ASME B16.11 Stainless Cap, A304 304L, A316 316L, 4 Inch, 3000#, Polished Treatment

Pipe cap is also called head, plug, cover, pipe cover, stuffy head. The purpose of the pipe cap is to cover the pipe fittings welded to the end of the pipe or to the outer thread of the end of the loading pipe. The pipe cap is used to close the pipe, and the function of the pipe cap is the same as that of the pipe plug. The difference is that the blind plate can be removed, while the tube cap is welded to the pipe, the tube cap can not be removed, and the tube cap includes the design of convex tube cap, cone shell, variable diameter section, flat cover and contraction port.

Convex cap includes: disc cap, ball crown cap, oval cap and hemispherical cap. From the point of view of force, the hemispherical tube cap is not good, but from the point of view of manufacturing difficulty, it is easy to manufacture.

The pipe cap can be divided into copper pipe cap, iron pipe cap, stainless steel pipe cap, plastic pipe cap and so on.

There are about 17 kinds of pipe caps classified according to pressure grade, which is the same as that of American pipe pressure grade, Sch5s,Sch10s,Sch10,Sch20,Sch30,Sch40s,STD,Sch40,Sch60,Sch80,XS;Sch80,Sch100,Sch120,Sch140,Sch160,XXS; the most commonly used are STD and XS. The pipe cap is not very common in industrial buildings. The pipe cap is only used at the end of the pipe to close the pipe. It is basically the same as the blind plate, that is, the blind plate can be disassembled, and the pipe cap is welded to the pipe and is very close to the blind plate.

we should pay attention to the process of manufacturing: the correct way is: material (line)-small plate assembly-molding-non-destructive testing if the type before the test is wrong, can not ensure the quality of the product after molding. That is to say, nondestructive testing refers to the final nondestructive testing. The pipe cap is not very common in industrial buildings. It is only used at the end of the pipe to close the pipe. It is basically the same as the blind plate, that is, the blind plate can be removed, but the cap can not be removed. The cap is welded to the pipe and is very close to the blind plate.
