ANSI B16.5 Q235 Class 600 WN Flange

WN flange refers to a flange with a cone neck and butt welded with the cylinder or pipe. It is an integral flange. Its material has carbon steel, stainless steel and so on. Welding neck flange is a kind of pipe fitting, it refers to the flange with neck and a round pipe transition and butt welded with the pipe. Butt welding flange is not easy to deform, seal well, widely used, has the corresponding rigidity and elasticity requirements and reasonable butt welding thinning transition, welding distance from the joint surface is large, the joint surface is free from welding temperature deformation. Butt welding flange is not easy to deform, sealed well, widely used, has the corresponding rigidity and elasticity requirements and reasonable butt welding thinning transition, welding distance from the joint surface is large, the joint surface from welding temperature deformation, it takes a more complex cough body structure, suitable for pressure or temperature fluctuation…
