Overview of polyethylene water supply pipes for farmland irrigation:
polyethylenePEDue to its high strength, high temperature resistance, corrosion resistance, non toxicity, and wear resistance, pipes are widely used in manufacturing fields such as sewage, water supply, drainage, and water conveyance.PEThe Chinese name for chemistry is polyethylene, which is composed ofPEThe polyethylene water supply pipes for agricultural irrigation made of materials include low-density polyethylene pipes, medium density polyethylene pipes, and high-density polyethylene pipes. becausePEPolyethylene pipes have the characteristics of wear resistance, acid resistance, corrosion resistance, high temperature resistance, and high pressure resistance. They have gradually replaced traditional pipes such as steel pipes and cement pipes in the market, especially because these pipes are lightweight, easy to install and move, and are the first choice for new materials.
Characteristics of polyethylene water supply pipes for agricultural sprinkler irrigation:
1. Good hygiene performance: During the processing of polyethylene water supply pipes for agricultural sprinkler irrigation, no heavy metal salt stabilizers are added. The material is non-toxic, has no scaling layer, and does not breed bacteria, effectively solving the secondary pollution of urban drinking water.
2. Excellent corrosion resistance: except for a few strong oxidants, it can withstand corrosion from various chemical media; No electrochemical corrosion.
3. Long service life: Under rated temperature and pressure conditions, polyethylene water supply pipes for agricultural sprinkler irrigation can be safely used50Years or more.
4. Good impact resistance: Polyethylene water supply pipes for agricultural sprinkler irrigation have good toughness and high impact strength. Heavy objects can be directly pressed over the pipes without causing them to rupture.
5. Reliable connection performance: The strength of the hot-melt or electric melt interface of the polyethylene water supply pipe for agricultural irrigation is higher than that of the pipe body, and the joint will not break due to soil movement or live load.
6. Good construction performance: The pipeline is lightweight, the welding process is simple, the construction is convenient, and the overall project cost is low.
General regulations for polyethylene water supply pipes for farmland irrigation:
①polyethylenePEPipes and fittings should have a product quality inspection report from the quality inspection department and a certificate of conformity from the production plant.
②polyethylenePEWhen storing, handling, and transporting pipes, non-metallic ropes should be used to tie them up, and the ends of the pipes should be sealed.
③polyethylenePEDuring the storage, handling, and transportation of pipes and fittings, they must not be thrown, dropped, or subjected to severe cracking or impact.
④polyethylenePEDuring the storage, handling, and transportation of pipes and fittings, they must not be exposed to direct sunlight or rain;Do not come into contact with other chemical substances such as oil, acid, salt, etc.
⑤polyethylenePEThe storage period of pipes and fittings from production to use should not exceed one year.
Acceptance of polyethylene water supply pipes for farmland irrigation:
①receivePEPolyethylene pipes and fittings must undergo acceptance inspection. Firstly, inspect the product manual, product certificate of conformity, quality assurance certificate, and various performance inspection and acceptance reports and other relevant materials.
②check and acceptPEWhen using polyethylene pipes and fittings, samples should be taken from the same batch and in accordance with the current national standard for water supply(PE)Polyethylene materials should be inspected for specifications, dimensions, and appearance performance, and comprehensive testing should be conducted if necessary.
Connection of polyethylene water supply pipeline for farmland irrigation:
1Electric fusion welding: Use a dedicated electric fusion welding machine to connect straight pipes and fittings. Generally used for160mmThe following pipes.
2Hot melt docking connection: using a dedicated docking welding machine to connect pipes, generally used for160mmThe above management.
3Steel plastic connection: flange, threaded thread and other methods can be used for connection.
