Overview of Polyethylene Pipe for Farmland Irrigation:
Polyethylene (PE) pipes are widely used in various manufacturing fields such as sewage, water supply, drainage, and water transportation due to their high strength, high temperature resistance, corrosion resistance, non-toxicity, and wear resistance. The PE chemical name is polyethylene, and the polyethylene pipes used for farmland sprinkler irrigation include low-density polyethylene pipes, medium-density polyethylene pipes, and high-density polyethylene pipes. Because of their wear resistance, acid and corrosion resistance, high temperature resistance, and high pressure resistance, these PE pipes gradually replaced traditional pipe materials such as steel pipes and cement pipes in the market. Especially because this pipe material is lightweight, easy to install and move, it is the preferred choice for new materials.
Product features of farmland sprinkler irrigation polyethylene water supply pipes:
1. Good hygiene performance: The processing of farmland sprinkler irrigation polyethylene water supply pipes does not add heavy metal salt stabilizers, the material is non-toxic, has no scaling layer, does not breed bacteria, and effectively solves the secondary pollution of urban drinking water.
2. Excellent corrosion resistance: Except for a few strong oxidants, it can resist the erosion of various chemical media; there is no electrochemical corrosion.
3. Long service life: Under the rated temperature and pressure conditions, the farmland sprinkler irrigation polyethylene water supply pipes can be safely used for more than 50 years.
4. Good impact resistance: The farmland sprinkler irrigation polyethylene water supply pipes have good toughness and high impact strength, and heavy objects directly pressing on the pipes will not cause the pipes to rupture.
5. Reliable connection performance: The heat fusion or electric fusion interfaces of the farmland sprinkler irrigation polyethylene water supply pipes have higher strength than the pipe body, and the joints will not break due to soil movement or live loads.
6. Good construction performance: The pipes are lightweight, the welding process is simple, the construction is convenient, and the overall project cost is low.
General regulations for farmland irrigation polyethylene water supply pipes:
① Polyethylene PE pipes and pipe fittings should have the product quality inspection report issued by the quality inspection department and the factory's certificate of conformity.
② During storage, handling, and transportation of polyethylene PE pipes and pipe fittings, they should be bound with non-metallic ropes, and the pipe ends should be sealed.
③ During storage, handling, and transportation of polyethylene PE pipes and pipe fittings, they should not be thrown or violently impacted.
④ During storage, handling, and transportation of polyethylene PE pipes and pipe fittings, they should not be exposed to sunlight or rain; they should not come into contact with oil, acids, salts, and other chemical substances.
⑤ The storage period of polyethylene PE pipes and pipe fittings from production to use should not exceed one year.
Inspection of farmland irrigation polyethylene water supply pipes:
① When receiving polyethylene PE pipes and pipe fittings, they must be inspected. First, check the product user manual, product certificate of conformity, quality guarantee certificate, and various performance inspection acceptance reports and other relevant materials.
② When inspecting polyethylene PE pipes and pipe fittings, sample them from the same batch and conduct size and appearance performance inspections according to the current national standard "Water Supply (PE) Polyethylene Materials". If necessary, comprehensive tests should be carried out.
Connection of farmland irrigation polyethylene water supply pipes:
1. Electric fusion welding: Use a dedicated electric fusion welding machine to connect straight pipes with straight pipes and straight pipes with pipe fittings. This is generally used for pipes with a diameter of 160mm or less.
2. Heat fusion对接 connection： Use a dedicated对接 welding machine to connect the pipes， generally used for pipes with a diameter of 160mm or more.
3. Steel-plastic connection： Can be connected by using flanges， threads， and other methods.
