large-caliber and hollow-wall winding pipe extrusion line

Product Description

Presently, concrete pipe plays a major role in sewage pipe lines. But because of its chemical instability and leaky joint, it is considered as a main factor in environmental pollution. Casting iron pipes are not ideal products either for their high cost and inconvenient execution character. In recent years, plastic pipes are successfully found to be pleasant substitutes for concrete ones. However, the large caliber hollow-wall winding pipes are more popular. They have increasingly becoming substitutes of concrete and cast iron pipes. And obviously, they are enjoying a salable market.
