Method for welding flange parts

With the rapid development of long-distance pipeline construction at home and abroad, pipeline pressure testing has become an indispensable part of pipelines. Before and after the pressure test, each pipe is swept through the ball, usually 4 to 5 times butt-welded steel flanges are used to weld flanges and pipes. Reasonable structure, strength and rigidity, can withstand high temperature and pressure, repeated bending and temperature fluctuation, reliable sealing.

Welding of welding flange parts: Weld simple, rolled, forged, stamped or machined parts into complex parts to reduce costs. Cold forging is a forming process below the material's recrystallization temperature, and forging is performed at a temperature below the recovery temperature.

However, this connection is only part of the equipment, such as the connection between the flange and the water pump, so it is not good to call the pump a "flange part". The American standard flange and flange blank are usually used in the welding process. We specialize in producing butt welded carbon steel flanges, flat welded flanges, carbon steel flanges, Japanese standard flanges, bulk flanges, etc. For Lan products, these products are trusted by customers.

Butt-welded steel flanges are used for welding flanges and pipes. Reasonable structure, high strength and stiffness, can withstand high temperature and pressure, repeated bending and temperature fluctuations. Reliable sealing. Welded flanges with a nominal pressure of MPa use a concave and convex sealing surface. It is nothing more than a connection type such as a plane or a face.
