Galvanized Spiral Steel Pipe refers to steel pipes that have undergone anti-corrosion processing, effectively preventing or slowing down corrosion due to chemical or electrochemical reactions during transportation and use. Their surface is slightly rougher than that of cold galvanized square pipes, appearing silver white, and is easy to produce for water supply pipes and a few drips, especially at one end of the workpiece. The zinc layer on the galvanized spiral pipe is several times thicker than electroplated zinc, and its corrosion resistance is several times that of electroplated zinc.

It is particularly suitable for welding large-diameter spiral steel pipes, using continuous welding wire as the electrode and filler metal. During operation, a granular flux layer is covered over the welding area, making it especially well-suited for welding large-diameter spiral steel pipes.

The selection of galvanized spiral pipes now focuses more on the themes of design and technology, with quality being the core. When choosing seamless steel pipes, the overall construction quality should be the prime consideration.

Moreover, galvanized spiral steel pipes are frequently used in hydraulic engineering projects. They are an effective anticorrosive material against both chemical and electrochemical corrosion, suitable for applications in water supply, heating, gas supply, and drainage, offering high safety and reliability.

A spiral steel pipe with a rear wall is a type of steel pipe produced using double-sided submerged arc welding technology, typically referring 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:

Prepare 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 weld the spiral steel strip together to form spiral steel pipes. Processing: Process the spiral steel pipes, including cutting, polishing, cleaning, etc., to achieve a smooth surface and the required size and precision. Inspection: Inspect the finished spiral steel pipes, including size inspection, appearance inspection, non-destructive testing, etc., to ensure compliance with relevant standards. Corrosion Protection: Perform corrosion protection as per customer requirements, including hot-dipped galvanizing, epoxy resin coating, polyurethane coating, etc. Packaging: Package the spiral steel pipes for transportation and storage. Spiral steel pipes with rear walls offer excellent structural stability and mechanical properties and are widely used in municipal engineering, petrochemical, construction, and other fields. Their advantages include high strength, corrosion resistance, resistance to high temperature and pressure, etc., capable of withstanding various complex geographical and chemical environments.
