ASTM A694 GR F52 1500LB 8inch Weld Neck Flange

HAIHAO GROUP FLANGE TYPE:

The weld neck flange is connected with the pipe from the neck in butt welding method, that means the neck should be have same material and same outer diameter and wall thickness with the pipe. The butt welding joint could provide a strong connection between the pipes and flanges which is better for high pressure application.
