Long Weld Neck Flanges
Long weld neck flanges (LWN Flange) feature a long-tapered hub that goes over to the wall thickness from a pipe. This hub gives the flange a strong reinforcement which is provided for high pressure, high temperature and sub-zero applications. The tapered hub is created by a gradual increase in thickness of the metal from the weld joint to the flange face. This makes it ideal for conditions of repeated bending caused by line expansion, contraction, or other external forces.To Prevent Turbulence at the joints and to reduce corrosion, long weld neck flanges is carefully bored to match the inside diameter of the adjoining pipe so there is no restriction in flow.
