1.Double flat wall composite winding pipe

 Pairs of flat-wall steel-plastic composite winding pipes are polyethylene (PE) as the main raw materials, prefabricated into "T" plate with a strip wound in the tube forming machine and welding into the pipeline, while the galvanized steel strip tiedthe W steel band embedded in the slot between two strip, coated steel strip on the PE pipe outer wall of the third generation of new steel-plastic drain pipe.
