ASME A105 WN Flange

Weld neck flange(WN flange) attach to the pipe by welding the pipe to the neck of the pipe flange. The allows for the transfer of stress from the weld neck pipe flanges to the pipe itself. This also reduces high stress concentration at the base of the hub of the weld neck flanges. 

Weld Neck Flange Material:

Carbon steel: ASTM A105,ASTM A105N,GB 20,C22.8.

Alloy steel: ASTM A350 LF2,CL1/CL2,ASTM A182 F5,F9,F11,F12,F22,F91.
