Steel Pipe Weld Neck Flange ASME B16.5 1″-80″ DN25-DN200
Picture
Product Introduction
The welding neck flange is also called neck flange, butt welding flange and long-neck flange;
The welding neck flange is used for butt welding of flange and pipe. Its structure is reasonable, its strength and rigidity are large, and it can withstand high temperature and high pressure, repeated bending and temperature fluctuation, and its sealing is reliable.
neck butt welding flange is classified according to the material of stainless steel flange.
Features
The technical parameters of welding neck flange shall be strictly controlled during production and welding to ensure that it can fully play its role and value in production and use.
Butt-welding flange is not easy to deform, sealed well, and widely used, with corresponding rigidity and elasticity requirements and reasonable butt welding thinning transition. The distance between the welded junction and the joint surface is large, and the joint surface is free from welding temperature deformation. It adopts a relatively complex trumpet shape structure, which is suitable for pipelines with large pressure or temperature fluctuations or high temperature, high pressure and low temperature pipelines. It is generally used for the connection of pipelines and valves with PN greater than 2.5MPa; It is also used in pipelines conveying expensive, flammable and explosive media.
