Product Description:

Based on technical and economic conditions of rural areas,development of water pipelines for low-pressure conveyance should be the main measure agriclutural water-saving irrigation.Widely used in low-pressure water irrigation engineering, UPVC pipes for irrigation has characteristics such as light weight, long length, small water resistance, corrosion resistance, anti-aging, simple construction . As replacements of the traditional material,UPVC pipe has siginificant advantages on energy conservation, environmental protection, economy, and practicality. Thus,it is necessary toapply and develop UPVC pipes in agricultural irrigation.

PVC-U or UPVC   low pressure water  irrigation  pipe

UPVC pipes for Low-pressure water irrigation is a buried pipe with one-time extrusion, smooth and flat wall .
As specail irrigation pipes in agricultural farmlands or cultivated lands ,UPVC pipes are widely used in engineerings like agricultural water-saving irrigation ,farmland irrigation and drainage ,urban sewage,chemical corrosion transportation engineering , mining, metallurgy, electric power,and telecommunications etc.Its scope is as follows:
A. Elevation: less than 1000m
B. Ambient temperature: -20 ℃ -40 ℃
C. Water temperature: the maximum temperature does not exceed 45 ℃, the minimum temperature not lower than 0 ℃;
D. Soil: suitable for acidic, alkaline and other corrosive soils
E. operating temperature is 0 ℃ -45 ℃, the maximum allowable working pressure does not exceed the nominal pressure. maximum nominal pressure of pipes is 0.4Mpa.

as a low pressure water pipelines, PVC irrigation pipe also has characteristics:
1 good mechanical properties: strong rigidity, high ability to resist external forces, can not easily be external damage in the process of underground water irrigation.
2 smooth pipe wall , small flow resistance, no rust, no fouling, clogging and efficient delivery.
3 good corrosion resistance, stable performance; in the delivery of water injection ,fertilizer not only does not corrode, and does not destroy nutrients in fertilizer to ensure production needs of crops.
4 formulated with antioxidants and light stabilizers so pipe has excellent anti-aging properties, long-term light or buried to guarantee its performance, service life of 20 years to 50 years.
5 stable pipe performance, good hygiene performance ,does not affect the water quality, does not cause toxic crops, pollution-free.
6 pipe light weight, transportation, installation, and easy to use.
