Spiral Steel Pipe

Spiral-welded steel pipes are those made by bending and shaping steel strips or plates into circular, square, or other shapes and then welding them together, resulting in pipes with visible seams. They can be categorized by welding methods, such as arc welding pipes, high-frequency or low-frequency resistance-welded pipes, gas-welded pipes, furnace-welded pipes, and Bondi pipes. They can also be divided by seam shape into straight seam welded pipes and spiral seam welded pipes. Welded steel pipes are used in the oil and gas drilling industry, machinery manufacturing, and more. Furnace-welded pipes can be used for water and coal gas pipes, while large-diameter straight seam welded pipes are used for high-pressure oil and gas transmission. Spiral seam welded pipes are suitable for oil and gas transmission, pipe piles, pier piers, etc. Welded steel pipes are more cost-effective and have higher production efficiency compared to seamless steel pipes.
