双卡套管接头双卡套管接头是由美国人佛瑞德A.雷能在1947年发明的。

对比于螺纹、扩孔、单卡套等接头形式，双卡套管接头是一种兼顾密封及安全的小口径管道连接件。

一个优良的双卡套管接头可以做到：●承受高达管子爆破的压力而不泄漏。

●可用于真空及高压液体系统。

●可在低温状态下工作保证密封。

●在管子的最高额定温度下持久的密封。

●可重复拆装且保证密封。

双卡套管接头的这些性能使其广泛地应用于仪器仪表、石油化工、电力、气体等行业。

一．双卡套管接头的结构二．双卡套管接头的安装步骤：第一步：将管子插入接头，确保管子端部达到接头底部，并用手指拧紧卡套螺母。

第二步：在卡套螺母的6点位置做一标记。

第三步：用扳手固定接头本体，旋转卡套螺母一又四分之一转，这时所做标记旋转540度，至9点钟位置。

三．双卡套管接头的工作原理：在卡套螺母拧紧一又四分之一转的过程中，接头内部依次完成下面设计好的动作。

1．通过螺纹机械式推进，卡套螺母向前运动推动后卡套向前，同时后卡套推动前卡套向前运动。

2．接头本体的尖端向内挤压前卡套。

3．前卡套消除它的内径与管子外径间的公差。

4．随着后卡套的推进，前卡套向前向内动作，后端抬起，与接头本体斜面形成密封。

5．随着管子更大的变形和本体斜面与前卡套接触面的增大，更大的阻力迫使后卡套向内动作，从而在管子上形成第二道牢固的支撑。

6．在卡套螺母拧紧一又四分之一转，它前进了1/16inch（1.52mm），接头完成了密封，抱紧管子的作用。

ASME Accredited Nuclear &ISO9001QualitySystemCatalog Number 01-4January, 2003Hydraulic Swaging Unit for Pre-Swaging Over 1ISO 9001 Certified Fitting and Valve ManufacturerIntroductionConstruction of Dk-Lok FittingsDk-Lok Tube Fittings have been designed specifically forthe many demanding applications chemical, petroleum,power generating, pulp, paper and various types ofmanufacturing industries. They provide a highly reliable,leakproof and torque free seal on all tubing connections.Dk-Lok Tube Fittings are commonly used oninstrumentation,process and control systems or any otherapplication where a high quality tube fitting is requiredThe Dk-Lok body, nut, back ferrule and front ferrule aremanufactured under very close tolerance control andmonitored through Statistic Process Control and are Heat-Code Traceable.The twin ferrule design performs leak proof sealing with allassembly and reassembly motion being transmitted axiallythrough the tubing. This results in no radial movement of thetubing upon assembly and reassembly.Therefore, the tubingis not stressed and the mechanical integrity is maintained.This is the result of close tolerance control in machining,surface smoothness and hardness of each and every part ofthe Dk-Lok tube fitting. Through this swaging action, theDk-Lok fitting becomes integrated mechanically with thetubing connected.Dk-Lod fittings are available in Stainless Steel, Brass andCarbon Steel as standard materials, and can be manufacturedfrom various materials upon request. Dk-Lok fittings aretested according to JIS B2351 & BS4368 standards.NutBody ThreadFront FerruleBack FerruledABUnit:mmHex.Standard of Quality for Dk-Lok FittingsTubing has many benefits over piping. Since tubing is ableto be bent, this allows lower pressure drop due to fewerconnections. This in turn reduces costs because of lessfabricating manpower. Dk-Lok connections do not requirethreading or welding, and are assembled by standard wrenchmake-up. This results in less assembly and maintenance costs.Tubing & Tube Fitting BenefitsFor safe, reliable and leak-free seals, tubing should beconsidered as a fitting component. Quality Dk-Lok fittingsprovide the best performance when good tubing is used. Careshouldbe taken and general rules followed to have good tubingTubing SelectionTubing - General Rules1. For leak-free sealing, the tubing surface is very important.The Tubing must have a good surface free from scratches,draw mark, flat spots or dirt.2. In case of welded tubing, it should not have a visible poorbead on its outside diameter.ing like tubing and fitting material is essential for thesame thermal compatibility and corrosion resistance.The tubing material should be compatible with the process fluid, temperature and environment.4.Tubing must be softer than fitting material. When tubingand fittings are made of the same material, the metal tubing must be fully annealed.5. Tubing hardness must be selected according to theinformation in the table 2 to 8.6. Do not select a too thin or thick wall. A too thin wall maycollapse and a too thick wall may not properly be deformed by the ferrule action. The wall thickness selection should be based on the applicable pressure, temperature, shock and vibration.7. Tubing with oval or out-of-roundness appearance may notfit into the fitting. Do not force the tubing into the fitting, itmay damage the fitting sealing system of the nut, ferrules, or the body.Purchasing the tubing based on the industrial standards suchTubing Temperature RatingsThe Maximum and Minimum operating temperaturesfor various tubing materialTemperature De-rating FactorsThe allowable working pressure is determined by various temperatures.To determine the working pressure at the specific temperatures, multiply the working pressure at ambient temperature shown in table 2~8 by the factor shown in table 1.

Tubing should be free of scratches for bending or flaring.Special Alloy TubingDK-Lok tube fittings are designed for a wide range of leak-free application including gas leak proof and vacuum service.Gases can escape even the most minute leakpath due to their small molecules, Tube must therefore be carefully handled not to get scratched.Use heavier wall tubing for gas service. Heavy wall tubing resists ferrule action by coining out minor defects of the tube surface and thin wall tubes may collapse with little resistance to ferrule action.For Gas service, use the tubing of the un-shadowed section in table 5 - 8.Tubing for Gas applicationDK- Lok Fittings in S316 Stainless Steel provide highly reliable performance from Cryogenic Temperatures to High Temperature Levels.S316 Stainless Steel Temperature Rating : -321°F to 1200°F (-196°C to 649°C)Cryogenic Temperature are considered to be Temperatures Below : -100°F (-73°C)Cryogenic ServicePressure Rating Equivalents :1) 1 bar = 100 kPa = 14.51 psi 2) 1 kPa = 0.01 bar = 0.1451 psi3) 1 psi = 0.069 bar = 6.89 kPa 4) 1 kg/cm 2 = 0.98 bar = 14.22 psiMany Dk-Lok tube fittings have a male or female pipe end.These ends sometimes have a lower pressure rating than the pressure rating of the tube fitting end.Pipe ThreadPipe thread sealant is essential to ensure leak-free seal. Since the Teflon tape is commonly used, we provide information of recommended tape width, as well as the numbers of thread to be wrapped. The Teflon TM tape fills the voids between threads and prevents galling on pipe threads. The sealant usually contains a lubricant.Pipe Thread SealantTable 9. Pipe End Pressure RatingUnit : Inches * ASME B1.20.1-NPT The ratings shown above are based on ASME B31.3-1999Female pipe ends have lower ratings than male pipe in a given size due to the inner and outer diameters of female threads being larger than those of male pipe ends.The ratings shown above are reference only.Note: 1. Wrap Teflon TM Tape clockwise from first thread. Do not overhang the first thread, as the tape may get intothe fluid system.2. Teflon TM tape has a temperature limit of 230°C( 450°F).Note: The information shown in table 1-10 are not for design purpose, but for reference only.

什么是双卡套式管接头双卡套管接头(two ferrule tube fitting)是由美国人佛瑞德A.雷能在1947年发明的。

对比于螺纹、扩卡套等接头形式，双卡套管接头是一种兼顾密封及安全的小口径管道连接件。

一个优良的双卡套管接头可以●承受高达管子爆破的压力而不泄漏。

●可用于真空及高压液体系统。

●可在低温状态下工作保证密封。

●在管子的最高额定温度下持久的密封。

●可重复拆装且保证密封。

双卡套管接头的这些性能使其广泛地应用于仪器仪表、石油化工、电力、气体等行业。

一．双卡套管接头的结构:二．双卡套管接头的常规安装步骤：第一步：将管子插入接头，确保管子端部达到接头底部，并用手指拧紧卡套螺母。

第二步：在卡套螺母的6点位置做一标记。

第三步：用扳手固定接头本体，旋转卡套螺母一又四分之一转，这时所做标记旋转540度，至9点钟位三．双卡套管接头的工作原理：在卡套螺母拧紧一又四分之一转的过程中，接头内部依次完成下面设计好的动作。

1．通过螺纹机械式推进，卡套螺母向前运动推动后卡套向前，同时后卡套推动前卡套向前运动。

2．接头本体的尖端向内挤压前卡套。

3．前卡套消除它的内径与管子外径间的公差。

4．随着后卡套的推进，前卡套向前向内动作，后端抬起，与接头本体斜面形成密封。

5．随着管子更大的变形和本体斜面与前卡套接触面的增大，更大的阻力迫使后卡套向内动作，从子上形成第二道牢固的支撑。

6．在卡套螺母拧紧一又四分之一转，它前进了1/16inch（1.52mm），接头完成了密封，抱紧作用。

卡套式管接头压力范围：250 –800 Bar（25MPa-80MPa）。

适用钢管尺寸范围：Φ4mm～Φ42mm。

适用材料：碳钢和不锈钢。

制造材料：304 316 20#卡套式管接头组成：接头体、卡套（前卡套、后卡套）、螺母。

密封原理：当卡套和螺母套在钢管上插入接头体后，旋紧螺母时，卡套前端外侧与接头体锥面贴合，内刃均匀地咬入无缝钢管，形成有效密封。

卡套连接方式优点：1、结构简单、密封性能可靠、使用方便、制造精良、外形轻巧美观。

2、不用加垫圈、不用焊接、节省材料、反复装拆性能好。

3、由于卡套管接头不用焊接，从而减少了管道杂质对系统性能的影响。

因此，卡套式管接头正日益广泛地应用在以油、气、为介质的液压气动设备管道中，特别适用有燃烧危险、高空作业和装拆频繁的场合。

卡套接头的装配A安装1、锯下合适长度的无缝钢管，去除端口毛刺。

钢管端面要与轴线垂直，角度公差不大于0.5度。

如果钢管需要折弯，则钢管端面至弯曲部位的直线段长度不能少于三倍螺母的长度。

2、把螺母和卡套套在无缝钢管上。

注意螺母和卡套的方向，不要装反。

3、在预装配接头体螺纹和卡套上涂上润滑油，把钢管插入接头体，（钢管一定要插到底）用手旋紧螺母。

4、拧紧螺母直至卡套卡住钢管，这个转折点可以通过拧紧力矩的增加感受到（压力点）。

5、达到压力点后，再将螺母拧紧1/2圈。

6、将预装配接头体拆下，检查卡套刃边的嵌入情况，可见的突起带必须填满卡套前端的空间。

卡套可以稍微旋转，但不能轴向移动。

7、最终安装，将实际安装中的接头体的螺纹涂上润滑油、压紧螺母与之配合拧至可感觉到的拧紧力增加为止，接着再拧紧1/2圈安装完毕。

B重复安装所有的卡套接头都可以多次重装，但要保证零件无损坏且清洁。

1、把钢管插入接头体直至卡套贴紧接头体内锥面，用手拧紧螺母。

2、用扳手拧紧螺母，直至拧紧力矩急剧增大，再拧紧1/4至1/2圈即可。

C检查可拆下钢管检查装配是否合乎要求：卡套端部的钢管上应该有均匀的轻微凸起。
