Socket flanges are a type of connecting pipe fitting, which are formed by inserting the end of a pipe into a flange ring ladder and welding it to the pipe end and outer side. Depending on whether there is a neck, socket flanges are divided into two types: with and without a neck.Socket flanges are mainly used for pipe connection. Due to their structural characteristics, they have good rigidity and sealing performance and can be used in applications with pressures ranging from 1.0 to 10.0 MPa.

Butt welded flange is generally made by forging or forging rolling process. When the steel plate or section steel is used, the following requirements must be met: 1, welding flange should be ultrasonic detection, no delamination defects; 2. It should be cut into strips along the rolling direction of the steel, bent and welded into a ring, and make the surface of the steel form a cylinder of the ring. The steel plate shall not be machined directly into a neck butt welding flange; 3, the butt weld of the ring should adopt full penetration weld; 4.

Flange is a disk-shaped part, z is common in pipeline engineering, flanges are used in pairs. In pipeline engineering, the flange is mainly used for pipeline connection. In the pipeline that needs to be connected, a variety of installation of a piece of flange, low-pressure pipeline can use silk flange, more than 4 kilograms of pressure use welding flange. The gasket is added between the two pieces of flanges, and then tightened with bolts.
Carbon steel flanges are precise in shape and size, with low machining and low cost. However, cast flanges will have holes, cracks and impurities, and the internal structure of the casting is poor. The advantage is that it can have more complex shapes and be produced at low cost. Plain carbon steel flanges are less susceptible to rust and have a denser structure because they have a lower carbon content than cast flanges. They can withstand shear and tensile forces better and have better mechanical properties than forged flanges.
