Spiral Steel Pipe

Spiral-welded steel pipes are seamless steel pipes that are formed by bending and deforming steel strips or plates into circular, square, or other shapes and then welded together, with a seam on the surface. They can be categorized by welding methods, such as arc welding, high-frequency or low-frequency resistance welding, gas welding, furnace welding, and Bondi pipes. They can also be classified by seam shape into straight seam and spiral seam pipes. Welded steel pipes are used in the oil and gas drilling industry and mechanical manufacturing. Furnace-welded pipes can be used for water and coal gas pipelines, while large-diameter straight seam pipes are used for high-pressure oil and gas transmission. Spiral seam pipes are used for oil and gas transmission, pile pipes, bridge piers, etc. Welded steel pipes are more cost-effective and have higher production efficiency than seamless steel pipes.
