The difference between fixed welding joints, rotating welding joints, and prefabricated welding joints in steel pipe welding
Fixed welding is a welding joint that cannot move after the steel pipe is assembled. During the welding process, the welding position changes (horizontally, vertically, upward, and inward). Rotating the welding port means rotating the welding port during the welding process so that the welder can...Read more -

Steel structure maintenance and upkeep
1. Regular rust and anti-corrosion protection Generally, the designed service life of steel structures is 50-70 years. During the use of steel structures, the chance of being damaged due to overload is very small. Most steel structure damage is caused by corrosion that reduces the mechanical and ...Read more -
Why use seamless tubes for gas pipelines?
Why use seamless tubes for gas pipelines? 1) Safety issues of gas pipelines Because gas is an explosive and combustible energy source, safety precautions must be followed when using it. Accidents can happen quickly if the pipeline quality is subpar or if the working environment poses safety risks...Read more
