The working principle of high-frequency welded pipe equipment
High-frequency welded pipe equipment mainly consists of uncoiler, straight head machine, active leveler, shear butt welder, storage sleeve, molding and sizing machine, computerized flying saw, milling head machine, hydrostatic tester, drop roller conveyor, flaw detection equipment, baler, high-frequency DC drag, and full line of electrical appliances.
High-frequency welded pipe equipment is to feed a certain specification of steel strip into the machine, through the forming rollers to make the steel strip curled into a billet, and then use high-frequency proximity effect and skin effect to make the pipe edge is quickly heated to the welding temperature, and in the extrusion roller extrusion pressure to complete the weld, and then cooled, calibrated and roughly straightened to become the required specifications of the steel pipe.
