Raised Face Weld Neck Flange

Raised face weld neck flange is an industrial product characterized by the requirement that the joint surface of both flanges on the sealing surface be convex. According to different installation methods, convex welding flanges can be divided into convex welding flanges and convex flat flanges. According to different processes, convex surface welding flanges can be divided into cast convex surface welding flanges and forged convex surface welding flanges.

Raised face weld neck flange has the following characteristics:

1. Simple structure

2. Easy maintenance

3. Corrosion resistance, aging resistance, pressure resistance

4. Tensile strength, pollution-free, long service life

5. Advantages such as easy installation

Note1:Dimensions N1,N2and N3 are measured at the intersection of the hub draft angle and the back face of the flange.Note2:For d1 dimensions see document"Flange Facing Dimensions parameter table 

Raised face weld neck flange fittings have excellent comprehensive performance, so they are widely used in basic engineering such as chemical, construction, water supply, drainage, petroleum, light and heavy industries, refrigeration, sanitation, plumbing, fire protection, power, aerospace, shipbuilding, etc.
