• Before the raw materials are put into use, they undergo strict physical and chemical inspections to ensure quality from the source.
• The head and tail of the strip steel are welded using single/double wire submerged arc welding, and after forming, they are actively repaired for reliable welding.
• The electric contact pressure gauge regulates the lower oil cylinder of the conveyor to ensure the smooth operation of the strip steel.
• The molding method can be either external control or internal control roller type, with strong adaptability.
• The weld seam gap control device accurately adjusts the pipe diameter, misalignment, and weld seam gap.
• Air plasma cutting machine achieves fixed length cutting of steel pipes.
• The production line can operate continuously with high production efficiency, especially suitable for large-diameter pipes.
• The core forming equipment can flexibly produce multiple diameter pipes on the same production line by adjusting the inclination angle of the steel strip, with outstanding cost advantages.

The spiral welded pipes produced by this production line are widely used in high and low pressure fluid transportation, urban building pile pipes, industrial structural pipes, as well as power, heat, and gas transportation pipelines. They have excellent properties such as high strength, corrosion resistance, good sealing, and long service life.
