Large-diameter flange is one of the flanges. It is widely used in the machinery industry, chemical industry, wind power generation industry, and sewage treatment industry, and is highly praised and supported by users.

Large-diameter flanges are used for butt welding of flanges and pipes. They are mainly used in welding technology. They have good use characteristics and performance. They have reasonable structure, high strength and rigidity, and can withstand high temperature and high pressure, repeated bending and temperature fluctuations. ,

Flange connection is an important and widely used connection method in pipeline engineering. The so-called "flange connection" is to fix two pipes, pipe fittings or equipment on a flange first, then add a flange gasket between the two flanges, and then use bolts to connect the two flanges. The discs are pulled tight to hold them tightly together. However, the quality of flange sealing performance will be affected by many factors.
