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
RTJ Weld Neck Flange. Raised face weld neck flange bottom side has a small portion surrounding the bore that protrudes from the face. Gasket seat will be placed in this raised area. Depending on the different pressure ratings, different height of raised face will be adopted. For example, 150# and 300# flange raised face height is 1/6'', above 300# the height will be above 1/4''.
