Product Description

Butt welding flange refers to a flange with a neck and a pipe transition and butt welding connection with the pipeButt weldingflange is not easy to deformation, good sealing, wide application, have corresponding rigidity and elasticity of 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

Feature: high temperature and high pressure resistance, not easy to deformation,better sealing,etc.
