Product Description
Weld neck flange is a device that two large diameter pipelines connect each other,usually two flange piece and a number of fastening bolts, Welding neck flange is provided with good plastic property and low strength,and become hard after adding defined amount carbon element. Its connection is likely to need to withstand very high tensile, compression as well as torsion strength. Welding neck flange has the advantages of its convenience, simple manufacturing, low cost and wide use. But due to its poor stiffness, so it may not be used for flammable, explosive as well as extremely hazardous situations.There are two types of sealing faces:flat face and raised face. Welding neck flange needs to consume much welding rod can not afford the act of high temperature, repeated bending,high pressure as well as temperature fluctuation.
