ASTM A182 F316L ASME B16.5 Stainless Steel Weld Neck RF Forged Flange For Water Treatment
ASTM A182 F316L ASME B16.5 Stainless Steel Weld Neck RF Forged Flange For Water Treatment
What is WN (WELD NECK) flange ?
Neck flat welded flange full name with neck flat welded steel pipe flange, is the steel pipe, pipe fittings, etc. into the flange through the fillet weld and equipment or pipe connection flange.
Advantages
Flat welded flange with neck is also a flat welded flange, because it has a short neck, which improves the strength of the flange and improves the bearing strength of the flange. So it can be used on higher pressure pipes.
Disadvantages
The cost is higher than that of flat welded flange, and it is easier to bump during transportation due to its shape characteristics.
Description of A182 F316L
