The stainless steel pipe end cap is processed and customized. The head is the end cap on the pressure vessel and is a main pressure-bearing part of the pressure vessel. The role played is the sealing effect. One is to make the upper and lower bottoms of the tank-shaped pressure vessel, and the other is that the pipe is at the end and is not going to extend forward. Then a head is used to seal the pipe in the form of welding.
