304 Stainless Steel Neck Threaded Butt Welding Flange

304 stainless steel neck threaded butt welding flange

Butt welding flange is a type of pipe fitting, which refers to a flange with a neck and a circular pipe transition, and is connected to the pipe by butt welding.

Welding flanges are not easy to deform, have good sealing, and are widely used. They have corresponding rigidity and elasticity requirements and reasonable welding thinning transition. The distance between the welding junction and the joint surface is large, and the joint surface is not affected by welding temperature deformation. It adopts a relatively complex horn shaped structure and is suitable for pipelines with large pressure or temperature fluctuations, as well as pipelines with high temperature, high pressure, and low temperature. It is generally used for connecting pipelines and valves with PN greater than 2.5MPa; It is also used on pipelines for transporting expensive, flammable, and explosive media.
