这里介绍的单卡套接头有两个体系,一类又称为24度压缩式管接头,常用于液压管道系统，设计制造标准包括DIN2353/ISO8434-1，JIS B2351，SAE J514。
另一类通常由仪表管接头的生产商提供，没有统一的制造标准，如CPI接头，ONE-LOK接头等。
常用的单卡套接头有单刃口卡套接头和双刃口卡套接头之分。
一.单刃口卡套接头结构如下：单刃口卡套接头的动作原理：管子插入接头并保证与接头底部（2）接触，卡套右端在螺母的拧紧顶压下，左端被挤进接头体内锥孔与管子间的间隙里，使卡套的外锥面形成锥面接触密封，卡套的内刃口（1）嵌入钢管外壁，在钢管的外壁压出一个闭口环形槽和一个环形凸起（4），形成密封；进一步拧紧螺母，使卡套中部稍微凸起，产生弹性变形，弹性应力使卡套右端面与螺母锥面产生摩擦力，以防螺母松动，弹性变形部分可吸收液压管道中的震动，另外，卡套尾部（3）也紧抱钢管形成一道抵触密封。
二.双刃口卡套接头结构如下：双刃口卡套接头用两个刃口卡套，即一个切入刃口（1）和一个止动刃口（2），止动刃口不仅形成了第二道密封，而且可防止切入刃口咬伤管子，从而提高了接头的耐振能力、抗脱拔能力。
卡套密封多为金属对金属的密封形式，为了提高卡套接头的密封性和重复安装性，现在有了带有弹性密封圈的卡套，见下图。
以弹性密封取代传统卡套接头采用的硬密封方式，密封效果更加理想，复装性更佳。

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. Example :Tube SS316 1/2” O.D.x0.065” at 700 F.5100psi °x 0.82 = 4182psi.Therefore 4182 psi is the maximum allowableworking pressure of SS316 1/2” O.D.x0.065”wall tubing.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.

卡套式管接头介绍 Company number：【0089WT-8898YT-W8CCB-BUUT-202108】卡套式管接头1、卡套式管接头用途：卡套式管接头适用于油、气、水为介质的管路系统。
适用压力范围：（G）25Mpa，（J）40Mpa。
2、卡套式管接头特点：卡套式管接头具有结构先进、性能良好、使用方便、不用焊接、不必将配管扩口，等一系列优点。
因此，卡套式接头已广泛应用于各类机械的液压、气动系统中，但卡套式管接头的卡套制造精度较高，由于工艺复杂，不宜零星或小批制造，需专业生产。
3、卡套式管接头结构与工作原理：卡套式管接头主要包括三部分：（1）具有24°锥孔的接头体。
（2）带有尖锐内刃的卡套（3）起压紧作用的螺母。
旋紧螺母时，卡套在压力下被推进24°锥孔。
并随之下而变形，使卡套与接头体内锥面形成球面接触密封。
同时卡套在内刃口嵌入管子的外壁，在外壁上压出一个环形的闭口缘边，从而起到可靠的密封作用，卡套中部稍有拱形凸起，具有一定弹性，有利于密封和防止螺母松动，卡套尾部也径向收缩而抱住管子。
参见下图。
卡套式管接头采用公制细牙螺纹或锥螺纹与机件连接，且要采用密封垫圈，当中压级时推荐用密封垫圈（JB1002-77），高压时推荐用组合密封垫圈（JB982-77）或密封垫圈（JB1002-77）。
4、卡套式管接头品种和产品代号：卡套式管接头共有29种品种，配用外径4m/m至42m/m17种无缝钢管或铜管，共计有1364种产品，详见目录。
产品代号含义：5、订货须知：（1）用户根据GB标准或JB标准或有关规格参数从目录中查到KT※-※，依照相应页码可知所需产品代号及该产品的有关技术数据。
