PE drainage pipe science small common sense

Release time:

Feb 11,2022

China's plastic pipes are developing rapidly and their quality is constantly improving. Because of its unique advantages, pe drainage pipe is widely used in building water supply, building drainage, buried drainage pipe, building heating, gas pipeline, electrical and telecommunication protection casing, industrial pipeline, agricultural pipeline, etc., mainly used in urban water supply, urban gas supply and farmland irrigation. Polyethylene material is widely used in the field of water supply pipeline manufacturing because of its high strength, corrosion resistance and non-toxic. Because it will not rust, it is the ideal pipe to replace the ordinary iron water supply pipe.

PE drainage pipe has become the second largest plastic pipe type in the world after PVC-U pipe, which is widely used in gas transmission, water supply, sewage discharge, agricultural irrigation, oil field, mining, chemical industry, post and telecommunications and other fields. The application of polyethylene pipe began in the 1940 s. The comonomer content of the first generation polyethylene pipe grade resin is low, such as PE32, PE40 and PE63 grade resin. The extruded polyethylene pipe will become brittle when subjected to long-term hydrostatic strength test. The second generation resin is PE80 grade, and the comonomer content is provided on the basis of the first generation resin, which greatly improves the ESCR resistance of polyethylene pipe grade resin. The third generation resin is PE100 grade. PE100 resin has high density and rigidity. While maintaining good ESCR performance, it improves creep resistance for 20 and 50 years. At present, PE80 and PE100 grade medium and high density polyethylene pipes should be used for gas transmission.pe drain pipeUsually PE80, PE100 grade medium or high density polyethylene pipe, PE63 has gradually become obsolete. PE32 and PE40 polyethylenes are commonly used for irrigation.

Advantages of pe drainage pipe: 1. Long service life: pe drainage pipe can be used safely for more than 50 years under rated temperature and pressure. 2. Good impact resistance: PE pipe has good toughness and high impact strength. Heavy objects are directly pressed through the pipe, which will not cause the pipe to rupture. 3. Reliable connection performance: The strength of the hot melt or electric melt joint of the PE pipe is higher than that of the pipe body, and the joint will not break due to soil movement or live load. 4. Good construction performance: the pipeline is light, the welding process is simple, the construction is convenient, and the comprehensive project cost is low. 5. Good sanitary performance: no heavy metal salt stabilizer is added during PE pipe processing, the material is non-toxic, no scaling layer, and no bacteria, which solves the secondary pollution of urban drinking water. Excellent corrosion resistance: except for a few strong oxidants, it can resist the corrosion of various chemical media; no electrochemical corrosion.

Selection of drainage workspe drain pipeMainly because its construction process is simple, compared with steel pipes, it has a certain degree of flexibility, and more importantly, it does not require anti-corrosion treatment, which will save a lot of processes. But PE drainage pipe also has certain shortcomings: the instrument is not as good as the steel pipe, the construction should pay special attention to the safe distance of thermal heating, do not expose to the sun in the air, to be sensitive to chemical substances, to prevent the leakage of sewage pipes to cause harm.
