Power Pipes <br /> Power pipes are made of PE (modified polyethylene) hot dip plastic or epoxy resin for internal and external coating, and have excellent corrosion resistance. At the same time, the coating itself has good electrical insulation and will not cause electrical corrosion. Low water absorption, high mechanical strength and small friction coefficient, can achieve the purpose of long-term use. It can also effectively prevent damage to plant roots and soil environmental stress.
Power tube (cable protection tube)
This product is a plastic product made from polyvinyl chloride resin as the main raw material, added with a suitable amount of additives, and extruded or injection molded. Mainly used in power cable protection systems. According to the trial data of the Ministry of Construction, the service life is 30-50 years, which is an ideal material for power cable protection.
Advantages of PVC-U power pipe
(1) Strong corrosion resistance, aging resistance, long-term use without rust, long service life, normal use up to 50 years;
(2) Self-extinguishing and flame retardant;
(3) The inner wall is smooth, the friction coefficient is low, and the cable is easy to pass through.
(4) Lightweight and slightly high;
(5) Flared socket or solvent bonding connection, easy installation, workload is only 1/2 of the steel pipe, low labor intensity and short construction cycle;
(6) Good electrical resistance and high safety in use;
(7) High cost performance;
Features of power pipes
1. Light weight: The density of CPVC is 1350-1500KG / M3, the weight is generally 1/10 of the same pressure pipe, 1/6 of the steel pipe, and the transportation and installation are convenient;
2. Convenient construction and significant economic benefits: CPVC high-voltage power pipe joints, waterproof seals, brackets and other components. The design is reasonable, the construction is convenient, and the concrete protective layer does not need to be poured. The combination of the brackets is a link, which shortens the construction period, has no radioactive carcinogens, and has significant economic and social benefits.
3. Excellent corrosion resistance: CPVC is resistant to acid, alkali, salt and other chemical solvents, and it will not crack in case of grease;
4. High strength, flame retardant, smoke suppression, heat resistance, long service life: CPVC high voltage power pipes completely overcome the shortcomings of poor weather resistance of ordinary PVC pipes. Its strength can replace steel pipe and overcome the phenomenon that the steel pipe is easy to corrode and the closed magnetic circuit causes the single core cable to be overheated and damaged; the flame retardant rating of CPVC pipe is FV-0. Index ≥40%, basically no heat transfer, linear expansion coefficient is 6.3 * 10-5CM / CM ℃ Vicat softening temperature ≥93 ℃, can be used at 105 ℃. Performance and price ratio are superior: CPVC pipe is slightly better than similar cement pressure pipes. Low, 20% lower than similar steel pipes, and the overall cost can be reduced by 15%.
5. Superior cost performance: CPVC pipes are slightly lower than similar cement pressure pipes, 20% lower than similar steel pipes, and the overall cost can be reduced by 15%.
Farmland irrigation pipeline water transfer skills have been developed rapidly in China's well irrigation districts in recent years due to their advantages such as water saving, energy saving, labor saving, small capital contribution, and good results. PVC
Farmland Irrigation Pipes <br /> Farmland irrigation pipes are more suitable for well irrigation districts in the plains of China, especially for the planting method of production responsibility system in China at this stage. With the increase of the state's investment in water conservancy equipment, a large number of PVC pipes have been laid in well irrigation districts to improve the water transfer coefficient.
