Raised Face Welding Neck Flange Super Duplex Stainless Steel A182 F51 / UNS S31803

Super Duplex Stainless Steel A182 F51/UNS S31803 Welding-Neck Flange Raised Face with Smooth Finish


Flanges are used when the piping joint needs dismantling. These are used mainly at equipment’s, valves and specialties. In certain pipelines where maintenance is a regular feature, breakout flanges are provided at definite intervals. A flanged joint is composed of three separate and independent although interrelated components; the flanges, the gaskets and the bolting. Special controls are required in the selection and application of all these elements to attain a leak-proof joint.

Flanges can be classified based on the method of attachment to the piping as below: Welding-Neck, Slip-on, Blind, Threaded, Socket-Weld, Flat, Lap-Joint, Reducing Flange
