Product Name: Large Caliber Hollow Wall Twine Pipe Production LinePlace of Origin: ChinaWe succeeded in researching large caliber hollow wall twin pipe production lineson the foundation of absorbing and utilizing European technology. As a result, we'veacquired many national patents. The production line was designed using highdensity polythene (PE) as its main material. The rectangular pipes are extrudedby an extruder and then enter into the twin forming machine. At the same time,the second extruder sprays the rubber and then squeezes to return it. Its outsidewall is neat and smooth. This line outputs pipes in specifications ranging indiameters of 400 to 2,200mm. According to different applications, the hardness degreeof ring is divided into four grades; maximum hardness of 16kN/sqm. Suitablefor the acidic alkali liquid below 10%, these kind of pipes have many great characteristics such as, corrosion resistance, light, easy to fix and long servicelife of 50 years. These pipes can substitute pipes made of high consumption materiallike cement, cast iron, porcelain and ceramic. They are widely used for sewers,bridges, building, sports fields, mines and farms.
