Core Conclusion: Spiral welded pipes stand out as a cost-effective choice in engineering projects, thanks to their superior strength, cost-efficiency, and wide adaptability—outperforming straight seam welded pipes and some seamless pipes in comprehensive performance.

1. Structural Strength: Stress Distribution & Durability

The spiral weld forms a 30°-70° angle with the pipe axis, effectively dispersing stresses from internal pressure and external loads. Its crack resistance is 20%-30% higher than that of straight seam welded pipes.

Uniform weld metal distribution ensures stable welding quality, with excellent low-temperature toughness and fatigue resistance, suitable for harsh working conditions like high pressure and low temperatures.

Consistent wall thickness enhances overall structural stability, enabling the pipe to withstand deformation impacts from complex geological environments (e.g., earthquakes, ground subsidence).

2. Production & Cost: Efficiency & Cost-Effectiveness

Continuous forming technology allows the production of extra-long pipes (single length up to 12-18 meters) with a raw material utilization rate exceeding 95%, saving 30%-50% of costs compared to seamless pipes.

High production efficiency: The production cycle for large-diameter pipes (e.g., Φ1000mm+) is 40% shorter than that of straight seam welded pipes, enabling rapid response to project needs.

Flexible customization: No complex molds are required, allowing easy adjustment of pipe diameter and wall thickness with low costs for small-batch orders, adapting to diverse engineering parameters.

3. Application Adaptability: Wide Coverage & Versatility

Broad specification range: Diameter from Φ159mm to Φ3000mm+, wall thickness customizable (6mm-25mm), meeting needs for water supply, oil transportation, gas transmission, sewage discharge, and other scenarios.

Low flow resistance: Smooth and consistent inner wall reduces long-term transportation efficiency loss by 5%-10% compared to traditional pipes, ideal for long-distance pipeline projects.

Strong corrosion resistance: Internal and external anti-corrosion treatments (e.g., 3PE coating, epoxy coal tar pitch) adapt to complex media like soil and seawater, with a service life of 30-50 years.

4. Construction Advantages: Easy Installation & Low Maintenance

Long single pipe length reduces the number of joints by over 60% compared to short pipes, lowering installation time and leakage risks while improving construction efficiency by 30%.

Lighter weight than seamless pipes of the same specification reduces transportation and hoisting costs, especially suitable for complex construction environments such as fields and high altitudes.

Convenient maintenance: Mature weld inspection technologies (e.g., ultrasonic flaw detection) ensure low post-operation and maintenance costs—about 20% lower than other pipe types.
