Carbon steel pipe caps are bearing parts

Carbon steel caps are used for pipe fittings welded to pipe ends or mounted on pipe end external threads to cover pipes. Used to close the pipeline, the function is the same as the pipe blocking. The tube cap comprises a convex tube cap, a cone shell, a reduced diameter section, a flat cap and a tightening mouth design. Gb carbon steel pipe cap Convex pipe cap includes: hemispherical pipe cap, oval pipe cap, saucer pipe cap and spherical cap. From the point of view of force, the hemispherical tube cap of convex tube is gradually bad, but from the point of view of manufacturing difficulty, it is gradually better to manufacture.

Carbon steel pipe cap, also known as plug, cap, cap, bulkhead, used to close the pipeline, the same role as the pipe plug, but the cap can be directly screwed on the pipe, no other pipe fittings. The tube cap comprises a convex tube cap, a cone shell, a reduced diameter section, a flat cap and a tightening mouth design.

Material and standard of tube and cap

Carbon steel tube cap materials are mainly Q235,20#, A3, 16 manganese, Q345B, 45 steel and so on. The standard is GB/T25198-2010(pressure vessel head standard), and pipeline standard GB/T12459-2005,GB/T13401-2005 and so on.
