Precision steel tube is a high-precision seamless steel tube material processed by cold drawing or hot rolling. Because the inner and outer walls of precision steel pipes have no oxide layer, high pressure without leakage, high precision, high smoothness, cold bending without deformation, flaring, f
The welding method of large-diameter steel pipes should be selected according to the material and wall thickness of large-diameter steel pipes. Because different welding methods have different arc heat and arc force, different welding methods have different characteristics.For example, tungsten arc
Summary of welded steel pipes on January 6: raw materials continue to support welded steel pipe prices stabilize and consolidateOn January 6, domestic welded steel pipe prices rarely adjusted. According to the monitoring data of Lange Steel Cloud Business Platform: The average price of 4-inch (3.75m
1. Choose suitable venues and warehouses(1) The site or warehouse for storing steel pipes should be located in a clean and well-drained place, away from factories and mines that produce harmful gases or dust. Weeds and all debris should be removed on the field, and the steel pipe should be kept clea
In the appearance of steel pipes, the difference between seamless steel pipes and welded steel pipes is that the inner wall of the welded pipe has welding ribs, while the seamless steel pipe does not. The pressure of seamless pipes is higher. Welded pipes are generally around 10 MPa. Now welded pipe
