How to prevent decarburization of spiral welded steel pipes
The service life of spiral welded steel pipes is related to the surface decarburization of spiral welded steel pipes. If the surface is decarburized, the strength and wear resistance of the spiral welded steel pipe will be reduced, which will directly affect the service life of the spiral welded ...Read more -
Different types and appearance requirements of straight seam steel pipes
The high-frequency welding process of straight seam steel pipes is completed in high-frequency welded pipe units. High-frequency welded pipe units are usually composed of rolling forming, high-frequency welding, extrusion, cooling, sizing, flying saw cutting, and other components. The front end o...Read more -
Anti-rust maintenance and inspection methods for straight seam welded pipes
The production process of straight seam welded pipes is simple, with high production efficiency, low cost and rapid development. The strength of spiral welded pipes is generally higher than that of straight seam welded pipes. Narrower billets can be used to produce welded pipes with larger diamet...Read more -
The cooling form and construction introduction of large-diameter steel pipe
First, the cooling form of large-diameter steel pipe: Large-diameter steel pipe is a steel pipe with an outer diameter of more than 1000MM. Large-diameter seamless steel pipe is made of steel ingot or solid tube billet by perforation into the rough tube, and then hot-rolled, cold-rolled, or cold-...Read more -
Introduction to Rust Removal Technology of Submerged Arc Steel Pipe
In the process of anti-corrosion construction of oil and gas pipelines, the surface treatment of large-diameter submerged arc steel pipes is one of the key factors that determine the service life of pipeline anti-corrosion, which is the premise of whether the anti-corrosion layer and the large-di...Read more -
Deviation and forming method of the industrial large-diameter steel pipes in production
First, the deviation of large-diameter steel pipes in production: Common large-diameter steel pipe size range: outer diameter: 114mm-1440mm wall thickness: 4mm-30mm. Length: can be made into fixed length or unfixed length according to customer requirements. Large-diameter steel pipes are widely u...Read more
