Large diameter spiral welded aluminum tube pipe
The maximum diameter of large diameter spiral welded pipes can reach 1580mm. Advanced low-temperature spiral welding production technology is used to weld narrow aluminum plates and strips into large diameter aluminum circular pipes through spiral welding. Flexible size, customizable according to user drawings.
The pressure of Chalco large-diameter spiral welding is designed to be 1.0MPa through the pipeline water injection pressure design of experiments. When the pressure reaches 5.1MPa, the welding seam is intact after blasting from the side of the middle section of the pipeline.
