Socket Welded Flange

Rigidity and strength: socket welded flanges are connected to the pipeline by socket welding, which has high rigidity and strength and can withstand large pressure and load.
Sealing performance: The sealing surface of socket weld flanges usually adopts the forms of raised face (RF), concave-convex face (MFM), tongue and groove face (TG), etc., which can closely match with the gasket and provide good sealing performance.
Wide range of applications: Socket welding flanges are suitable for pipes and fittings made of various materials such as carbon steel, alloy steel, stainless steel, etc., and can meet the needs of different industrial fields.
Easy installation: Compared with welding flanges, socket welding flanges are easy to install and do not require complicated welding operations, saving installation time and cost.

Socket weld flanges are widely used in piping systems of boiler pressure vessels, petroleum, chemical, shipbuilding, pharmaceutical, metallurgy, machinery and other industries. Especially in working environments that need to withstand higher pressure and temperature, socket welded flanges are favored for their good sealing performance and strength.

Pre-installation inspection: Before installing socket weld flanges, it is necessary to check whether their specifications and materials are compatible with the piping system, and to ensure that the sealing surface is flat and clean. It is also necessary to check whether the insertion depth of the pipe end meets the requirements.
Correct installation: Installation is carried out in accordance with the installation instructions or drawings to ensure that the connection between the socket weld flange and the pipeline is tight and firm. Appropriate welding methods and parameters must be used during installation to ensure the quality and strength of the weld.
Regular inspection: Regular inspection of socket welding flanges includes checking whether the weld is loose, whether the marking surface is worn or damaged, etc. If problems are found, they should be dealt with in time to avoid leakage and other safety accidents.
Cleaning and maintenance: Regularly clean the socket welded flanges and their connecting parts, remove oil, dust and other impurities on the surface, in order to maintain good connection status and sealing performance.
