This extrusion line is our successfully-developed product by introducing overseas advanced technology combined with our country situation. This line is used to produce PVC steel wire reinforced soft pipes, and the pipe wall is PVC soft material, inside is spiral steel wire. This kind of pipe is characterized by pressure resistance, corrosion resistance, anlistatig, high-voltage endurance, excellent circulation ability, etc. So the final products of this line are applied to conveying air or gas, which is high- pressure and flammable, also used in the heavily-sucked, lightly-excluded of liquid impurity, and widely used in such areas as mechanism, chemical laboratory, architecture, agricultural irrigation, vacuum equipment and dust collector soft pipes, etc. Moulding machine adopts two motors to drive separately the moulding and conveying of steel -winding. Special screw design ensures the plasticization effect of PVC granules; precise heating and air cooling system ensures the PVC production technology; also equipped with stainless steel water troughs, flat-belt hauling-off unit.
