Product description

Double-Sided Submerged Arc Welded Spiral Pipe is a type of steel pipe manufactured using the submerged arc welding process, featuring a single spiral seam. It is produced on the most advanced continuous flying-welding production line in China, equipped with imported internal and external welding machines. The technology is highly sophisticated, with double-sided submerged arc automatic welding for both the interior and exterior surfaces. Each production line is equipped with a hydraulic tester, an advanced ultrasonic full-body material and seam automatic inspection system, and an X-ray real-time imaging inspection system. It also features a national-level CNAS laboratory.

Customer challenge

Prone to defects

The front-swing production line requires frequent stoppages for butt welding, resulting in low efficiency and a higher likelihood of defects.

The demand for the products increases.

There is an increasing demand for large-diameter, high-grade steel pipes with thick walls.

Have a short lifespan

Traditional pipeline materials often cause environmental pollution. For example, plastic pipe waste is difficult to dispose of.

It is easy to pollute the environment.

Traditional fluid pipelines often have a short service life and cannot guarantee quality.

Product function

Dredging and Slurry Conveyance

Structural Function

Fluid Transportation Function

Used for mud discharge and sand pumping, as well as for conveying grout in tunnels.

Used as steel pipes for structural applications, such as pile pipes, steel casings, structural steel pipes for construction, and support (column) pipes.

Used as pipelines for conveying gases and liquids, including petroleum, natural gas, steam, air, and water.

Value advantage

High Production Efficiency

The use of advanced double-sided submerged arc welding technology significantly enhances the efficiency of mass production, thereby reducing the manufacturing cost per unit.
High Material Utilization

Compared to straight seam welded pipes, spiral welded pipes can more effectively utilize raw materials under the same conditions, reducing waste and lowering material costs.
Stable and Reliable Quality

Good welding quality and durability reduce maintenance and replacement costs caused by quality issues, resulting in high cost-effectiveness over long-term use.
Diverse Specifications

Double-sided submerged arc welded spiral pipes can be customized in different diameters, wall thicknesses, and lengths according to customer needs, meeting a variety of requirements while avoiding unnecessary resource waste.
Long Service Life

The service life of double-sided submerged arc welded spiral pipes can exceed 30 years.
