Welded steel pipe slag is the slag that remains inside the weld. Theoretically, there are three main reasons for slag inclusion in submerged arc automatic welding seam: 1) There are many inclusions in the raw materials (including base metal, welding wire, and flux); 2) The interlayer cleaning is not

At present, the most common pipe cutting method for spiral steel pipe manufacturers is plasma cutting, which will generate a large amount of metal vapor, ozone, and nitrogen oxide smoke during cutting, which will seriously pollute the surrounding environment. The key to solving the root problem is h

The service life of the spiral welded pipe is related to the surface decarburization of the spiral welded pipe. If the surface is decarburized, the strength and wear resistance of the spiral welded pipe will be reduced, which will directly affect the service life of the spiral welded pipe. If the de

The connection method specification of galvanized steel pipe depends on the type of connection method. Generally, there are several types, such as flange connection, clamp groove connection, and welding. In the actual connection of galvanized steel pipes, welding is the most commonly used connection
1. To prevent erosion due to heating, the welding should not be too long, about 20% less than the carbon steel electrode, the arc should not be too long, the layers are cooled quickly, and a narrow weld bead is appropriate.2. The hardening of stainless steel pipe fittings after welding is fast, whic
