Butt welding flange is two large diameter pipe connection device, usually two flange and number of the bolt, its plastic strength is low, after adding suitable amount of carbon becomes hard, plastic lower strength enhanced.Connection it may need to bear very high tensile, compression, torsion and shear strength.Butt welding flange conveniently, manufacture simple, low cost, widely used, but with poor rigidity, therefore shall not be used for supply and demand, flammable, explosive and high vacuum degree requirements of the chemical process piping systems and height, extremely dangerous situations.Sealing surface type plane and surface.Butt welding flange welding electrode consumption is much, can not stand high temperature, high pressure, repeated bending and temperature fluctuations.
