Flange

A flange is a fundamental mechanical connecting component widely used in global industrial pipeline systems.It is mainly applied to connect pipes,valves,pumps,pressure vessels and other pipeline accessories.With a circular disc structure and evenly distributed bolt holes on the outer edge,flanges achieve detachable sealed connections with gaskets and bolts,which greatly facilitates pipeline assembly,daily maintenance,part replacement and system reconstruction.

There are numerous structural types of flanges to adapt to diverse working conditions,including weld neck,slip on,socket weld,threaded,blind and large diameter flanges.All standard flanges are produced in strict accordance with international piping standards such as ASME B16.5 and ASME B16.47.They cover complete pressure classes ranging from Class 150 to Class 2500 and full NPS size specifications.Common flange face types consist of Raised Face(RF),Flat Face(FF)and Ring Type Joint(RTJ),ensuring excellent sealing performance under various temperature and pressure conditions.

Various material options are available for flange production,mainly including carbon steel,stainless steel,alloy steel and duplex steel.Carbon steel flanges provide reliable structural strength and high cost performance for conventional pipelines.Stainless steel flanges possess superior corrosion resistance,oxidation resistance and durability,suitable for harsh chemical environments.Different materials and structures meet diversified requirements of medium properties,working temperature and bearing pressure.

With optimized structural design,flanges effectively disperse internal stress,resist fluid impact and reduce leakage risks.Stable connection performance guarantees long-term safe operation of entire pipeline networks.They are extensively adopted in petroleum industry,chemical engineering,power generation,water conservancy,water treatment,marine engineering and municipal pipeline projects.

Precision forging,fine machining and rigorous quality inspection ensure accurate dimension tolerance and stable mechanical properties.As core basic fittings in pipeline engineering,flanges play an irreplaceable role in all industrial fluid transmission systems around the world.
