Specification

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.

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.
