Mini Diameter Spiral Welded Pipe

For applications demanding precision fluid conveyance, structural integrity in compact designs, and reliable performance in constrained spaces, small-diameter spiral welded pipes are the preferred engineering solution. Our range of high-quality Small Size Spiral Welded Pipe is engineered for durability and efficiency. We also offer versatile Small Bore Spiral Welded Tube options designed for specialized systems. When strength-to-size ratio is critical, our robust Small Caliber Spiral Steel Pipe provides an excellent balance. For the most space-sensitive installations, our precision-manufactured Narrow Diameter Spiral Welded Tube delivers uncompromised performance. Each product is manufactured using advanced spiral welding technology, ensuring superior seam strength and dimensional consistency compared to traditional longitudinal welded pipes.


The manufacturing process of our Mini Diameter Spiral Welded Pipe involves forming a continuous strip of steel into a spiral shape and welding the seam along the entire length. This method creates a pipe with a uniform, strong weld that distributes stress more evenly. Key technical parameters defining our product line include:

  • Outer Diameter (OD): Ranges from 20 mm (0.79 inches) to 150 mm (5.91 inches).
  • Wall Thickness: Available from 2.0 mm to 6.0 mm, depending on the diameter and required pressure rating.
  • Standard Length: Typically supplied in 6-meter or 12-meter lengths; custom lengths are available upon request.
  • Material Grades: Manufactured from carbon steel (ASTM A53, A106), low-alloy steel, or according to specific international standards (API, DIN, JIS).
  • Welding Process: Utilizes Submerged Arc Welding (SAW) for high-quality, consistent, and defect-free seams.
  • Surface Treatment: Options include black (mill finish), painted, galvanized, or coated with epoxy or polyethylene for corrosion protection.
  • Tolerances: Strict adherence to dimensional tolerances for outer diameter (±0.5% or as per standard), wall thickness (±10%), and straightness.

The following table provides a quick reference for standard specifications of our Mini Diameter Spiral Welded Pipe:

Nominal Bore (mm) Common Outer Diameter (mm) Standard Wall Thickness (mm) Approximate Weight (kg/m) Common Pressure Rating
25 33.7 2.5 - 3.2 1.9 - 2.4 Medium
50 60.3 2.8 - 3.6 4.0 - 5.0 Medium
80 88.9 3.2 - 4.0 6.8 - 8.4 Medium to High
100 114.3 3.6 - 4.5 9.8 - 12.2 Medium to High
150 168.3 4.0 - 6.0 16.2 - 24.0 High

These pipes undergo rigorous non-destructive testing (NDT), including ultrasonic testing and hydrostatic pressure tests, to ensure they meet or exceed industry standards for quality, safety, and longevity. Their primary applications include instrumentation lines, pneumatic conveying systems, structural components in furniture and machinery, irrigation systems, and various industrial process lines where space is limited but performance cannot be compromised.
