Hubei farmland irrigation PE pipe, corrosion-resistant water pipeline

The farmland irrigation PE pipe introduced this time is a corrosion-resistant water pipeline extruded from polyethylene raw materials. It is a widely used water pipe category in the current agricultural irrigation field, and can be adapted to the water transportation needs of various farmland irrigation scenarios in Hubei. The conventional nominal diameter of this type of pipe covers 20mm-630mm, and the pressure grade covers 0.4MPa-1.6MPa, which can meet the requirements of irrigation projects with different heads and different water transportation scales. The appearance of the pipe is mostly black, and the outer wall can be added with blue marking lines on demand to distinguish the use of water transportation. The whole is non-toxic and tasteless, and will not cause pollution to irrigation water bodies. It meets the safety requirements of agricultural irrigation water bodies. Pipes and supporting pipe fittings of different diameters and different pressure grades can also be customized according to project needs to meet differentiated irrigation water transportation design requirements.

The core selling points mainly include the following four points:

First, it is resistant to corrosion and erosion, and is suitable for the characteristics of water and soil in Hubei. The soil of some cultivated land in Hubei is slightly acidic, and some irrigation areas will be mixed with matured farmhouse fertilizer aqueous solution, water-soluble fertilizer and other media during water transportation. Traditional metal pipes and cement pipes are prone to corrosion, scaling, perforation and other problems after long-term use. PE corrosion-resistant water transportation pipes can withstand common acid and alkali media, soil microorganisms and agricultural residue media erosion. There is no need for additional anti-corrosion treatment when buried in the ground. It is not easy to scale under normal use, and the water transportation performance will not decrease significantly with the increase of service life.

Second, the water delivery efficiency is high, and the installation and transportation are convenient. The inner wall of this type of PE pipe is smooth, and the roughness coefficient is only 0.008. Under the same diameter and pressure conditions, the water delivery flow is increased by 25% -30% compared with traditional cement pipes, and the water head loss is small, which can reduce the energy consumption cost of irrigation and pumping. At the same time, the weight of the pipe is only 1/8 of the steel pipe of the same specification, and it can be transported and laid without large lifting equipment. It is especially suitable for the regional characteristics of Hubei hills and mountains, which can greatly reduce the construction difficulty in complex terrain areas. The pipeline joint adopts hot melt socket or docking process, which has good sealing performance, which can reduce the problem of dripping during water delivery and improve the utilization rate of water resources.

Third, weather resistance and deformation resistance, suitable for Hubei climate conditions. Hubei has a subtropical monsoon climate, with extreme temperatures above 40 ° C in summer and -5 ° C in some mountainous areas in winter. Pipelines in irrigation areas along rivers and lakes are prone to short-term water immersion during flood season. This type of PE pipe has a brittle temperature of -70 ° C and a maximum working temperature of 60 ° C. It has good toughness and anti-deformation ability. It can withstand short-term temperature fluctuations, slight ground subsidence and frost heave. Short-term water immersion will not cause corrosion, deformation, cracking and other problems, and has strong environmental adaptability.

Fourth, the operation and maintenance cost is low, and the comprehensive use is cost-effective. The normal buried service life of this type of PE pipe can reach more than 20 years, which meets the life requirements of the irrigation pipe network for high-standard farmland construction. There is no need to regularly carry out operation and maintenance work such as anti-corrosion coating repair and pipeline dredging during use. Daily operation and maintenance only need to regularly check the sealing of joints and the running status of valves. The operation and maintenance workload and cost are much lower than traditional metal and cement pipes, and the comprehensive investment for long-term use is more advantageous.

The application scenarios of this type of corrosion-resistant water transportation PE pipe include: irrigation and water transportation of rice, wheat, rapeseed and other crops in the main grain-producing areas such as Jianghan Plain in Hubei Province; water diversion and irrigation of fruit and tea gardens and Chinese herbal medicine planting bases in hilly and mountainous areas such as western Hubei and northeastern Hubei; main branch pipe networks of greenhouses, drip irrigation and micro-spraying systems for characteristic planting in agricultural concentration areas such as southeastern Hubei; irrigation backbone and branch pipe network construction of various high-standard farmland construction projects; water pipeline laying of small farmland water conservancy projects, etc. Suitable groups include: construction units of high-standard farmland construction projects at all levels in Hubei Province, agricultural planting professional cooperatives, family farms, large-scale growers, operators of modern agricultural industrial parks, and contractors of small farmland water conservancy projects.

This type of corrosion-resistant water transmission PE pipe strictly implements the national standard of GB/T 13663 series "Polyethylene (PE) Pipeline System for Water Supply", which meets the relevant quality requirements of irrigation pipes in the "General Rules for High-standard Farmland Construction" of the Ministry of Agriculture and Rural Areas. All batches of products have undergone hydrostatic test, wall thickness deviation test, sealing test and other indicators before leaving the factory.
