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:How do the rubber tubes fit into the galvanized pipe?
- The inner diameter and outer diameter of the galvanized pipe must be determined.
- Q:What is a rubber core pulling method?
- The hose shall be filled with water or gas at a pressure of 0.5 0.8N / mm before pouring concrete. At this point, the hose diameter can be increased by about 3mm. When pouring concrete, the vibrating bar should not touch the hose, and should check the pressure of the water meter regularly. If there is any change, the pressure must be filled.Smoke tube longer than tube core pulling slightly later. Before the pipe is pumped, the water is lowered and the pipe section is reduced, and the pipe can be drawn away from the concrete. The order of pumping is usually first, then first, then first, then straight.
- Q:Hydraulic hose joint dimensions
- Classification of threadsThe 1. threaded internal and external threads two;2. according to the shape of teeth can be divided into: 1) triangular thread 2) trapezoidal thread 3) rectangular thread 4) sawtooth thread;3. by line, single, head and multi thread;4., according to the direction of rotation, two kinds of left and right threads, the right is not marked, left plus LH, such as M24 * 1.5LH;5. according to different uses are: metric common thread, thread sealed pipe thread, non threaded sealing pipe thread, 60 degrees taper pipe thread, metric taper thread, etc.
- Q:What material is the rubber joint used in the desulfurization pipeline? What's the difference?
- Three yuan EPDM rubber joint can be used, PN4-6 is no problem. Generally, the desulfurization pipeline is weak acid base,
- Q:What kinds of pipe joints can be divided into? What are the differences between the so-called one - piece pipe joint and other types of pipe joint?
- The pipe joint is divided into a steel pipe joint and a hose joint.The steel pipe joint is provided with a clamp sleeve type, a welding type, a clapboard is connected, a reducing connecting, an oil inlet connection, a combined connection, a pressure gauge connection, a flange connection, etc..A seizure type hose connector, removable, plug-in, you said one pipe joint is extruded hose connector, connector and sleeve is one, there is a separate.My side is to do this piece, the United States PARKER Parker hydraulic hose, joints, assembly, quick change connector.
- Q:What is the function of the rubber pipe joint and the installation pipe?
- The action of the rubber pipe joint on the installation of pipes:1. Small size, light weight, good elasticity, easy installation and maintenance.2. After installation, the transverse, axial and angular displacement of the pipe vibration can be absorbed. The pipe is not concentric and the flange is not parallel.3 、 after installation, it can reduce the noise caused by vibration of pipes, pumps and so on, and has strong vibration absorption ability.
- Q:The difference between hose and rubber tube
- Silicone tube: also known as silicone tube. Used as liquid, gas, and other materials to circulate and coat carriers.Latex tube: latex tube is made of latex material of different thickness of tubes, mainly used in hospitals, equipment factories, power plants, research laboratories and other fields, but also related to bungee jumping, trampoline and other places of entertainment.
- Q:How can I remove all the flavor on the rubber hose?
- The rubber itself is tasteless, and the smell of the rubber we smell is the flavor of a vulcanizing agent or accelerant.Cover or dry.
- Q:What are the pipes in the air conditioner?
- General automotive air conditioning system as part of the pipeline has 4 roots. Double steam system or bus to a little more.
- Q:Will the electric water heater be well connected with metal hose or hose?
- On the other hand, the utility model can effectively avoid the frequent switch of the water heater power switch because of the two grounding. Therefore, the metal pipe connection does not meet the safety and installation specifications.
