SSAW (Spiral Submerged Arc Welded) Steel Pipes, also known as spiral welded pipes, are produced through a continuous spiral welding process using hot-rolled steel coils, followed by submerged arc welding for superior weld quality.

Spiral Welded Pipe Manufacturing Process
The raw materials of spiral steel pipe are strip steel coil, welding wire and welding flux. Before forming, the strip steel is leveled, trimmed, planed, surface cleaned, conveyed and pre-bent. A weld gap control device is used to ensure that the weld gap meets the welding requirements. The pipe diameter, misalignment and weld gap are strictly controlled. After cutting into single steel pipes, the first three steel pipes of each batch must undergo a strict first inspection system to check the mechanical properties, chemical composition, fusion status of the weld, surface quality of the steel pipe and non-destructive testing to ensure that the pipe making process is qualified before it can be officially put into production.
what is spiral welded pipe?
Spiral welded pipe: It is made by rolling low-carbon structural steel or low-alloy structural steel strip into a tube blank at a certain spiral angle (called forming angle), and then welding the tube seam. It can produce large-diameter steel pipes with narrow strip steel. Its specifications are expressed by outer diameter * wall thickness. The welded pipe should ensure that the water pressure test, tensile strength of the weld and cold bending performance meet the requirements.
Applications of Spiral Weld Pipe
Application: Spiral steel pipes are mainly used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction, and for liquid transportation such as water supply, drainage, and petroleum transportation. Used for gas transportation: coal gas, steam, liquefied petroleum gas, natural gas. Used for structural purposes: pile driving pipes, bridges, docks, roads, building structural pipes, etc.
SSAW Pipe VS LSAW Pipe
The production process of spiral steel pipe straight seam welded pipe is simple, with high production efficiency, low cost and rapid development. The strength of spiral welded pipe is generally higher than that of straight seam welded pipe. It can produce welded pipes with larger diameters with narrow billets, and can also produce welded pipes with different diameters with billets of the same width.
LSAW steel pipes have a wide range of finished product specifications, and the toughness, plasticity, uniformity and density of the weld are good. They have the advantages of large pipe diameter, thick pipe wall, high pressure resistance, low temperature resistance and strong corrosion resistance. When building high-strength, high-quality and long-distance oil and gas pipelines, most of the steel pipes required are large-diameter thick-walled straight seam submerged arc welded pipes.
