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.

flange (flange) connection is the two pipes, fittings or equipment, first fixed in a flange 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. Flange connection is an important connection mode in pipeline construction. The flange connection is easy to use and can withstand greater pressure. In industrial pipes, in the home, the pipe diameter is small, and it is low pressure, and the flange connection is not visible.

Reducing flange (also known as large and small flange) is a flange connected to a standard flange, but the nominal diameter of the pipe is smaller than the nominal diameter of the standard flange. Full-face flange: The sealing surface and the entire flange surface are in the same plane.Boss surface flange: The sealing surface is slightly higher than the entire flange surface. Concave and convex surface flanges: A pair of flanges, the sealing surfaces of which are concave and convex.Tongue and groove face flange: A pair of flanges have a sealing surface, one with a tenon and the other

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.
