Product feature:
1) Good hygienic performance
Rulei Type Three PP-R waster supply pipes and fittings are hygienic and toxin-free, Raw & auxiliary materials are safe and meet with hygienic quality of the products is guaranteed. The inspection and test done by Hygiene and Epidemic Prevention Authority shows that the products meet with national food hygienic standards. The products are green construction materials and can be used in drinkable water piping systems.
Well shaped and light.
2) Easy installation and reliable
Connection is done through thermal fusing, one adapter can be connected to metal pipes and water facilities within a few seconds. High quality stainless steel or nickel plated copper embedded pieces are used safely and reliably.
3) Light to transportation and installation
The weight is 1/8 of metallic pipes. They are convenient in transportation and installation.
4) Good insulation performance and energy saving.
The products have good insulation performance and is energy saving. The thermal conductivity is 1/20 of metallic pipes and the pipes have extremely good insulation and energy saving effect when used as hot water pipes.
5) Well shaped and steady capability
The products possess smooth internal and external walls, small fluidity resistance, mild color and good a shape.
6) Good environmental protection:
The waster products can reclaim, dose not pollute the environment
7) Pressure resistance, Good corrosion resistance, Long lifetime
Max.nominal pressure: 3.2Mpa. Except for few oxidants, the products can withstand the corrosion from many chemicals nor be rusted or corroded. They will not breed bacteria growth or are corroded electrochemically. The lifetime can reach over 50 years, when the piping systems operate under 70¡æ and working pressure of 1.0Mpa. The lifetime under low temperature can reach 100 years.
