Overview of SSAW Pipe

SSAW pipes (Spiral Submerged Arc Welded Steel Pipe) are a marvel in the world of steel production. With their unique spiral welding process, they offer an efficient and cost-effective solution for transporting large quantities of oil and gas. These pipes are crafted using narrower sheets or hot rolled coils, significantly reducing production costs. Moreover, their ability to be produced in large diameters makes them ideal for transporting vast amounts of substances. When you choose SSAW pipes, you’re not just selecting a product; you’re opting for efficiency, durability, and a testament to innovative engineering.

SSAW Pipe Specifications

Our SSAW steel pipes are meticulously designed to meet the highest standards. Dimensions range typically from 20 inches to 80 inches (406mm to 2032mm) in diameter. The production procedures involve the tandem welding technique, ensuring the joining of inside and outside coil edges for a high-quality weld structure. We offer various steel grades tailored to your needs. Surface coatings include options such as Lightly oiled, Hot dip galvanized, Electro galvanized, Black, Bare, Varnish coating/Antirust oil, and Protective Coatings like Coal Tar Epoxy, Fusion Bond Epoxy, and 3-layers PE. Our pipes come with diverse end types, joint methods, and a range of machining services, ensuring that they fit seamlessly into your projects.

What is SSAW pipe Manufacturing Process?

The manufacturing process of SSAW pipes is a blend of precision and innovation. It begins with the formation of pipes by rolling and welding a steel strip in a helix or spiral direction, creating a weld seam in a spiral line. This spiral welding is achieved using the submerged arc method, which relies on the tandem welding technique. This technique ensures the joining of the trimmed and beveled coil edges, resulting in a high-quality weld structure. Special systems like the Thermatool Spiral Seam Annealing are employed, requiring the installation of custom-designed “shaped” inductors. Every step is meticulously executed to ensure that the final product stands as a testament to quality and durability.


What is the difference between SSAW pipe and LSAW pipe?

When it comes to SSAW and LSAW pipes, understanding the differences is crucial for making an informed decision. SSAW pipes are welded in a helix or spiral position, while LSAW pipes are welded longitudinally. This fundamental difference in welding direction affects their pressure-bearing capacity and manufacturing ease. LSAW pipes, being longitudinally welded, have a higher pressure resistance and are typically used for high-pressure services. In contrast, SSAW pipes, with their spiral weld, are more suited for low-pressure services. Additionally, LSAW pipes have better geometry accuracy, lesser welding line, and undergo a more rigorous testing process. While both types have their unique advantages, LSAW pipes generally have a slight edge in terms of quality and application. However, the choice between the two ultimately depends on your specific needs and the nature of your project.
