Description features:Features:1) Innocuity, hygiene: the material of pipe is innocuous, it is belonging to healthy construction material, non corrosion, can't collect dirts, it improves the water quality in the pipe network efficiently2) Anti-corrosion: polyethylene is inert material, besides few strong oxidant, it can withstand corrosion of varieties of chemical medium, therefore, the pipe has the feature of no electric chemistry corrosion, in addition, the corrosion-proof coat is not needed3) Non-leakage: polyethylene pipe mainly adopts the thermal casting connection or electrocasting connection, it has the good capability of withstanding the pressure of water hammer, thermo-weld joint integrated with the pipe and polyethylene pipe has the resistance capability to ground motion and terminal load, it can improve much for the safety and reliability of water supply4) Low flowing resistance: absolute roughness of inner wall of polyethylene pipe is not more than 0.01mm, and the new steel pipe and nodular graphite pipe k≥0.06mm, it is good for reducing the energy consumption of water supply5) Strong toughness: the material of polyethylene water supply pipe has the feature of strong toughness, elongation at break usually exceeds 500%, strong adaptability to the pipe base unbalance subsiding, it is the pipe that has the good shocking resistance property6) Fine flexibility: due to the flexibility, polyethylene pipe can roll, it can be supplied with longer length, it avoids amounts of joints and pipe fittings, it is good for increasing this material economic value to pipe line project7) Superior anti rapid fission property: polyethylene pipe has advantages like fine capability of resisting the rapid crack passing, superior anti- scratching and extruding performance of anti environment stress breaking8) Long service life: the safety service life of polyethylene pressure pipe is more than 50 years9) Liable to recycle: the polyethylene material can be recycled, even if it is burned, it can't bring the material to influence the environment
