Advantages of Different Shape Stainless Steel Pipe Fitting Cap

　　The structure stress of stainless steel cap is related to the cooling rate, shape and chemical composition of the workpiece in martensitic transformation zone. The final result of structural stress change of stainless steel pipe fitting cap is surface tension stress and core compression stress, which is just opposite to thermal stress.

　　The ratio of long axis to short axis of the rotating elliptical spherical busbar of high pressure stainless steel pipe fitting cap is 2.0, which is customarily called the standard elliptical stainless steel pipe fitting cap. The mechanical properties of the elliptical stainless steel pipe fitting cap are inferior to that of the hemispheric stainless steel pipe fitting cap, but superior to that of the dish stainless steel pipe fitting cap. Because the depth of the elliptical stainless steel cap is between the hemispherical cap and the dish stainless steel cap, the requirements for stamping equipment and die and the manufacturing difficulty are also between the two, that is, it is easier than the hemispherical cap and more difficult than the dish stainless steel pipe fitting cap. In recent years, the use of spinning technology has brought convenience to the manufacture of large diameter elliptical stainless steel caps. Elliptical cap is widely used in medium and low pressure vessels because of its good comprehensive performance. Under normal circumstances, ASTM A106 2 Inch Sch10 Stainless Steel Pipe Fitting Cap are often used at both ends of pressure vessels. Moreover, the use of pipe caps is a mitigating part of pipe fittings when the force at the end of the pipe can be blocked. There are many kinds of stainless steel pipe fitting cap. They are also widely used. Common standards: JB/T4746, GB25198, GB/T12459, GB/T13401, SH3408.
