Flat welding flange connection is the two pipes, pipe fittings or equipment, first fixed on a flange, between the two flanges, plus flange pad, bolted together to complete the connection. Some pipe fittings and equipment have their own flanges, which are also flange connections. Flat welded flanges are divided into threaded connection (wire connection) flanges and welded flanges. Low pressure small diameter wire flange, high pressure and low pressure large diameter are welded flange, different pressure flange thickness and connection bolt diameter and number are different.

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.

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.

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.
