Socket pipe cap

Socket is widely used in nuclear power, chemical, food, pharmaceutical and other industries, the head of pressure vessel is a mechanical element, element is under pressure.

Socket also known as high pressure pipe cap, forging steel pipe cap, nominal size: 1/4 “- 5”, DN20-DN200, applicable medium: water, steam, oil etc.

The quality directly affects the operation of the pressure vessel. For the forming of tailor-welded before and after the split forming butterfly head welding tests, it is very important.

1,Before forming welding: ensure welding quality (surface testing, pay attention to the welding current, welding method, etc.), the best ray detection. Internal grinding with the base level before stamping. Ray detection after forming.

2,After the split forming welding: guarantee welding quality (surface testing, pay attention to the welding current, welding method, etc.), radiographic testing.

Butterfly head is widely used, so the welding head is quite important for butterfly, so at the time of welding head welding technique is very important.
