Spiral Steel Pipe 13

Spiral-welded steel pipes refer to steel pipes with seams that are produced by bending steel strips or plates into circular, square, or other shapes and then焊接. They can be categorized into various types based on the welding method, such as arc-welded pipes, high-frequency or low-frequency resistance-welded pipes, gas-welded pipes, forge-welded pipes, and Bonde pipes. According to the seam shape, they are divided into straight seam-welded pipes and spiral seam-welded pipes. Electric welded pipes are used in the oil and gas drilling and machinery manufacturing industries. Forge-welded pipes can be used for water and coal gas pipelines, while large-diameter straight seam-welded pipes are used for high-pressure oil and gas transportation. Spiral seam-welded pipes are used for oil and gas transportation, pile pipes, pier piers, and more. Welded steel pipes are more cost-effective and have higher production efficiency than seamless steel pipes.
