Spiral Steel Pipe 10

Spiral-welded steel pipes are those that are formed by bending and deforming steel strips or plates into circular, square, and other shapes, and then welded together, resulting in a longitudinally jointed surface. They can be categorized by welding methods such as arc welding, high-frequency or low-frequency resistance welding, gas welding, forge welding, and Bondi pipes. They can also be divided into straight seam welded pipes and spiral seam welded pipes based on the seam shape. Arc welded pipes are used in the oil and gas drilling industry and machinery manufacturing. Forge welding pipes can be used for water and coal gas pipelines, and 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, pipe piles, bridge piers, etc. Welded steel pipes are more cost-effective and have higher production efficiency than seamless steel pipes.
