Spiral Steel Pipe (SSAW Pipe)
Spiral steel pipe, also known as SSAW spiral welded steel pipe, is a widely used carbon steel pipeline product for large-diameter engineering projects. It is manufactured from high-quality carbon steel coils through advanced double-sided submerged arc welding technology. Produced strictly in accordance with API 5L, ASTM A252, GB and EN international standards, the pipe features stable structure, uniform wall thickness and excellent overall rigidity.
Different from ordinary straight seam pipes, the spiral welding structure evenly disperses pressure and external force, greatly improving pressure resistance, bending resistance and seismic performance. Every pipe undergoes professional quality inspections, including hydrostatic pressure testing, X-ray flaw detection and dimensional accuracy testing, to ensure zero defects in welding quality and stable mechanical performance.
Our spiral steel pipes support complete specifications. The outer diameter ranges from 219mm to 3500mm, with various wall thickness options. Standard lengths are 6 meters to 18 meters, and customized sizes are available according to customer requirements. Multiple anti-corrosion treatments can be provided, such as 3PE, TPEP, epoxy coal tar coating and internal anti-corrosion painting, which effectively improve rust resistance, acid and alkali resistance, and extend service life under buried and humid environments.
This product is highly adaptable and suitable for various heavy-duty industrial and municipal projects. It is widely applied in oil and natural gas transmission, municipal water supply and drainage, sewage treatment engineering, bridge piling, road foundation construction, thermal power and chemical pipeline systems.
We support factory direct sales, bulk wholesale and customized processing. With reliable quality, reasonable price and fast delivery time, our spiral steel pipes have been exported to many countries and regions, winning long-term trust from global customers.
