Application range of weld neck flange:

Weld neck flange has many features: not easy to deform, good sealing, wide application, have corresponding rigid, elastic demand and reasonable butt thinning transition, joint good distance away from the joint face the faying surface from welding deformation temperature, it take more complex syndromes beep form structure, suitable for pressure or temperature fluctuations of pipeline or high temperature, high pressure and low temperature pipes, Generally used for PN greater than 2.5mpa pipe and valve connection; It is also used to connect pipelines conveying expensive, flammable and explosive media.
