Flange connection is to fix two pipes and pipe fittings on a flange. There will be a gasket between the two flanges. Fasten it together with bolts to complete the connection. Some pipes and fittings already have their own flanges, which can also be regarded as flange connections.
Flange connection is an important connection method in pipeline construction. It is easy to use and can withstand greater pressure. In some scenarios where high pressure piping is required, flange connections can be seen everywhere.
It is widely used in chemical, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, electricity, shipbuilding projects, etc. because the flange has good comprehensive performance.
According to the connection method, the stainless steel flanges can be divided into the following types: plate type flat welding flange, flat welding flange with neck, butt welding flange with neck, socket welding flange, threaded flange, flange cover, loose flange with neck butt welding ring, flat welding ring loose sleeve method Flange, ring groove face flange and flange cover, large diameter flat flange, large diameter high neck flange, eight-character blind plate, butt welding ring loose flange, etc.
Common Failures of Flanges
In the continuous production process, flanges are easily affected by factors, such as medium corrosion, scouring, temperature, pressure, and vibration. Therefore, leakage problems inevitably arise. The size error, the aging, and the improper installation of the sealing part will cause the leakage issues. If the leakage problem cannot be dealt with in time, the leakage will expand rapidly under the scouring of the medium. It results in the loss of materials, the shutdown of the enterprise, and the destruction of the production environment. If it is toxic, flammable, and explosive media leakage, it may also cause serious casualties.
