Use and characteristic: Our company successfully develops the hollow twines tube production line on the basis of fully absorbing and digesting the European technology, the tubing takes the high-density polyethylene as the main raw material,
After passing through the first extruding machine to squeeze out the rectangular pipe, it enters the twines shaper. At the same time the second extruding machine blows out the glue block, and then it extrusion bonds to become. Its inter and outer wall is smooth, specification is 200-2200mm. It can be divided into 4 ranks, according to the different use link rigidity, the highest may reach to 16KN/M2, can adapt acid and alkali liquid below 10%. This kind tubing has the merit of quality light, anti-corrosive, simple installment, high flow capacity, long life (for 50 years) and so on, may substitute the tubing made of high energy consumption material (cement, cast iron, ceramics etc.), it is widely used in the dumps pollutants pipeline on the field of highway, municipal administration construction, residential district, athletic field, square, mine, agriculture, culvert, bridge draining water, Technical parameter
