Integral flange is a kind of flange connection. It is also a kind of steel pipe flange with neck butt welding. Materials include carbon steel, stainless steel, alloy steel, etc. In various domestic standards, if is used to represent the integral flange. It is mostly used in pipelines with high pressure. The production process is generally casting. In flange type, an "if" is used to represent the type of integral flange. Generally, it is raised surface (RF). If it is used under the conditions of flammability, explosion, height and extreme harm, the sealing surface of convex concave surface (MFM) and tenon and groove surface (TG) other than RF surface can be selected. Installation of flanged valves. The flange surfaces of valves and piping shall be free of damage, scratches, etc., and shall be kept clean. Especially when the metal gasket (oval or octagonal section) is used, the groove of the flange shall be consistent with the gasket, and red lead shall be coated for matching research to ensure its good sealing condition. The perpendicularity between the flange surface on the piping and the centerline of the piping and the error of flange bolt hole shall be within the allowable range. The valve and piping center line shall be consistent before installation.
