What is the difference between welded steel pipe and welded spiral steel pipe
Welded steel pipes refer to steel pipes with seams on the surface that are welded by bending and deforming steel strips or steel plates into round, square, and other shapes. The blanks used for welded steel pipes are steel sheets or strips. Since the 1930s, with the rapid development of continuou...Read more -
Precautions for welding stainless steel pipe fittings
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, ...Read more -

The importance of anticorrosion of long-distance natural gas steel pipelines At this stage, both domestic and foreign, the demand for natural gas is gradually increasing, among which natural gas has become an irreplaceable and important energy source. In this case, the demand for natural gas w...Read more -
How to solve the deformation problem of spiral seam submerged arc welded steel pipe
The spiral seam submerged arc welded steel pipe rotates and starts to enter the soft formation. Under the action of the tri-cone, the drill bit first produces elastic shear deformation of the formation, and then it is removed under the pressure of the tri-cone. In the simulated environment, the s...Read more -
Three large diameter spiral steel pipe connection methods
The most common connection method for large-diameter spiral steel pipes is welding, but in some projects, threaded connections, flange connections, socket connections, and groove connections are often used. Welding, flange connection Welding and flange connection is traditional spiral steel pipe ...Read more -
Surface treatment method of anti-corrosion spiral steel pipe
1. The surface of the anti-corrosion spiral steel pipe is cleaned with solvent and emulsion, which can remove the organic matter on the surface of the spiral steel pipe, but it cannot remove the surface rust, oxide scale, welding flux, etc., so cleaning can only be used as an auxiliary means. 2. ...Read more -
