Flange, is called Flange, or Flange.Flanges are the parts that connect the pipes to each other and to the ends of the pipes.Flanges are perforated and bolted to tighten the two flanges.Gasket seals between flanges.Flanges are threaded (wire) flanges and welded flanges.
Stainless steel flange, which is called flange, or flange.It's a part of a pipe that connects to a pipe.Connect to tube end.Flanges are perforated and bolts can be threaded to tighten the two flanges.Gasket seals between flanges.Flange pipe fitting, flanged pipe fittings) refers to the pipe with flange (flange or flange).It may be cast, threaded or welded.Flange, joint, consists of a pair of flanges, a gasket, and a few bolts and nuts.The gasket is placed between the sealing surface of two flanges. After tightening the nut, the specific pressure on the surface of the gasket reaches a certain value and produces deformation.Some pipe fittings and equipment have their own flange, is also a flange connection.Flange connection is an important way of pipeline construction.
Flange connection is easy to use, can withstand greater pressure.Flange connection is widely used in industrial pipelines.In the home, the pipe diameter is small, and is low pressure, can not see the flange connection.If you are in a boiler room or production site, there are flanged pipes and equipment everywhere.
Generally speaking, the role of the flange is to make the pipe fitting joint fixed and sealed.
The main role
1. Connect the pipeline and maintain the sealing performance of the pipeline;
2. easy to replace a section of pipeline;
3. Easy to disassemble and check the pipeline;
4. easy to close a section of pipeline.
Type of flange connection
Flat welded flange
Plain welded flange with neck

Eight blind flange
Loosen the flange on the welding ring
Rotate the flange
Stainless steel classification
Stainless steel flange is usually divided into 304, 304L, 316, 321, 316L and other categories.
