Introduction to Spiral Pipe Products
Spiral pipe, also known as spiral welded steel pipe, is a type of steel pipe produced by winding a strip of low-carbon structural steel or low-alloy structural steel into a pipe billet at a certain spiral angle (called the forming angle), and then welding the pipe seam. This type of steel pipe can produce large-diameter pipes using narrower strips and has a wide range of applications.

This type of steel pipe can produce large-diameter pipes using narrower strips and has a wide range of applications.
Common Specifications of the Product
The diameter range of spiral pipes is quite wide, with common outer diameters (caliber) generally starting from 219mm, including 273mm, 325mm, 377mm, 426mm, 529mm, 630mm, 720mm, 820mm, 920mm, 1020mm, 1220mm, and many other specifications. Common wall thicknesses include 6mm, 7mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, etc. These specifications are widely used in water transmission pipelines, oil and gas transmission pipelines, and other engineering projects.
Product Applications
Due to its high strength, corrosion resistance, long lifespan, and strong adaptability, spiral pipe is widely used in multiple fields:
- Oil and Gas Industry: For long-distance transportation of oil and gas, as well as gathering and transmission pipelines in oilfields and gas fields.
- Energy and Power: For cooling water systems in thermal power plants, steam and flue gas emission systems, etc.
- Civil Engineering: As materials for foundation pit support, shoreline protection engineering, geological exploration, and other fields, with good compressive strength and stability.
- Infrastructure Projects: Applied in urban drainage systems, wastewater treatment plants, water supply engineering, and other infrastructure construction.
- Pressure Vessels: Used in the manufacture of pressure vessels such as boilers and reactors, capable of withstanding high temperatures and pressures.
- Transportation: As drainage pipes for bridges, tunnels, subways, underground passages, etc., and as drainage pipes and lining for tunnels, bridges, and culverts in highway and railway construction.
Product Advantages
Spiral pipes have the following significant advantages:
- High Strength: Spiral steel pipes have high strength and rigidity, capable of bearing large pressures and loads.
- Corrosion Resistance: Depending on the usage environment, spiral steel pipes can undergo different corrosion protection treatments, such as galvanizing and coating, to improve their corrosion resistance.
- Long Lifespan: Quality spiral steel pipes have a long service life and can operate stably in harsh environments for a long time.
- Strong Adaptability: Spiral steel pipes can be customized into different sizes and shapes to meet various engineering needs.
- Convenient Connection: Spiral steel pipes are usually connected by welding or flanges, with easy installation and high construction efficiency.
- Cost-Effective: Compared to other types of steel pipes, spiral steel pipes have lower production costs and higher cost-effectiveness.
