        Green safety PE solid-wall pipe

        The raw material is 100% HDPE batch mixed batch,product quality and stability,with good safety performance. We manufacture the metric system and Imperial standard product according to chinese standard and ASTM.

        performance advantage

        Good hygienic properties No added metal salt stabilising agent、 no toxin, no dirt, no bacterium, solves the problem that secondary contamination of urban drinking water well

        Long Using Life under the rated temperature and pressure, PE pipes may be used for over 50 years.

        Reliable connectivity PE pipe hot melt or fused interface strength is higher than the pipe body, joints will not load due to soil movement or the role of living off.

        Good Work ability pipe is light, welding technology is simple, construction is convenient, and it is low for engineering comprehensivecost.

        Excellent corrosion resistance can withstand a variety of chemical erosion except a few strong oxidant

        Excellent impact resistance Good Toughness, high intensity and impact resistance,not pipeline rupture resulted from direct heavy Pressure in the PE pipe above.

        Strong wearability. Quadrupled common steel pipe‘s wearability with the same condition.

        Production technology

        nachuan and the introduction of domestic outside the most well-known equipment manufacturers of pipe extrusion machine fitting injection molding machine welding equipment and other peripheral equipment, as the most important pipe extrusion equipment, pipeline system equipped with the most advanced production control system, to achieve 100% thickness online wall defect scan, ensure the quality of each pipe
