SSAW steel pipes are made of strip steel coils as raw materials, extruded at constant temperature, and welded by the automatic double-wire double-sided submerged arc welding process. This innovative production technology ensures the highest levels of precision and durability, making our pipes ideal for groundwater line applications.
The heart of this spiral steel pipe is its unique spiral design. The strip steel is fed into the welded pipe device and gradually rolled up by multiple rollers to form a circular tube blank with an opening gap. It has the ability to adjust the reduction amount of the extrusion roller, and the weld gap can be controlled between 1-3mm to ensure a seamless and firm connection. Additionally, both ends of the welded joint are perfectly flush, providing a perfect finish.
SSAW steel pipes have several characteristics that differentiate them from traditional steel pipes. Its spiral structure has excellent strength and resistance to external forces, ensuring the safety and reliability of the water delivery system. In addition, the high-quality welding process ensures that the joints are leak-proof and prevent water seepage or contamination. With its sturdy construction and secure connections, this pipe ensures long-lasting performance and minimizes maintenance needs, making it a cost-effective solution for any groundwater line project.

a. The deoxidation method is designated as follows: FF: Fully killed steel containing nitrogen binding elements in amounts sufficient to bind available nitrogen (e.g. min. 0,020 % total Al or 0,015 % soluble Al). b. The maximum value for nitrogen does not apply if the chemical composition shows a minimum total Al content of 0,020 % with a minimum Al/N ratio of 2:1, or if sufficient other N-binding elements are present. The N-binding elements shall be recorded in the Inspection Document. |
