PPR трубы

Features: 1) Material:RandomPolypropylene. 2) Sizes:16 to 160mm. 3) Pressure Rating:1.25MPa,1.6MPa,2.0MPa,2.5MPa. 4) Colors:Light grey,white ,green or othercolour. 5) Connection:socket fusion joint,electro fusion joint or tran sition joint. 6) Applications:cold or hot water supply,heating system including flooring heating,wall heating and radiating system,central air conditioning system,industrial liquids transportation. Advantages: 1) High temperature resistance:the maximum sustained working temperature is up to 70C,the maximum transient temperature is up to 95C 2) Heat preservation:low thermal conductivity which is only 1/1500 of brass pipe,and 1/250 of steel pipe. 3) Non-toxic:no heavy metal additives,would not be covered with dirt or contaminated by bacterium. 4) Corrosion resistant:resist chemical matters or electron chemical corrosion. 5) Lower installation costs. 6) Higher flow capacity:smooth interior wall result in lower pressure loss and higher volume than metal pipes. 7) Long life:more than 50 years under normal conditions 8) Recycled and environment-friendly.
