Product Description

Our 8 Inch Carbon Steel A105 Wn Rf Flange applied to pipe connection with carbon steel A105

A Long Weld Neck Flange, or LWN, is considered a specialty flange because of its protruding neck, also referred to as a hub. The neck extends from the flat surface of the flange and receives and guides the pipe into place - the neck serves as an extension of the boring. Tapering the neck provides extra reinforcement for use in high-pressure or extreme and fluctuating temperature applications. Tapering the flange reduces the steel's thickness so that the opening of the neck blends with the pipe it receives - the tapered neck appears to be an extension of the pipe.
