Correct operation of straight seam steel pipe
1. When the straight seam steel pipe is hung, the wire rope is not allowed to be pulled diagonally to prevent the wire rope from falling out of the groove. 2. Pay attention during operation to ensure personnel and equipment. 3. Frequently check the switches on the front and back of the trolley, a...Read more -
Quality inspection method of seamless steel pipe
1. Steel pipe geometry and shape inspection: ① Inspection of the bevel angle and blunt edge of the steel pipe end face: square, pallet. ②Steel tube curvature inspection: straightedge, level (1m), feeler gauge, thin wire to measure the curvature per meter, and the full-length curvature. ③ Steel pi...Read more -
Precautions for welding stainless steel pipe fitting
1. To prevent corrosion due to heating, the welding should not be too long, which is about 20% less than that of carbon steel electrodes. The arc should not be too long, and the layers will cool quickly. A narrow weld bead is preferred. 2. Stainless steel pipe fittings harden quickly after weldin...Read more -
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 -
