1. Highlights of the inspection by the State Quality Inspection Bureau index test, fully meet the national standard. 2. Direct manufacturers, product quality is fully guaranteed. 3. strict production factory, production lines and rigorous. 4. On the tensile properties, corrosion resistance, resistance coefficient, thermal conductivity, bacteria, and other unique properties of life, excel. 5. All products sets, into a series, once used, are all the same quality, the same performance, no individual or tube defects. Advantages 1, good impact resistance layer co-extrusion production process, will not resist leaving layered performance. 2, superior chemical resistance. 3, excellent soft pressure performance. The pipeline external loads, do not break, can resist the impact of stress and reduce water hammer damage, ensure safe operation, the role of negative pressure to maintain Hong 4, HDPE pipe over the case of water ice will be with elastically stretchable, After the ice melted restitution, cryogenic freezing to avoid damage to the pipe 5, environmental performance, non-toxic product, to avoid environmental pollution. 6, HDPE pipe is a flexible material, low elastic modulus, low noise generation, providing a good home, office environment 7, HDPE pipe wall is smooth, good water conditions, traffic, does not produce deposition phenomenon 8, HDPE None toxic tasteless, health and safety and reliable for food production lines and water pipes. After combustion produces carbon dioxide and water, it does not produce harmful gases several standard properties Density: 0.94--0.96g / cm3 melt index: 0.3--0.6 Tensile strength: 50mm / min: 19pa elongation at break: 50mm / min: > 30% modulus of elasticity: 760pa oxidation induction time: (200 ° C):> 30mins longitudinal reversion: (110 ± 2-- ° C, 30min): ≤3% Appearance: uniform color, no bubbles, no obvious scratches, dents, impurities and other defects. Low temperature resistance: pipe with ice expansion, with the ice melt recovery. Flexibility: resistance to traffic, vibrations caused by the low thermal resistance: heat loss 90% less than copper radiation: Can anti slight radiation. Wear: Internal smooth, wear-resistant, maintain high drainage performance. Low noise: HDPE low elastic modulus, good flexibility, dramatically reducing the structural noise. Construction and installation: easy installation, high efficiency service life: 50 years of fighting specifications diameter: 50--160 thickness: 110 Nine, Zhengzhou Huida service Pre-sale services: one on one with customers to recommend products based on the specific circumstances . In this process, our staff will contact the customer in real time and give relevant recommendations; in special circumstances, then our sales can be field trips, interviews with clients. Sale of services: in conversation with customers, our staff depending on the circumstances offer, or as circumstances permit, it can conduct interviews with a sample of customers. And, after the offer to the customer's satisfaction and solve related problems. Service: After the customer payment, we will arrange a special delivery staff and vehicle handover to the customer designated area, such as the product in question, can be returned. During the installation process, we have professional and technical personnel to the scene to guide the installation. Ten, Zhengzhou Huida Plastic Co., Ltd. uphold the leading technology, industry advocacy style; marked superior quality, our brand. China plastic pipe to create one-stop shopping center!
