ASME B16.9 A234 WPB Large Diameter 72 inch Cap of Pipe Fitting

A pipe cap is a pipe fitting welded to the end of the pipe or threaded to cover the pipe. Used to close the pipe, the function is the same as the pipe plug. The pipe cap is also called a plug, a cap, a pipe cover, and a stuffy head. Used to close the pipe, the function is the same as the pipe plug, but the pipe cap can be directly rotated on the pipe, no other pipe fittings. It is generally used at the end sampling port of the pipe. After the sampling is completed, the pipe cap should be screwed on. The other is that under special circumstances, after the pipe cap is removed, the pipe can be connected with the wire mouth, and the material can be taken or pumped continuously. Pipe cap in the case of low pressure, easy to disassemble and repair, high pressure generally do not use the cap. The cap comprises a convex cap, a conical shell, a variable diameter section, a flat cover and a tight port. The pipe cap is similar to the head shape, the material is more stainless steel, the pipe cap size is smaller, can be forged; the head size is larger, generally pressed with steel plate, the pipe cap is generally used at the end of the pipe, Head for upper and lower container equipment (vertical equipment) or left and right end (horizontal equipment). Convex tube cap includes: hemispherical tube cap, elliptical tube cap, disc tube cap and ball crown tube 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.
