Description

The stainless steel flange is mainly a part that connects the pipe to the pipe. According to the structure type, there are integral flange, looper flange and threaded flange. Common integral flanges have flat weld flanges and butt weld flanges. Flange fittings refer to fittings with flanges (flanges or lands). It can be cast or it can be made by screwing or welding. Flange joints consist of a pair of flanges, a gasket and a number of bolts and nuts. The gasket is placed between the two flange sealing surfaces. After the nut is tightened, the specific pressure on the surface of the gasket reaches a certain value and then deforms, and fills the unevenness on the sealing surface to make the joint tight. A flanged joint is a detachable joint. There are holes in the flange, bolts can be worn to make the two flanges tightly connected, and the flanges are sealed with gaskets. According to the connected parts, it can be divided into container flange and pipe flange.
