DN1500 300LB 24" Forged Steel Flanges , Long Weld Neck Flange
Forged Flange Stainless Steel 304/316 Long Weld Neck flange ASTM B16.5 1/2"-24"
Processing method: high-precision CNC lathe turning, ordinary lathe fine turning, argon arc welding and other processing
Application scope: boiler pressure vessel, petroleum, chemical, shipbuilding, pharmaceutical, metallurgy, machinery, food and other industries
Long and high neck flange:
The neck height is higher, which improves the rigidity and bearing capacity of the flange. Compared with butt welding flanges, the welding workload is large, the welding rod consumption is high, and it cannot withstand high temperature and pressure, repeated bending and temperature fluctuations, but it is more convenient for on-site installation and can omit the process of welding seam scratching, which is more popular.
