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.

- Q: Acid burette and burette why different structure
- Acid burette can be used frosted glass cock, convenient use, good sealing performance.
- Q: SolidWorks how do you put rubber hose on the iron pipe?
- It is important to note that different materials are assigned to each other: metal and rubber. To produce engineering drawings that guide production, fill in the corresponding section lines on the cutaway surface.
- Q: Can the high-pressure rubber hose be followed by water pipes? Will it be poisonous?
- The problem should also not large, if it is stored for a period of time in the yard, first put best water again, after all, is not a food container rubber material, inside some substances will dissolve gradually, and there is a water purifier water generating reaction of some harmful substances.
- Q: What's the difference between the rubber hose joint and the stainless steel hose joint?
- Rubber joints are widely used in chemical, construction, water supply, drainage, petroleum, light and heavy industries, freezing, sanitation, plumbing, fire fighting, power and other infrastructure projects. For example: with the pump, valve connection, vibration of the larger pipes, hot and cold changes frequently pipeline.No way, because it is loose summer, it is a well-known brand. Great. The general choice will definitely be good. Otherwise, all sorts of trouble in the later stage, it also can not stand.
- Q: What is the essential difference between natural rubber and three yuan ethylene propylene rubber?
- The strength of natural rubber in the elastic material, natural rubber, rubber, rubber, vulcanized rubber with higher intensity. The tensile strength of uncured rubber is called Green strength, and the Green strength of natural rubber is up to 1.4~2.5Mpa. The proper Green strength is necessary for rubber processing and forming. The tear strength of natural rubber is also higher, up to 98kN/m, and its abrasion resistance is better. The reason for the high mechanical strength of natural rubber is that it is self reinforcing rubber. When stretched, the macromolecule chains tend to form crystals in the direction of stress.
- Q: How to remove hose odor?
- When rubber is peculiar, it can be scrubbed by hydrogen peroxide. After drying, the odor will disappear. Or with waste tea sent to rubber products, tea has the role of adsorption odor.
- Q: Which is better for binding files with rubber tubes and cotton threads?
- X rubber hose and rubber band type light aging fast, not suitable for long-term preservation, cotton is afraid of water and insects
- Q: What are the properties of stainless steel metal hose materials?
- Stainless steel metal hose material is generally 304 stainless steel, the material of good ductility, flexibility, corrosion resistance, high temperature resistance.
- Q: How often do the oil - resistant rubber pipes undergo atmospheric pressure testing?
- Low temperature bending test at low temperature: hose clamp on rigid torsion wheel diameter hose diameter 12 times, for 6 hours at a low temperature, twisted 180 degrees within 12s when the measured torque and the standard temperature measured torque ratio. Low temperature bending: hose clamped in the diameter of the hose within 12 times the torsion wheel, parked at low temperatures for 24 hours, in the 10s to reverse 180 degrees, check whether or not the internal and external plastic brittle fracture and damage. Test of low temperature brittleness measurement hose is the most simple specimen should be bent 90 degrees at low temperature, or a hose after freezing compressed 1/2 to see whether the embrittlement, another method is to use a certain weight of the heavy hammer falls freely, to see if the specimen embrittlement impact specimen.
- Q: Difference and application of rubber joint and rubber expansion joint
- Rubber expansion joint is also called rubber joint, flexible rubber joints, rubber soft connection, soft joints, rubber expansion joint is formed by high temperature plastic rubber, rubber expansion joint and makes full use of the characteristics of rubber elasticity, high resistance, medium resistance etc..
