High pressure butt-welded flanges

High-pressure butt-welded flanges are suitable for pipelines with high pressure or temperature fluctuations or for high-temperature, high-pressure and low-temperature pipelines, as well as for pipelines that are expensive, flammable, and explosive. The high-pressure butt-welding flange is not easy to be deformed, has good sealing and is widely used. The nominal pressure PN is about 16 MPa. […]

The difference between butt welding and flat welding in stainless steel flanges
