Carbon steel integral flange has high neck height and relatively thick wall thickness. In terms of application, the integral flange is the flange connected with the equipment. Integral flange is mostly used in equipment manufacturing and is hardly used in pipeline design.
Carbon steel integral flange is mainly used in boiler and pressure vessel, petroleum, chemical industry, shipbuilding, pharmacy, metallurgy, machinery, stamping elbow, food and other industries.
