Embodiment Construction
[0006] The present invention will be further described in conjunction with the accompanying drawings, the plastic pipe extruded by the inner layer thin-walled plastic pipe extruder (1) through the rubber material extruder (2) in the front is painted on the plastic pipe by the glue coating device. The outer circular surface of the plastic pipe is cooled by the cooling tank (3) in front to harden the plastic pipe and remove it from the steel strip (6) supported on the coil support (3) by cleaning and drying equipment (5). After derusting, degreasing, etc., it enters the steel pipe forming mold combination device together. The steel strip is gradually rolled and squeezed by the roller rolling mold to form a steel pipe and tightly wrapped on the outer circle of the plastic pipe, and then the lap welded by the rolling welding machine (7) Live, the rubber material extruded by the outer layer plastic material extruder (10) is applied to the outer surface of the steel pipe through the ...
