WELD NECK FLANGE01



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 fluctuations of the pipeline or high temperature, high pressure and low temperature pipeline, Generally used for PN greater than 2.5MPa pipe and valve connection;

Welding Neck Flange is flanges that designed to be joined to a piping system by butt welding. This kind of flange include lots of specification.

WN flange is generally made by forging or forging process. When the steel plate or section steel manufacturing, meet the following requirements: 1, butt welding flange should be ultrasonic inspection, no layered defects; 2. Should be cut into strips along the direction of steel rolling, welded into a ring through bending, and the surface of the steel to form a cylinder of the ring. Steel plate shall not be machined directly into neck butt welding flange; 3. The butt weld of the ring should adopt full penetration weld; 4. The butt weld of the ring shall be subjected to post-welding heat treatment, and X-ray or ultrasonic inspection shall be carried out, and X-ray inspection shall meet the II requirements of JB4730, and ultrasonic inspection shall meet the I requirements of JB4730.

3. The slope of the outer neck of the butt welding flange should not be greater than 70°. Welding flange in the production and welding of strict control of technical parameters, can play a full role in the production and use of value.

Neck butt welding flange is a kind of excellent engineering component, neck butt welding flange is used in the pipeline medium requirements of high occasions, the butt welding and flat welding process we use is mainly used to improve the welding stress, reduce the sealing surface deformation of a measure. However, the cost of raw materials with neck butt welding flange is higher, and the pressure of neck flat welding flange is lower than that of butt welding flange. With neck butt welding flange stiffness, high strength, not easy to leak.

Welding seams with neck butt flanges can be radiographed.The material of neck butt welding flange is usually machined from forged steel parts.
