A detailed description of the power tubes PE: ● PE power tubes are traditional steel pipe, PVC pipe drinking ethylene text replacement. ● PE power tubes must withstand a certain pressure, usually opt for large molecular weight, good mechanical properties of PE resins, such as HDPE resins. LDPE resin is low tensile strength, pressure difference, poor rigidity, poor dimensional stability during molding, and the connection difficulties, suitable as water pressure tube material. ● PE pipe power but because of its high health indicators, LDPE LLDPE resins in particular the production of drinking water has become a commonly used material. LDPE, LLDPE resin melt viscosity is small, good fluidity, easy processing, ● PE pipe and thus their power to select a wide range of melt index is also usually MI between 0.3-3g / 10min ● PE pipe a good power The pipeline, should not only have a good economy, and should have a stable and reliable interface material impact resistance, resistance to cracking, anti-aging, corrosion resistance and a series of advantages compared with traditional pipe, HDPE piping system has the following series of advantages: ⑴ ● PE pipe connection and reliable electric power: the electrical connection between the hot-melt polyethylene pipe systems, the joint strength is higher than the pipe body strength. ⑵ ● PE power tube temperature impact resistance: Low temperature brittleness of polyethylene is very low, can be safely used within a temperature range of -60-60 ℃. Construction in winter, due to material impact resistance, and does not occur tube embrittlement. ⑶ ● PE power tube good stress cracking resistance: HDPE has a low notch sensitivity, high shear strength and excellent resistance to scratches capacity, resistance to environmental stress cracking resistance is also very prominent. ⑷ ● PE power tube 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 the electrical insulator, ● PE power tubes it will not rot, rust or electrochemical corrosion; moreover it will not promote algae, bacteria or fungal growth. ⑸ ● PE pipe anti-aging power, long life: polyethylene pipe containing a uniform distribution of 2-2.5% of carbon black can be stored or used for 50 years in the outdoor open air, will not be subjected to ultraviolet radiation damage
