 60 in. (1500 mm) inside diameter, one-third the vessel diameter, but not to exceed 40 in. (1000 mm).

(For conical shells, the inside diameter as used above is the cone diameter at the center of the opening) [(对

于锥型筒体, 上述所指的内径是开孔中心处的锥体直径)]. For openings exceeding these limits, supplemental rules of

1-7 shall be satisfied in addition to UG-36 through UG-43. Alternatively, openings in cylindrical or conical shells

exceeding these limits may be designed for internal pressure using the rules of 1-10 in lieu of those given in

1-7(a) and / or 1-7(b).[作为另外一种方法,在圆筒体或锥形壳体上的超过这些限制的开孔也可以以内压按照附录1-10

的规定来设计,而不必按照附录1-7(a) 和/或 1-7(b).]Added new appendix 1-10 for alternative method for design of large openings and revised UG-36(b)(1) to refer to it.

Clarified that cones are also included in the reinforcement design rules in these sections. A note is also added to Appendix 1-7(b)(1) limiting application of the 1-7(b) rules to cones with a half apex angle not exceeding 30 degrees

澄清了补强设计也适用于锥体. 在附录1-7(b)(1)中增加了一个注解以说明附录1-7(b)的规定仅适用于锥体半顶角不超过30度的情形.

新增加了用于大开孔设计的另一方法附录1-10.

UG-37UG-37(h) added under UG-37 REINFORCEMENT REQUIRED FOR OPENINGS IN SHELLS AND FORMED HEADS [新增UG-37(h)]

(h) The reinforcement rules in this Division are applicable for internal or external pressure and do not

address the requirements for openings under the action of externally applied loadings (such as pipe

reactions). When externally applied loadings are to be considered, see U-2(g).

[(h)本规范的规定适用于内压或外压,并没有规定适用于承受外部栽荷的开孔的要求(外部载荷指例如管子反作用力).如

果考虑外部栽荷,参见U-2(g)] The reinforcement rules in Section VIII Division 1 are applicable for internal or external pressure and do not address the requirements for openings under the action of externally applied loadings (such as pipe reactions). This item was proposed because of several requests for interpretation that asked what opening reinforcement rules were applicable under loads other than pressure. This proposed action does not change any Code requirements, it merely provides information that may useful to the designer.

澄清本规范的开孔补强规定适用于内压或外压,不适用于承受外部栽荷的情形.

UG-37 Text in UG-37(a) revised:

UG-37 REINFORCEMENT REQUIRED FOR OPENINGS IN SHELLS AND FORMED HEADS

(a) Nomenclature. The symbols used in this paragraph are defined as follows:

…The reinforcement rules of UG-37(a) are not clearly defined for the case of ERW or autogenously welded pipe or tube. The definition of “tr” in UG-37(a) implies that the seamless allowable stress values should be used in the calculation of

Explanation

解释

E = 1 (see definitions for t r and t r n)

E 1 = 1 when an opening is in the solid plate or in a Category B butt joint; or

= 0.85 when an opening is located in an ERW or autogenously welded pipe or tube. If the ERW or autogenously welded joint is clearly identifiable and it can be shown that the opening does not pass thru this weld joint, then E 1 may be determined as using the other rules of this paragraph; or

[=0.85, 当一个开孔位于一个ERW 或自身焊接管时. 如果ERW 或自身焊接管接头清晰可见并且可以看到开孔并非通过该焊接接头时, 则E1可以以本段其它规则来确定,或]

= joint efficiency obtained from Table UW-12 when any part of the opening passes through any other welded joint …

the required thickness “tr”, even though the shell is constructed of ERW or autogenously welded pipe or tube. Past Interpretations VIII-1-92-25R and VIII-1-98-12 also support the use of seamless allowable stresses for the calculation of “tr” in ERW or autogenously welded pipe or tube.

The proposed changes require that “E1” is taken as 0.85 for all shells constructed of ERW or autogenously welded pipe or tube, unless it can be shown that no part of the opening passes thru the ERW or autogenously welded joint. In the case where the ERW joint is readily identifiable and it can be shown that the opening does not pass thru the ERW weld joint, then “E1” may be determined using the other definitions of “E1” given in paragraph UG-37(a).

UG-42(a)(2), (c) & (e),

UG-42 REINFORCEMENT OF MULTIPLE OPENINGS

a) (See UG-39 for multiple openings in flat heads.) (a) When any two openings are spaced at less than two times their average diameter, so that their limits of reinforcement overlap [see Fig. UG-42 sketch (a)], the two openings shall be reinforced in the plane connecting the centers, in accordance with the rules of UG-37, UG-38, UG-40, and UG-41 with a combined reinforcement that has an area not less than the sum of the areas required for each opening. No portion of the cross section is to be considered as applying to more than one opening, nor to be considered more than once in a combined area

(1) The available area of the head or shell between openings having an overlap area shall be proportioned between the two openings by the ratio of their diameters.

(2) For cylinders and cones [对于圆筒和锥体] if the area of reinforcement between the two openings is less than 50% of the total required for the two openings, the supplemental rules of 1-7(a) and (c) shall be used. (3) A series of openings all……..

c) Alternatively, any number of adjacent openings, in any arrangement, may be reinforced by using an assumed opening enclosing all such openings. The limits for reinforcement of the assumed opening shall be those given in UG-40(b)(1) and (c)(1). The nozzle walls of the actual openings shall not be considered to have reinforcing value. For cylinders and cones [对于圆筒和锥体] when the diameter of the assumed opening exceeds the limits in UG-36(b)(1), the supplemental rules of 1-7(a) and (c) shall also be used.

e) When a series of two or more openings in a cylindrical or conical [或锥体] shell are arranged in a regular pattern, reinforcement of the openings may be provided per the rules of ligaments in UG-53. This item was established to make revisions to UG-36, UG-42 and Appendix 1-7 clarifying that cones are also included in the reinforcement design rules in these sections. A note is also added to Appendix 1-7(b)(1) limiting application of the 1-7(b) rules to cones with a half apex angle not exceeding 30 degrees

UG-84(b)(1). UG-84 CHARPY IMPACT TESTS UG-84(a) General. Charpy V-notch [V 型缺口] impact tests in accordance with the provisions of this paragraph shall

be made on weldments and all materials for shells, heads, nozzles and other vessel parts subject to stress due to pressure for which impact tests are required by the rules in Subsection C.

UG-84(b)(1) Impact test procedures and apparatus shall conform to the applicable paragraphs of SA-370 or ISO-148 (Parts 1, 2 and 3) [或ISO-148 (第1, 2 和 3部分)] ISO-148 allows the usage of both Charpy V-notch and U-notch testing. Inclusion of ISO-148 into the code will require the words "V-notch" be added to UG-84(a) to ensure that Charpy V-notch testing is used exclusively.

Include ISO-148 (Parts 1, 2 & 3) for CVN testing procedures & apparatus (ISO Striker). A recent incident has led to the discovery that the impact testing apparatus used throughout

修改内容

Explanation

解释

most of the industrial world (Europe, Asia & Australia) is not in

compliance with SA-370/ASTM E23 because the Striker

profile on the ISO machine has a different profile than the

profile designated by ASTM. Outside the USA most

companies and testing laboratories are using the ISO impact

testing apparatus in accordance with ISO-148 Therefore, any

impact testing that is performed outside the USA cannot be in

strict accordance with UG-84 as it is currently written. It was

discovered that there are virtually no ASTM strikers available

for use throughout Europe, Asia or Australia. It was also

learned that the ISO striker profile has no real effect on

absorbed energy values up to 74 ft-lbs. In materials with

toughness in excess of 75 ft-lbs, the ISO striker is slightly

more conservative and will produce absorbed energy values

that are slightly lower than those obtained using the ASTM

striker. Lateral expansion values will vary no more than .001

inch when based on acceptance criteria of .015 inch lateral

expansion. Based upon these facts it is proposed that impact

testing in accordance with ISO-148 also be permitted in

UG-84(b)(1).

除了SA-370以外,对于冲击试验的程序和设备,允许采用

ISO-148(第1, 2和3部分)标准.但因为ISO-148还包括了U型

缺口的冲击试验,所以在UG-84要规定V型缺口.

UG-90(b)(19) UG-90 GENERAL

(b) The Manufacturer has the responsibility of assuring that the quality control, the detailed examinations, and the

tests required by this Division are performed. The Manufacturer shall perform his specified duties. See UG-92 and

10-15. Some, but not all, of these responsibilities, which are defined in the applicable rules, are summarized as

follows:

…

(19) providing for retention of radiographs (UW-51), ultrasonic test reports (12-4), and Manufacturer’s Data

Reports (UG-120),and other documents as required by this Division (10-13). [和本规范附录10-13规定的其它文

UG-117(f); UG-117 CERTIFICATES OF AUTHORIZATION AND CODE SYMBOL STAMPS

UG-117(f) Evaluation for Authorization and Reauthorization. Before issuance or triennial renewal of a Certificate of

Authorization for use of the U or UM Stamp, the Manufacturer’s facilities and organization are subject to a joint review

by a representative of his inspection agency and an individual certified as an ASME Designee who is selected by the

concerned legal jurisdiction. A written description or checklist of the Quality Control System which identifies what

documents and what procedures the Manufacturer will use to produce a Code item shall be available for review.

A written report to the Society shall be made jointly by the ASME Designee and the Inspection Agency employed by

the Manufacturer to do his Code inspection. This report is then reviewed by the Subcommittee on Boiler and Pressure

Vessel Accreditation, which will either issue a Certificate of Authorization or notify the applicant of deficiencies

revealed by the review. In such a case, the applicant will be given an opportunity to explain or correct these

deficiencies. The changes allow the Manufacturers to be audited more comprehensively.

Revise UG-117(f) to make the retained records available to the Authorized Inspector (AI) supervisors or Review Teams for the purpose of performing reviews for the issue or renewal of Certificates of Authorization.

Explanation

解释

Certificates of Authorization will be endorsed to indicate the scope of activity authorized. Authorization may include field operations if the review team determines that these operations are adequately described in the quality control manual, and this determination is accepted by the Society.

Before issuance or renewal of a Certificate of Authorization for use of the UV or UD Stamp, the valve or rupture disk device Manufacturer’s or Assembler’s facilities and organization are subject to a review by a representative from an ASME designated organization. A written description or checklist of the quality control system, which identifies the documents and procedures the Manufacturer or Assembler will use to produce Code pressure relief valves, shall be available for review. The representative from an ASME designated organization shall make a written report to the Society, where the Subcommittee on Boiler and Pressure Vessel Accreditation will act on it as described above.

The purpose of the review is to evaluate the applicant’s Quality Control System and its implementation. The applicant shall demonstrate sufficient administrative and fabrication functions of the system to show that he has the knowledge and ability to produce the Code items covered by his Quality Control System. Fabrication functions may be demonstrated using current work, a mockup, or a combination of the two. Additionally, retained records as required by this division and the Quality Control System, shall be made available to the Authorized Inspector Supervisors or the review teams designated by the ASME.

UG-116(e)(1) UG-116 REQUIRED MARKING (e) When radiographic or ultrasonic examination has been performed on a vessel [当射线或超声波探伤已经运

用于一台容器上时] in accordance with UW-11, marking shall be applied under the Code Symbol as follows:

(1) “RT 1” when all pressure-retaining butt welds, other than Category B and C butt welds associated with nozzles and communicating chambers that neither exceed NPS 10 (DN 250) nor 11?8 in. (29 mm) wall thickness [except as required by UHT-57(a)], satisfy the full radiography requirements of UW-11(a) for their full length [在全部长度上满足UW-11(a)全部射线探伤的要求]; full radiography of the above exempted Category B and C butt welds, if performed, may be recorded on the Manufacturer’s Data Report; or

Nameplate markings as listed in UG-116(e) are currently only applicable if the vessel has been radiographed and UG-116(e)(1) states that the marking “RT1” can only be used if the welded joints have been radiographed over their entire length. UG-116(e)(2), UG-116(e)(3), and UG-116(e)(4) state that the markings “RT2”, “RT3”, and “RT4” must be used on a vessel if the radiographic requirements have been met for their respective markings even when ultrasonic examination has been used for the closure seam per UW-11(a)(7). Code Case 2235-6 allows ultrasonic examination of other welded joints other than the closure seam in lieu of radiographic examination provided specific additional criteria are met. This change will allow the vessels to be stamped with “RT-1”, “RT-2”, and RT-3” when the requirements of radiography have been met without specifically requiring a vessel to be radiographed. The specific reference to UW-51 (Radiographic and Radioscopic Examination of Welded Joints) will be deleted in the event of ultrasonic examination. The requirements in the replies are currently required under Code Case 2235-6(k) and (l).

Explanation

解释Two sample production pressure relief valves of a size and capacity within the capability of an ASME accepted

laboratory shall be selected by a representative from an ASME designated organization. Pressure relief valves

having adjustable blowdown construction shall have the control elements positioned by the Manufacturer or

Assembler for a blowdown typical of production methods

Operational and capacity tests shall be conducted in the presence of a representative from an ASME designated

organization at an ASME accepted laboratory. The pressure relief valve Manufacturer or Assembler shall be notified

of the time of the test and may have representatives present to witness the test. If a pressure relief valve with

adjustable blowdown construction selected from a Manufacturer exhibits a blowdown that exceeds7% of the

set pressure or 3 psi (20 kPa), whichever is greater, during operational and capacity tests, then an adjustment

shall be made to meet this performance condition and the operational and capacity tests shall be repeated.

This adjustment may be made on the flow test facility.

Should any pressure relief valve fail to relieve at or above its certified capacity or should it fail to meet

performance requirements of this Division, the test shall be repeated at the rate of two replacement pressure relief

valves, selected in accordance with (c)(3)(a) above, for each pressure relief valve that failed.

Failure of any of the replacement pressure relief valves to meet the capacity or the performance requirements in

UG-134 of this Division shall be cause for revocation within 60 days of the authorization to use the Code Symbol on

that particular type of pressure relief valve. During this period, the Manufacturer or Assembler shall demonstrate the

cause of such deficiency and the action taken to guard against future occurrence, and the requirements of (c)(3)

above shall apply.

UW-13(b)(5) Non-butt Welded [非对接焊接]bolting flanges shall be attached to formed heads as illustrated in Fig.

1-6The change to UW-13(b)(5) is to clarify that Fig. 1-6 is for attaching non-butt welded bolting flanges to formed heads. Adding notes (1) and (2) to sketch (a) of Fig. 1-6 is to clarify that weld symbol as shown is for illustrating the distance between the toe of the fillet weld and the tangent line of the head. Welding details shall be per Fig. 2-4. This Item is to clarify the Code, not a technical correction.

(e)Necks and Tubes up to and Including NPS 6 (DN 150) Attached From One Side Only. Necks and tubes not

exceeding NPS 6 (DN 150) may be attached from one side only on either the outside or inside surface of the vessel.

(1)The depth of the welding groove or the throat of the fillet weld shall be at least equal to 1 ? t min. The

radial clearance between the vessel hole and the nozzle outside diameter at the unwelded side shall not

exceed the tolerances given in Fig. UW-16.1 sketches (v-1), (v-2), (w-1), and (w-2). When welded from the

outside only, the neck or tube shall extend to at least flush to the inside surface of the vessel wall. Such

attachments shall satisfy the rule for reinforcement of openings except that no material in the nozzle neck

shall be counted as reinforcement. [焊接坡口的深度或角焊缝的腰高必须至少等于1 ? t min. 在非焊接侧的容器开孔

to yield which decreases its stiffness. All calculations must be performed in both the corroded and

(1) the design of the other components of the heat exchanger (i.e., tubesheet, tubes, shell, channel, etc.)

are acceptable considering the decreased the stiffness of the expansion joint. This may be accomplished by

performing an additional evaluation all of the components of the exchanger for load cases 1-3 with zero

expansion joint stiffness (KJ = 0, J = 0).

(2) the rotational stiffness at the expansion joint corners and torus is not necessary to meet the stress

limits for annular plates and straight flanges for load cases 2 and 3 shown in Table UHX-17. This may be

accomplished by modeling the corners and torus as simply supported to determine the stress in the annular

plates and straight flanges.

Appendix 1-7 1-7 LARGE OPENINGS IN CYLINDRICAL AND CONICAL[和锥体] SHELLS

1-7(a) Openings exceeding the dimensional limits given in UG-36(b)(1) shall be provided with reinforcement that

complies with the following rules. Twothirds of the required reinforcement shall be within the following limits:

1-7(a)(1) parallel to vessel wall: the larger of three-fourths times the limit in UG-40(b)(1), or equal to the limit in

UG-40(b)(2);

1-7(a)(2) normal to vessel wall: the smaller of the limit in UG-40(c)(1), or in UG-40(c)(2). 1-7(b) Openings for radial

nozzles that exceed the limits in UG-36(b)(1) 1-7(b)(1) and which also are within the range defined by the following

limits shall meet the requirements in (b)(2), (3), and (4) below:

(a) vessel diameters greater than 60 in. (mm) I.D.;

(b) nozzle diameters which exceed 40 in. (mm) I.D. and also exceed 3.4Rt; the t

　erms R and t are defined in Figs.

1-7-1 and 1-7-2;

U-2(g). The rules are limited to radial nozzles in cylindrical and conical[和锥体]shells(with the half apex angle

equal to or less than 30 degrees[半顶角等于或小于30度])that do not have internal projections, and do not include

any analysis for stresses resulting from externally applied mechanical loads. For such cases U-2(g) shall apply. This item was established to make revisions to UG-36, UG-42 and Appendix 1-7 clarifying that cones are also included in the reinforcement design rules in these sections. A note is also added to Appendix 1-7(b)(1) limiting application of the 1-7(b) rules to cones with a half apex angle not exceeding 30 degrees.

澄清了锥体也包括在规范的开孔补强设计中.在附录1-7(b)(1)中也增加了说明规定了附录1-7(b)的规则适用于半顶角不超过30度的锥体.

Appendix 1-10 Added new Appendix 1-10 Alternate Method for the Design of Reinforcement for Large Openings in Cylindrical Vessels Under Internal Pressure

新增附录1-10 内压圆筒大开孔补强设计的另一方法

Section VIII received an inquiry regarding Code Case 2398 asking if it was applicable to cases where Rn/R>0.7 and whether the limits of compensation of the Case would apply when judging overlapping reinforcement zones rather than those of UG-40(b). The author of the methods presented in the Case and in the Section VIII division 2 rewrite was contacted. According to Les Bildy, based on his past and continuing research on the subject, the answer to both of these questions should be yes.

When the Code Case was initially approved it was stated in the explanation that the Code Case was to give users a trial period that would provide the user community an opportunity to implement and provide feedback on the all inclusive nozzle reinforcement design rules that are part of the Division 2 rewrite. The Case has been in effect for three years now so it is proposed that it be incorporated as an alternative to 1-7 in a new appendix 1-10. In addition to incorporating the Case verbatim, the reference to 1-10 has been added to UG-36(b) (1). Further a new paragraph (c), similar to paragraph 4.15.14.1 of the div. 2 rewrite, is being added at the end of the proposed appendix 1-10. These two changes will address the inquiry received.

In addition to the above a few changes from the original case are being made to bring the rules up to date with the latest methods being implemented in the Div. 2 rewrite. Those changes are as follows: In step 2, the second and third

deleted from LI1. In step 4, A1 is redefined introducing the

term lambda along with its definition and A2 is redefined with

two equations instead of one. In step 9, PL is the maximum of

two choices. And lastly, in step 11, P max is the minimum of

two alternatives. These changes are identical with what is

currently proposed for the Div. 2 rewrite.

Appendix 27 27-3 PERMISSIBLE TOLERANCE FOR HEMISPHERICAL OR 2:1 ELLIPSOIDAL HEADS

If a hemispherical or 2:1 ellipsoidal head exceeds the tolerance limits in UG-81(a), and the condition cannot be

corrected, the head may be used providing the following requirements are met:

27-3(a) The inner surface of the head shall not deviate outside the specified shape by more than 3% of D nor inside

the specified shape by more than 3% of D, where D is the nominal inside diameter of the vessel shell at the point of

attachment. Such deviations shall be measured perpendicular to the specified shape and shall not be abrupt. The

deviation shall be essentially symmetric about the axial centerline of the head.The specific issue that appears to cause the problem is the general statement in 27-3 that requires that shape deviations shall be "essentially symmetric about the axial centerline" of the head. It is considered that if the true deviation is computer modeled, then it does not matter if the deviation is symmetric or not (it only means a 3-D model would be required instead of a 2-D model). The proposal is to delete that sentence in 27-3. The inquirer has indicated a need to use this provision on a completed vessel; therefore an enabling Code Case is proposed which should be annulled six months after publication of the Code revision

ASME规范简介

ASME规范介绍 3.1前言 ??? 美国机械工程师学会于1911年成立了锅炉与压力容器委员会(BPVC)，编制了锅炉压力容器的建造安全规则。1914年出版了动力锅炉规范、1925年增加了压力容器规范、1965年又增加核动力装置规范。这套ASME规范自1977年成为美国国家标准,不仅在美国和加拿大各州在法律上承认和采用它,在西方许多国家都作为参照标准来执行。在核动力装置卷册，在世界上有较高的权威，往往直接采用。法国的 RCC-M 规范和德国的 KTA 规范也直接收入了其最重要方面,再加上本国的实践而制定的。 3.2 ASME规范的构成及与核动力装置相关的内容 ASME规范是美国锅炉及压力容器方面的国家标准，共分为十一卷，内容如下：?????ASME 锅炉压力容器规范的总目录：第 I 卷动力锅炉第 II 卷材料技术条件 A 篇铁基材料(钢铁材料) ??????????
