Spiral Steel Pipe or Spiral SAW Pipe is a type of welded steel pipe manufactured from steel sheets through the Submerged Arc Welding (SAW) process in a spiral form. In this method, the steel sheet is shaped into a spiral, and the weld seam is continuously formed at an angle to the pipe’s longitudinal axis.
The spiral manufacturing process allows pipes to be produced in various diameters and long lengths without the limitations common to straight seam pipes. This makes spiral steel pipes a popular choice for large-scale fluid transfer projects.
For projects with large pipe diameters, long routes, and cost-control requirements, selecting spiral steel pipes can optimize the design and execution of transmission lines. The selection must consider project-specific technical conditions, working pressure, fluid type, and operational requirements.
Applications of Spiral Steel Pipes
Due to their structural and economic advantages, spiral steel pipes are used in various projects, including:
- Water transmission lines and distribution networks
- Oil and gas transfer projects under specified working pressures
- Infrastructure and civil projects with large diameters
- Large-scale industrial fluid transfer lines
- Marine projects and water-related facilities
Standards and Technical Specifications
Spiral steel pipes supplied by Petro Tejarat Sahel Kish are provided according to project specifications and client requirements. They can comply with common international standards such as API, ASTM, and DIN. The choice of standard, steel grade, plate thickness, and pressure class directly affects the performance and safety of the pipeline.
When selecting spiral steel pipes, factors such as working pressure, fluid type, environmental conditions, installation method, and operational requirements must be carefully considered. This ensures stable performance and long service life throughout the operational period.
