The main manufacturing methods for spiral steel pipes include the following steps:
Ready steel strip: Select the appropriate steel strip, with width determined by the diameter of the required steel pipe. Coiling: Roll the steel strip into a spiral shape for forming spiral steel pipes during welding. Welding: Weld the spiral steel strip together to form spiral steel pipes. Processing: Process the spiral steel pipes, including cutting, sanding, and cleaning, to achieve a smooth surface and the required dimensions and accuracy. Inspection: Inspect the spiral steel pipes to ensure they meet the relevant standard requirements. Packaging: Package the spiral steel pipes for transportation and storage. These steps are the main manufacturing methods for spiral steel pipes, though the specific process may vary between different manufacturers and spiral steel pipe specifications.
Sch 40 Spiral Steel Pipe, also known as double-sided submerged arc-welded pipe, typically refers to spiral steel pipes with diameters greater than 219mm and wall thicknesses greater than 6mm.
The production process of the spiral steel pipe on the rear wall includes the following steps:
Ready Steel Strip: Select the appropriate steel strip, width determined by the diameter of the required steel pipe. Coiling: Coil the steel strip into a spiral shape for welding to form spiral steel pipes. Welding: Use double-sided submerged arc welding to join the spiral steel strip, creating spiral steel pipes. Processing: Process the spiral steel pipes, including cutting, polishing, cleaning, etc., to achieve a smooth surface and the required dimensions and precision. Inspection: Inspect the finished spiral steel pipes, including dimensional, appearance, and non-destructive testing, to ensure compliance with relevant standards. Corrosion Protection: Perform corrosion protection as per customer requirements, including hot-dip galvanizing, epoxy resin coating, polyurethane coating, etc. Packaging: Package the spiral steel pipes for transportation and storage. Spiral steel pipes with a rear wall offer excellent structural stability and mechanical properties, widely used in municipal engineering, petrochemical, construction, and other fields. Their advantages include high strength, corrosion resistance, and ability to withstand high temperatures and pressures, making them suitable for various complex geographical and chemical environments.
