Sell Large Caliber Hollow Wall Twine Pipe Production Line

Product Name: Large Caliber Hollow Wall Twine Pipe Production LinePlace of Origin: ChinaWe succeeded in researching large caliber hollow wall twin pipe production lines
on the foundation of absorbing and utilizing European technology. As a result, we've
acquired many national patents. The production line was designed using high
density polythene (PE) as its main material. The rectangular pipes are extruded
by 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 outside
wall is neat and smooth. This line outputs pipes in specifications ranging in
diameters of 400 to 2,200mm. According to different applications, the hardness degree
of ring is divided into four grades; maximum hardness of 16kN/sqm. Suitable
for the acidic alkali liquid below 10%, these kind of pipes have many great characteristics such as, corrosion resistance, light, easy to fix and long service
life of 50 years. These pipes can substitute pipes made of high consumption material
like cement, cast iron, porcelain and ceramic. They are widely used for sewers,
bridges, building, sports fields, mines and farms.
