Overview of Spiral Welded Steel Pipe
A Spiral Welded Steel Pipe, also known as a Helical Submerged Arc Welded (HSAW) pipe, is manufactured by spirally winding a hot-rolled steel strip and welding the seam using submerged arc welding (SAW) methods. This process produces high-strength, large-diameter pipes ideal for oil & gas transportation, water transmission, piling, structural applications, and more.
Key Features of Spiral Welded Steel Pipe
✔ Large diameter capabilities (up to 3500mm)
✔ High strength and durability for industrial applications
✔ Cost-effective compared to seamless pipes
✔ Excellent weld integrity with submerged arc welding (SAW)
✔ Ideal for long-distance pipelines and structural projects
In this guide, we’ll explore everything about Spiral Welded Steel Pipes, including manufacturing processes, specifications, applications, price trends, and advantages.

Spiral Welded Steel Pipe Manufacturing Process & Quality Control
How Is Spiral Welded Steel Pipe Manufactured?
The Spiral Welded Pipe manufacturing process involves forming a continuous strip of steel into a spiral shape and welding the seam using submerged arc welding (SAW). This process is efficient, cost-effective, and ideal for large-diameter pipes. Below is a detailed breakdown of the step-by-step Spiral Welded Steel Pipe manufacturing process:
1. Steel Coil Selection & Preparation
- High-quality hot-rolled steel coils are selected based on the required specifications and standards.
- The steel strip is uncoiled, leveled, and trimmed to remove irregular edges.
2. Spiral Forming Process
- The steel strip is fed into a forming machine where it is rolled into a spiral shape.
- The edges are precisely aligned to ensure a consistent seam for welding.
3. Submerged Arc Welding (SAW) Process
- Internal and external submerged arc welding (SAW) is applied to create a strong, defect-free weld seam.
- The welding process involves flux protection, ensuring deep penetration and high strength.
4. Ultrasonic & Radiographic Testing
- Weld seams undergo ultrasonic and radiographic (X-ray) testing to detect any internal or external defects.
- Any defects found are repaired or rejected to ensure high-quality production.
5. Hydrostatic Testing
- Each pipe undergoes hydrostatic pressure testing to verify leak-proof performance under high pressure.
- Pipes that pass the test are certified for high-pressure applications.
6. Cutting & Beveling
- The pipes are cut to required lengths using automated cutting machines.
- The pipe ends are beveled to ensure proper welding during installation.
7. Coating & Anti-Corrosion Treatment
- Pipes can be coated with 3LPE, FBE, Epoxy Coal Tar, or Polyurethane coatings for enhanced corrosion resistance.
8. Final Inspection & Packaging
- Pipes are visually inspected, marked, and packed according to customer requirements.
- Each pipe is stamped with batch numbers, specifications, and manufacturer details for full traceability.
Why Spiral Welded Steel Pipes Are Preferred?
✔ Manufactured in large diameters, making them ideal for pipelines
✔ High-strength welding with internal and external SAW welding
✔ Cost-effective production compared to seamless or LSAW pipes
✔ Wide range of applications in oil, water, and structural projects
