Spiral Welded Pipe: Comprehensive Guide for 2025

Overview of Spiral Welded Pipe

Spiral welded pipes, also known as Helical Submerged Arc Welded (HSAW) pipes, are widely used in industries such as oil & gas, water transmission, structural applications, and marine projects. These pipes are manufactured by rolling a steel plate into a cylindrical shape and welding the edges in a continuous spiral pattern.

Compared to seamless and longitudinal submerged arc welded (LSAW) pipes, spiral welded pipes offer cost-effectiveness, large diameter capability, and high strength, making them a preferred choice for long-distance pipelines.

Leading manufacturers like Cangzhou Spiral Steel Pipes Group Co., Ltd specialize in the production of high-quality spiral welded pipes, ensuring compliance with API Spec 5L, GB/T9711-2017, and SY/T5037-2018 standards. With 27+ years of experience, the company is known for precision manufacturing, strict quality control, and global supply capabilities.

In this guide, we will explore manufacturing processes, specifications, pricing, applications, coating options, and key suppliers of spiral welded pipes.

Spiral Welded Pipe vs. Other Pipe Types: Key Differences

When choosing a pipeline for industrial applications, it’s important to compare spiral welded pipes with seamless pipes and LSAW pipes.

Comparison of Spiral Welded Pipe vs Other Pipe Types

Feature	Spiral Welded Pipe (HSAW)	Seamless Steel Pipe	LSAW Steel Pipe
Manufacturing Process	Spiral welding	No welding, seamless extrusion	Longitudinal welding
Strength	High due to spiral structure	Strong but size-limited	Stronger for large diameters
Corrosion Resistance	Good, can be improved with coatings	Moderate	Moderate
Cost	Cost-effective for large projects	Expensive	Expensive for large diameters
Best Applications	Oil, gas, water, construction	High-pressure applications	Offshore, structural projects

Spiral welded pipes offer better cost efficiency, higher corrosion resistance, and larger diameter options compared to seamless and LSAW pipes.
