DIN Weld Neck Flange
Welding Neck Flange is generally referred to as a "high hub" flange. It is designed to transfer pressure to the pipe and reduce high pressure at the base of the flange. Welding Neck Flange is a butt-welding flange with the best design among currently available flanges because of its unique structure.
