Q235 flange

Q235 flange is a kind of pipe fitting, which refers to the flange with neck and transition of round pipe and butt welding connection with pipe

Q235 flange is a kind of pipe fitting. Butt welding flange, also known as split flange, refers to the flange with neck and pipe transition and butt welding connection with pipe. Flanges are components that connect pipes to each other and to the ends of pipes. There are holes in the flange, and the bolts make the two flanges closely connected. Butt welding flanges and their gaskets and fasteners are collectively referred to as flange joints. Flange joints are the main products of equipment and equipment parts, as well as the main products of pipe design, pipe fittings and valves

The application scope of Q235 flange

has corresponding requirements for rigidity and elasticity, is not easy to deform, has good sealing performance, and is widely used. Reasonable butt welding thinning transition. The distance between joints is large, and there is no temperature deformation after welding. The complex bell structure is applied to pipes with large pressure or temperature fluctuations or pipes with high temperature, high pressure and low temperature, generally used to connect pipes and valves with PN greater than 2.5MPa; It is also used to transport expensive flammable and explosive media in the pipeline

Q235 flange shall be marked according to nominal diameter, nominal pressure, sealing surface form code, designated steel pipe series code (designated metric pipe code is "Series 2", and unspecified British pipe) and standard number

Q235 flange has different production specifications in use and production. According to the corresponding specifications, the practical application value and effect of butt welding flange can be protected. Specifications of the Ministry of Chemical Industry and the Ministry of Machinery and Pressure Vessels. Large scale application of high-pressure butt welding flange: boiler, pressure vessel, petroleum, chemical industry, shipbuilding, pharmacy, metallurgy, machinery, food and other industries
