Description

Technical Field

[0001] The utility model relates to the technical field of spiral steel pipe processing, and specifically relates to a spiral rolled steel pipe forming machine. Background Technique

[0002] Spiral steel pipes are spiral seam steel pipes made of strip steel coils as raw materials, formed by cold extrusion and welded by an automatic double-wire double-sided submerged arc welding process. The spiral steel pipe feeds the strip steel into the welded pipe unit, and after being rolled by multiple rolling mills, the strip steel gradually rolls up to form a circular pipe blank with an opening gap. Adjust the reduction of the extrusion roller to control the weld gap within 1-3 mm and make both ends of the weld flush. Spiral steel pipes are mainly used in water supply projects, petrochemical industries, chemical industries, power industries, agricultural irrigation, and urban construction.
