First, the core requirements of precision steel pipes for hydraulic system cylinders.Hydraulic cylinders operate in harsh environments, requiring them to withstand the impact of high-pressure hydraulic oil for extended periods, as well as the high-frequency friction between the piston and the cylind

Currently, there are increasingly more types of straight seam steel pipes. With the rapid development of strip steel continuous rolling production and the advancement of welding and inspection technologies, weld quality is constantly improving, and the variety and specifications of welded steel pipe

First, what is the continuous rolling process for straight seam steel pipes?The continuous rolling process is used for the continuous rolling and diameter reduction of steel pipes. Continuous rolling is a process in which the steel pipe and mandrel move together in multiple stands. The deformation a

Heat treatment effectively improves the impact toughness, tensile strength, and rupture resistance of oil casing, ensuring its excellent performance in use. Oil casing is an essential steel pipe for drilling oil and natural gas, requiring good performance during use. Different temperature controls a
