The pipe Expanding Machine is a special equipment for the spiral submerged arc welded pipe production line. It is used to expand the diameter of the pipe end of the spiral submerged arc welded pipe produced, so that the diameter and roundness of the pipe end within a certain length can reach the allowable range. 1220mm pipe Expanding Machine The maximum wall thickness of the expandable steel pipe is 12mm, the maximum diameter of the expandable steel pipe is φ529-φ1220 mm, and the maximum length of the steel pipe allowed to pass is 12500 mm. This machine is mainly used in spiral seam submerged arc welded pipe manufacturers. General specifications Expanding object: steel pipe Expanding way: mechanical Dia. Range: Φ500-φ1220 Wall thickness range: 4-12 Oil cylinder dia.: 400 Stroke: 400 Rated tension: 270 Rated oil pressure: 25 Pipe length: 8-12.5 Transitional length: 100 Orality: 0.6%D Expanding rate: 1.5%D Dia. D +2-0.5 mm Pipe requirement: 250 mm of pipe end is grinded, weld reinforcement is not bigger than 0.5 mm Layout: single end Total power: 100
