The comprehensive performance of large carbon steel pipe cap is high

　　The material of carbon steel pipe cap is as follows: Q235B, Q345B, 20 #, 35 #, 45 #, 40Cr, CCSA, CCSB, 1cr18ni9t, etc. Hebei Shengtian professional R & D design head cap, rich variety, complete specifications, high quality. The round pipe cap is a pipe cap which is composed of a rotating elliptical spherical surface and a cylindrical straight section. For example, when the pipe ends and is not ready to be extended, the elliptical pipe cap is used to weld the pipe as the end. In addition, it is used on the pressure vessel, with a pipe cap at the top and bottom, and a straight pipe section at the center, which is used as the tank of the pressure vessel.

　　The mechanical properties of elliptical cap are second only to that of hemispherical cap, but better than that of dished cap. Because the depth of elliptical pipe cap is between hemispherical and dished heads, the requirements for stamping equipment and dies and the manufacturing difficulty are also between them, that is, it is easier than hemispherical pipe cap and more difficult than dished pipe cap. In recent years, due to the spinning process, it is convenient to manufacture large diameter oval pipe cap. Our elliptical cap is widely used in medium and low pressure vessels because of its good comprehensive performance.
