Double-sided Submerged Arc Welding Spiral Steel Pipe is a type of steel pipe made from steel strip. It is spiral-formed in a forming machine and then continuously welded together using double-sided submerged arc welding technology. This steel pipe has a simple production process and low operating costs. It is widely used in medium- and large-diameter low-pressure water pipes, thermal pipes, and piling pipes. It is also one of the main pipe types used in long-distance oil and gas pipeline projects in my country.
Product Features
Double-sided Submerged Arc Welding Spiral Steel Pipe is produced by feeding the steel strip into a pipe welding unit. After multiple rolling passes, the strip is gradually rolled up to form a round pipe blank with an open gap. The reduction of the extrusion rollers is adjusted to maintain a weld gap of 1-3mm and a flush weld. Spiral welded pipe is produced in various specifications by spirally forming the raw steel strip in a forming machine and then using internal and external submerged arc welding. The double-sided submerged arc spiral welded steel pipe has a simple production process and low operating costs. It has the advantage of low-cost operation and price advantages in the markets of medium and large diameter low-pressure water pipes, thermal pipes and piling pipes.

Double-sided Submerged Arc Welding Spiral Steel Pipe for pressure fluid transportation (SY5036-83) is primarily used in oil and natural gas pipelines; spiral seam high-frequency welded steel pipe for pressure fluid transportation (SY5038-83) is welded using high-frequency lap welding and is used for pressure fluid transportation. Double-sided submerged arc welded pipes for pressure fluid transportation should be welded using high-frequency lap welding. A certain passage should be left between stacks of double-sided submerged arc welded pipes. The width of the inspection passage is generally around 0.5m, and the width of the access passage is generally 1.5 to 2m, depending on the material size and transportation machinery.
Double-sided Submerged Arc Welding Spiral Steel Pipes are made by continuously welding narrow strip (sheet) coils using double-sided submerged arc spiral welding technology. They have been widely used in long-distance oil and gas pipeline projects in my country, such as the West-East Gas Pipeline, and are the primary pipe type used in these projects.
