Din2634 Pn25 Welding Neck Flange

DIN2634 flange have two holes, can wear bolt, make the two flange tight even.Between the gasket seal.It is the connection of the two pipes, fittings or equipment, fixed on a flange, a first between the two German standard flange, and flange pad, bolt fastening together, complete the connection.According to the connection parts of flange and flange can be divided into the container.This product is mainly used in oil and gas pipeline engineering, the natural gas pipeline engineering, chemical plants, municipal engineering, sewage treatment, power plant, shipbuilding, pharmaceutical, dairy products, beer, beverage, water conservancy and other industries.DIN2634 flange will not produce corrosion, pitting, corrosion or wear and tear, play an important role and value in use, used in different industries and fields.

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.
