in the petrochemical industry , water transport channel , transporting oil & gas , medical industry etc , due to the transporting pipe corrosion problem cause big economic loss every year, in order to avoid the problem , the steel pipe coating plastic machinery come out at market demands . Xinda precision machinery Co., Ltd. adopt the advantage technology supply the quality steel pipe coating plastic machine , it can coat PE PPR ABS PSP plastic on the outside of the steel pipe , it produce various plastic-steel composite pipe has the high-strength steel pipe & both corrosion resistance character.

the plastic-steel composite pipe outside / inside surface coat with different plastic , like the PE PPR ABS PSP etc , the middle layer is the steel pipe , it make the plastic-steel composite pipe has advanced character of compression resistance , corrosion resistance , small flow resistance and long service life and non-toxic , it’s wide use in the gas & liquid transporting industry .

steel pipe pretreatment (acid washing / shot blasting) , then via the extrusion line to melt the plastic to coat on the steel surface , then cooling the coating layer via water tank for calibration . then via the hauling off machine to the cutter . it will cut them in the set length automatically .
