ANIS B16.5 Stainless Flange

PN1.0MPa American Standard ANIS B16.5 304 Butt Welding Stainless Steel Pipe Fitting Flange M10-M27 Forged Flange

Flange connection is to fix two pipes, pipe fittings or equipment on a flange plate respectively, add flange pads between the two flange plates, and fasten them together with bolts to complete the connection. Some pipe fittings and equipment have their own flanges, which are also flange connections. Flange connection is an important connection method for pipeline construction. The flange connection is easy to use and can withstand greater pressure. In industrial pipelines, flange connections are widely used. In the home, the pipe diameter is small, and it is low pressure, and the flange connection is invisible. If it is in a boiler room or production site, flanged pipes and equipment are everywhere.

1. According to the connection method, the type of flange connection can be divided into: plate flat welding flange, neck flat welding flange, neck butt welding flange, socket welding flange, threaded flange, flange cover, neck pair Welding ring loose flange, flat welding ring loose flange, ring groove face flange and flange cover, large diameter flat flange, large diameter high neck flange, eight-shaped blind plate, butt welding ring loose flange, etc.

Welding quality

As for iron plate welding flanges, many customers question whether the quality of iron plate welding flanges is better than forged welding flanges. In fact, the quality of iron plate welded flanges is the same as that of forged welded flanges, but where can iron plate welded flanges not be guaranteed? That is, the material of iron plate welded flanges is the least guaranteed, because In the general process, the density of the iron plate welded flange is not a problem, but during the production process, the blank of the iron plate welded flange is rarely tested. Therefore, after the production, it does not pass The material of the tested iron plate welding flange cannot be guaranteed..
