Kunming, Yunnan HDPE Introduction to winding pipe:
Current domestic municipal sewage discharge Water pipe Most roads adopt cement Pipe, due to its unstable chemical properties, loose connection, easy leakage and environmental pollution, has become a major public hazard for modern urban residents. Cast iron pipes have been banned from use due to many disadvantages such as inconvenient construction and high construction costs.
In recent years Plastic pipe Materials have successfully replaced cement pipes, and the new large-diameter hollow wall winding pipe has attracted much attention. It is a replacement product for cement pipes and cast iron pipes. The product is made of high density polyethylene as the main raw material, which is wound and compounded by a thermoforming machine. Its internal and external walls are flat and smooth, and the specification is DN200-2200mm.
This kind of pipe has the advantages of corrosion resistance, light weight, compression resistance, harmless, green and environmental protection, simple installation, large flow capacity, long service life (50 years), etc.
It is widely used in the drainage and sewage pipelines of highways, municipal construction, residential quarters, sports fields, squares, mines, agricultural culverts, bridges and other fields. Pipe properties of DPE winding pipe:
Chemical resistance: not corroded by sewage, waste water and chemicals, and not corroded by decaying substances in soil.
Impact resistance: the pipe wall adopts "I-shaped" structure, which is impact resistant, pressure resistant, and does not break under the condition of foundation settlement. Moreover, it has strong resilience after deformation, and has good adaptability to any foundation.
Aging resistance: the pipes are usually black and can withstand direct sunlight during storage and construction.
Cold resistance: the pipe will not be cracked and expanded under - 80 ℃
Light weight: convenient for transportation and construction, 1/8 of the weight of cement pipe. Only excavators are needed for pipe burying, without large equipment.
Convenient connection: pipes can be connected outside the trench and lifted into the trench by crane. In the construction of urban drainage works, the required project time and cost can be reduced
Superior abrasion resistance: it is more abrasion resistant than steel pipe and cement pipe, and has strong transportation capacity of domestic water and waste slag. Excellent drainage circulation, smooth inside, reduce friction, and fast drainage speed.
Economy: low price of raw materials, low construction, management and maintenance costs.
Environmental impact: HDPE is a harmless raw material, harmless to the land, and completely renewable.
