A good pipeline, should not only have a good economy, and should have a stable and reliable interfaces, material, impact resistance, resistance to cracking, anti-aging, corrosion resistance and a series of advantages insulation Casing, compared with the traditional pipe insulation pvc , HDPE piping system has the following series of advantages: ⑴ reliable connection: the electrical connection between the hot-melt polyethylene pipe systems, the joint strength is higher than pipe body strength. ⑵ low temperature impact resistance: Low temperature brittleness of polyethylene low insulating sleeve pvc, can be safely used within a temperature range of -60-60 ℃. Pfa insulating sleeve, because the material impact resistance, and will not occur tube embrittlement winter construction. ⑶ good stress cracking resistance: HDPE has a low notch sensitivity, high shear strength and excellent anti-scratch ability, resistance to environmental stress cracking performance is also very prominent. ⑷ good chemical resistance: HDPE pipe can withstand a variety of chemical media corrosion, chemicals present in the soil will not cause any degradation of the pipeline. Polyethylene is an electrical insulator, it will not rot, rust or electrochemical corrosion phenomenon; in addition it will not promote algae, bacteria or fungal growth. Applications: ■ widely used in the cable wire connectors, insulation, electrolytic tank, washing machines, television sets, electrical instrumentation coil, battery encapsulation electron source elements can also be used on metal pipes, stationery, work, toys and all other decorative packaging, with moisture, corrosion and other effects. Specifications and color: can be produced with a flame retardant, low creep performance and good electrical properties at room temperature according to customer demand characteristics. (Its biggest drawback is the low softening point and easy to degrade at high temperatures.)
