ANSI Welding Neck Flange

ANSI Welding Neck Flange is a flange with a neck and a round pipe transition that is connected to the pipe by butt welding.

Welding neck flange is not easily deformed and sealed well, has corresponding rigidity and elasticity requirements and reasonable butt welding thinning transition, the distance between the welding port and the joint surface is large, and the joint surface is free from welding temperature deformation. The welding method used for the connection between the flange and the pipe is butt welding, and the weld seam is similar to the welding of pipes and pipes. Generally, argon arc welding is used for the bottom of the pipe with a small diameter, and the cover is manually welded, and double-sided welding is used for the large pipe diameter. Welding neck flange WN is suitable for pipelines with large fluctuations in pressure or temperature or pipelines with high temperature, high pressure and low temperature, and also used for pipelines conveying petroleum, chemicals, flammable and explosive media.
