PE steel mesh skeleton composite pipe for farmland irrigation

Core performance adaptation to farmland irrigation scenarios

Compared with traditional irrigation pipes such as ordinary PE solid-wall pipes and galvanized steel pipes, PE steel mesh skeleton composite pipes use steel mesh as the reinforced skeleton, taking into account the corrosion resistance of PE materials and the high pressure bearing of metal materials, and can be adapted to the water transportation needs of irrigation areas in different terrains. Its inner wall smoothness is much higher than that of metal pipes, and the water transportation resistance is small and not easy to scale. There will be no problems of pipe diameter narrowing and drip irrigation nozzle clogging after long-term use, and the water transportation efficiency can be improved by more than 15%. The pipe itself is acid and alkali resistant and soil corrosion resistant. It does not need additional anti-corrosion treatment for buried use. It has excellent low temperature resistance. There will be no brittle cracking problem in the low temperature environment in the northern winter. It is suitable for the irrigation environment of farmland in most regions of our country.

Precautions for the selection of farmland irrigation pipelines

Before selecting the type, it is first necessary to clarify the water pressure requirements of the irrigation area. Pipes with a pressure level of 1.0MPa can be selected in plain artesian irrigation areas. In hilly irrigation areas and areas with large height differences, the pressure level should be increased to 1.6MPa and above to avoid the problem of pipe bursting due to pressure overload. Secondly, the corresponding pipe diameter should be matched according to the designed water flow rate to avoid the waste of procurement costs caused by insufficient water delivery and excessive pipe diameter due to too small pipe diameter. Preference should be given to qualified products with uniform wall thickness and no obvious bubble dents. Do not choose non-standard products with substandard wall thickness for cost reduction. The subsequent operation and maintenance costs will increase significantly.

Key points of field construction and operation and maintenance

Before construction, the sharp stones and hard objects in the trench should be cleaned up in advance to avoid scratching the outer wall of the pipe during laying and affecting the service life. When hot melt connection, the heating temperature and docking time should be strictly controlled according to the specifications to avoid the leakage of the interface caused by virtual welding. When laying in the buried ground, a settlement allowance of about 1% should be reserved to avoid soil settlement pulling the pipe interface. Do not forcibly bend the pipe during winter construction to avoid dark cracks. Daily operation and maintenance check the interface and open pipe section every six months. If there is leakage, repair it in time. The service life of the pipe can reach decades under normal use.
