WN Flange

Weld neck flange is a high-strength flanged fitting with an integrated tapered neck for butt-welding with pipelines.
It is manufactured by forging steel billets, followed by heat treatment and precision machining of sealing surfaces, bolt holes and welding ends.
It delivers excellent structural strength and stress distribution, ensuring leak-proof connections for high-pressure, high-temperature pipeline systems and facilitating convenient disassembly for equipment maintenance.
It is widely applied in petroleum, natural gas, chemical, power, metallurgy and other heavy-duty industrial pipeline projects with harsh working conditions.
