Product Description
The spiral steel pipe is made of steel coils, extruded at room temperature, and welded by automatic double-wire double-sided submerged arc welding. The steel strip is fed into the welding pipe unit, and after multiple roller rolling, the steel strip is gradually rolled up to form a round tube with an open gap. The pressing amount of the extrusion roller is adjusted to control the weld gap to 1~3mm, and the two ends of the weld are flush.
