Raised face weld neck flange is a kind of pipe fittings, which refers to a flange with a neck & a round pipe transition and connected with the pipe butt welding. The weld neck flange provides sufficient strength inside and outside to prevent leakage. Weld neck flange are suitable for pipelines with high pressure or temperature fluctuations or high-temperature, high-pressure and low-temperature pipelines, and are also used for pipelines that transport very expensive, flammable and explosive media. Weld neck flange is not easy to be deformed, tightly sealed and widely used, the nominal pressure PN is about 16MPa.

Standard with raised face weld neck flange
Carbon steel flanges are tight and reliable. It has two tightly sealed closed surfaces, and until now the materials of tightly sealed closed surfaces of ball valves are widely used with various molecular compound plastics, which have good tightness and can successfully achieve strict sealing. Since carbon steel flanges are wiping during opening and closing, they can be used in media with suspended solid particles. Commonly used processes: forging, casting, mid-plate rolling, mid-plate cutting, etc.

Benefit of weld neck flange :
1. The joint reception and pipeline can maintain the tight sealing performance of the pipeline.
2. Facilitate the replacement of a certain section of pipeline.
3. It is convenient to disassemble and check the material situation of the pipeline.
4.It is convenient to close a certain pipeline.
