The spiral welded pipe unit produced by our company has two methods: front swing intermittent production and rear swing continuous production. The rear swing continuous spiral welded pipe production line is mainly used for producing pipes for transporting oil and natural gas. After years of practice, it has been proven that this unit has many advantages such as stable molding, high degree of automation, low energy consumption, and high production efficiency.

• Adopting double swing bridge technology, the swing is reasonable, saving space and improving production efficiency
• Conduct strict physical and chemical inspections on raw materials to ensure product quality
• Adopting advanced welding processes and equipment to ensure stable welding quality
• Adopting non-destructive testing techniques such as ultrasound and X-ray to ensure the quality of welds
• After a strict inspection system, it is ensured that the pipe production process is qualified before production can begin
• The Duoleke spiral welded pipe production line can meet the needs of different industries and provide customers with high-quality products and solutions.

The spiral welded pipe unit, with its efficient forming process and flexible adaptability, is widely used in high and low pressure fluid conveying pipes, urban construction pile pipes, industrial structural pipes, power/heat/gas pipelines, etc., providing efficient and high-quality pipeline solutions.

Our company can provide a high-performance series of supporting equipment, including high-precision fully automatic flat head chamfering machines, high reliability fully automatic steel pipe hydrostatic testing machines, high-sensitivity ultrasonic flaw detectors, and high-resolution X-ray steel pipe inspection systems.

These advanced equipment are seamlessly integrated with the core unit to jointly build an efficient, intelligent, and zero defect oriented steel pipe production loop, significantly improving product qualification rates and customer trust.
