Basic function of pipe cap in pipe

Basic function of pipe cap in pipe  

 Pipe cap, also known as plug, cap, pipe cap, head, installed on the pipe end of the external thread to cover the pipe fitting.  Used to seal the pipe, the function is the same as the pipe plug, but the pipe cap can be directly screwed on the pipe, no other pipe fittings are required.  It is generally used for sampling port at the end of the pipe. After sampling is completed, it is necessary to screw the pipe cap. Secondly, in special circumstances, after screwing off the pipe cap, the wire mouth can be connected to the pipe, and temporary continuous feeding or pumping.  The tube cap is generally used in the case of low pressure, which is easy to disassemble and repair. In the case of high pressure, the tube cap is generally not needed.  The pipe cap includes convex pipe cap, cone shell, reducer section, flat cover and the design of tightening mouth.  

The pipe cap and the head shape is similar, the material is stainless steel, the pipe cap size is relatively small, can be forged;  The head size is larger, and it is generally pressed with steel plate. The pipe cap is generally used for the end of the pipe. The head is used for the upper and lower parts of the container equipment (vertical equipment) or the left and right ends (horizontal equipment).  Convex pipe cap includes: hemispherical pipe cap, oval pipe cap, disc pipe cap and dome pipe cap.  From the point of view of force, convex pipe cap is gradually bad from the hemispherical pipe cap, but from the point of view of manufacturing difficulty, gradually good manufacturing.
