Spiral welded steel pipe refers to a steel pipe made by bending steel strips or plates into a round shape and then welding them together, with a spiral seam on the surface. Spiral steel pipes can be used for water transportation, steam transportation, oil transportation, pipe piles, bridge piers, etc. Spiral welded steel pipes have lower costs and higher production efficiency than seamless steel pipes.

Our company has introduced advanced domestic spiral steel pipe units, which can achieve automatic online adjustment, double wire double-sided welding equipment, and produce pipe diameters ranging from 219 to 3620mm. The equipment adopts automatic control technology and infrared laser imaging technology to achieve automatic adjustment of welding joints at any time. It uses X-ray imaging, complete physical and chemical experimental equipment, universal material testing machine, and ultrasonic flaw detector to ensure the product quality of spiral welded steel pipes.
