The weld neck (or welding neck) flange is bored to the ID of the pipe and has a high neck to which pipe is welded. Probably the best welding flange available because of its high, heavy neck. Used wherever a sound welded joint connection is needed. Grades: Alloy Steel ASTM more...
Weld Neck Flanges are drilled (machined) with the wall thickness of the flange having the same dimensions of the matching pipe. The lighter the pipe is, the larger the bore, conversely, the heavier the pipe, the small the bore. Our Weld Neck Flanges, Welding Neck Flanges are normmore...
