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.

- The valve chamber of the engine cylinder head cover counterclockwise with 8~10 open wrench counterclockwise unscrew rocker screw. Place the piston at the top dead center, turn the rocker head wire clockwise until the hand can not be moved, then back half a circle, then lock the nut.
- Q: What is the essential difference between rubber expansion joint and rubber joint?
- A rubber joint is a hollow rubber product used for flexible connections between metal pipes. The flexible joint is also called soft rubber pipe joints, rubber joints, soft rubber joints, flexible joints, high-pressure rubber joints, rubber shock absorber etc.. It is divided into 3 kinds: flange type, fixed flange type and thread type by connection. The structure can be divided into single sphere, double sphere and curved sphere. A tubular rubber component is composed of inner and outer layers of rubber, cord and steel ring, which is vulcanized and molded and then combined with a metal flange or a parallel joint. This product can reduce vibration and noise, and can be compensated by thermal expansion and cold contraction due to temperature changes. It is widely used in various piping systems.
- Q: Is flexible rubber joint and telescopic device a kind of thing?
- Characteristics of rubber pipe telescopic device:First, small size, light weight, good elasticity, easy installation and maintenance.Two, the installation can produce axial, horizontal, angular and angular displacement, without the user pipe is not concentric, flange is not parallel restrictions.Three, vibration and noise reduction at work.Four, using a special synthetic rubber resistant to high temperature, acid and alkali resistance, oil resistance, chemical corrosion resistance is an ideal product pipeline.
- Q: Do the rubber joint and Y filter need flange connection?
- Rubber hose joints are usually externally threaded, and type Y filters are internally threaded and are directly connected to the same caliber.Flange connection also has ah, according to demand
- Q: Why should the water stop strip be joined by heat instead of superposition?
- Thermal connection is the safest and most reliable method of joint treatment, but it has certain requirements for technology.
- Q: The difference between the rubber pipe and PE pipe?
- Rubber tube, this product is a rubber tube products, with oil, acid, alkali, heat, pressure and other characteristics of the transmission and attract rubber hose. Most rubber tubes are non-toxic and environmentally friendly, but some of the higher demand oil and gas pipes add flame retardants to the rubber material. The flame retardants contain toxic and harmful substances which can have a slight effect on the human body and the atmosphere. Rubber tube and characteristics; physiological inertia, UV resistance, ozone resistance, resistance to high temperature (-80 to 300), high transparency, strong resilience, resistant to compression permanent deformation, oil resistance, impact resistance, acid and alkali resistance, wear resistance, flame resistance, voltage, conductive properties. Apply to supporting electrical appliances, electronics, furniture, equipment, toys, hardware, medical equipment, sporting goods, audio, lighting, machinery, automobiles, motorcycles, ships, aviation, and other fields.
- Q: Flex rubber joint installation skills, what are the materials of rubber soft joint?
- Specification for installation of flexible rubber joints:Flexible rubber joints, piping construction, it is necessary to make it in a natural situation, not artificial products in the equipment, artificial deformation of the goods. When the pipeline medium for acid, oil, high temperature and other special information, should be higher than the pipe pressure, a gear of the joint.
