ANSI ASME B16.5 Forged Welding Neck Flanges

Welding Neck Flanges are probably the most easiest to recognize amongst the various types of flanges available in the market. The ASME B16.5 Weld Neck Flange is produced with a long tapered hub, which transitions gradually over to the wall thickness from a pipe or fitting.

The long tapered hub present on the ASME B16.5 Carbon Steel Weld Neck Flange is what provides an important reinforcement to this component. This reinforcement provided by the flanges is useful in several applications involving high pressure as well as sub-zero and / or elevated temperatures. Therefore Alloy Steel 150 Welding Neck Flange is used across a wide range of industries. The smooth transition from flanges thickness to pipe wall thickness or fitting wall thickness effected by the taper is extremely beneficial, especially under conditions, where repeated bending may occur. The bending could be caused by either line expansion or other variable forces.
