Small Size Spiral Welded Pipe

For applications requiring reliable fluid or gas conveyance in constrained spaces, our Small Bore Spiral Welded Tube offers an exceptional solution. Engineered with precision, this product category is ideal for intricate systems where standard sizes are impractical. Similarly, our Small Caliber Spiral Steel Pipe provides robust performance for low-pressure pneumatic lines and certain structural frameworks. When project specifications demand the utmost in compact design, our Mini Diameter Spiral Welded Pipe delivers, ensuring consistent flow characteristics in a minimal footprint. For specialized mechanical or instrumentation applications, the Narrow Diameter Spiral Welded Tube is manufactured to exacting tolerances, guaranteeing fit and function in the most demanding installations.

The Small Size Spiral Welded Pipe is manufactured using a continuous helical weld formation process, which inherently provides superior strength and uniformity compared to longitudinal seams, especially in smaller diameters. This construction method results in a product with excellent dimensional consistency and a high strength-to-weight ratio, making it suitable for both static and dynamic load-bearing applications. The spiral weld distributes stress evenly around the circumference, significantly enhancing the pipe's resistance to pressure and external forces.

Our production adheres to stringent international standards, including ASTM, EN, and DIN specifications. Key technical parameters for our standard range are detailed below:

• Manufacturing Standard: ASTM A139, EN 10217-1, DIN 2458
• Common Steel Grades: Q235B, S235JR, S355JR, ASTM A36, API 5L Grade B
• Welding Process: Submerged Arc Welding (SAW) or High-Frequency Welding (HFW)
• End Finish: Plain End (PE), Beveled End (BE) as per standard preparation.
• Surface Treatment: Bare, Black Paint, Varnish, or Galvanized (upon request).
• Key Advantage: The spiral seam offers greater flexibility in producing a wide range of diameters from a single strip width, ensuring cost-effectiveness for specialized sizes.
