  • JIS Welding Neck Pipe Fittings Flange

Product Information

The long tapered hub provides an important reinforcement for use in several applications involving high pressure, sub-zero and / or elevated temperatures. The smooth transition from flange thickness to pipe or fitting wall thickness effected by the taper is extremely beneficial, under conditions of repeated bending, caused by line expansion or other variable forces.

 

This flange type will be welded to a pipe or fitting with a single full penetration, V weld (Buttweld).
