GB50366-2005 Technical Code for Geothermal Screw Heat Pump System Engineering
GB/T13663-2000 Polyethylene (PE) Tubular Products for Water Supply
Application Scope
It is applied in the central air conditioning system, floor heating and hot water supply etc. in office building, villa, school, hotel and hospital etc., especially central air conditioning for most common.
Product Characteristics
1. High strength, good property for strain breaking resistance and creep resistance;
2. Excellent toughness and flexibility, adapt capability for uneven foundation and displacement can withstand adverse circumstances such as earthquake and typhoon etc;
3. Excellent weathering resistance including ultraviolet resistance and long-term thermal stability;
4. Corrosion resistance allows no anti-corrosion and long service;
5. Smooth inside wall, small resistance for water flow, large capability for flow and low cost for construction;
6. Excellent wear resistance;
7. Good property for low temperature impact resistance allows safety application in -20∽40℃ and construction in winter not affected;
8. Convenient and reasonable electro-thermal welding or thermal connection, simple construction and maintenance;
9. Overall suitable for the traditional dig construction mode and totally-new non-dig techniques such as push pipe, directional drilling, lining pipe, breaking pipe and submerging underwater etc;
10. Polyethylene material only contains two components of C and H, which is not harmful for human body;
11. Advanced nanometer anti-bacterium technique can effectively inhibit the growth of algae, bacterium and fungus in order to ensure green, healthy and environmental protective transporting pipe for drinking water.
