&#****8;&#****8; In order to meet the national need of municipal construction, our company developed heavy-caliber hollow wall-twining pipe production line successfully by directly introducing the whole set of advanced technique about hollow wall-twining pipe production line from the foreign country. This equipment adopts specially designed high-efficiency single screw extruder, and it has double-step decompressing screw, coupled with components of promoting mixing plasticization and high-efficiency compounding technique, so it can make up the disadvantage of national production line. The unique co-extruding technique pipe can be produced from over *0% retrievable material, which can save cost and not influence the quality.
