Product Description

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
