Information

What is a butt weld flange? Butt welding flanges include long neck butt weld flanges, flanges with neck butt welds, neck weld flanges, etc. It is mainly suitable for the butt welding of flanges and pipes. Its structure is reasonable and its strength is It has high rigidity, can withstand high temperature, high pressure and repeated bending and temperature fluctuation; and its sealing performance is reliable. The butt welding flange with nominal pressure of 0.25~2.5MPa adopts concave and convex sealing surface.

 

In general, a butt weld flange is a flange with a neck that has a transition of a round tube and is butt welded to the tube. Butt welding flange is one of the flanged pipe fittings. It is widely used and popularized in different fields and industries. It has different scopes for use in use, and the environment to be used is different. It needs to be used according to certain conditions. .

 

The welded flange is suitable for steel pipe connections with a nominal pressure not exceeding 2.5 MPa. It plays an important role and value in the link of the pipe, but the nominal pressure must be guaranteed to be within a certain range. The sealing surface of the welding flange can be made into three types: smooth, concave-convex and grooved. The smooth-type butt-welding flange is the most widely used, especially when the medium condition is moderate, such as low-pressure non-purified compressed air. Low pressure circulating water, its advantage is that the price is relatively cheap. Butt weld flanges are suitable for pipelines with high pressure or temperature fluctuations or for high temperature, high pressure and low temperature pipelines, as well as for pipelines that are expensive, flammable and explosive.

 

At present, the welding flange has a wide range of use and promotion in the pipe fittings, because the scope of application and the environment of use are different, therefore, it is necessary to use according to the corresponding methods and methods.

 

The forging process of the butt flange is generally composed of the following steps, namely, selection of excellent billet blanking, heating, forming, and post-forging cooling. Forging processes include free forging, die forging and film forging. At the time of production, according to the size of the forgings, the number of production batches is chosen differently.

 

Butt welding flanges are often used in environments where medium conditions are moderate, such as low pressure non-purified compressed air and low pressure circulating water. Its advantage is that the price comparison is cheap. The sealing surface of the welding flange can be divided into three types: smooth, concave and convex and grooved. The application of smooth butt weld flanges is very wide, and the other two types of butt weld flanges are also more in use. The welded flange has a reasonable structure, high strength and rigidity, and can withstand various harsh environments such as high temperature and high pressure, repeated bending and temperature fluctuation, and does not degrade the sealing performance.
