Q1: The core difference between PPR pipe and PVC pipe?
Material difference: PPR is thermoplastic plastic, PVC is thermosetting
Temperature resistance comparison: PPR withstand 95 ℃ vs PVC maximum 60 ℃
Connection: PPR hot melt vs PVC adhesive
Q2: How to judge the quality level of PPR pipe?
Look at the light permeability: high-quality pipe is completely impervious to light.
Measure the burning smoke: qualified products burn without black smoke and odour.
Check the certification code: the official website can verify the product test report.
Q3：What are the main use of 32mm PPR Pipe?
Household water supply system: used in household water supply pipe, especially in drinking water system. 32mm PPR pipe is suitable for medium flow of water delivery.
Air-conditioning system: In air-conditioning cooling and heating systems, the pipes are commonly used for condensate discharge, hot water circulation,etc.
HVAC: PPR pipes are also commonly used in the piping construction of floor heating system and central air-conditioning system for conveying hot water or refrigerant.
Industrial piping: It is suitable for some industrial piping systems in low and medium temperatures, such as liquid transport in chemical and food industries.
Agricultural irrigation: due to the stable and corrosion-resistant material of PPR pipe, it is also used in farmland irrigation, horticultural irrigation and other occasions.
Fire-fighting system: sometimes it is also used in the construction of fire-fighting water pipelines, especially in some small and standardised fire-fighting facilities.
Q4: What are the maintenance points of PPR pipes?
Annual pressure test (1.5 times the working pressure)
Regularly check the fixing of pipe clips
Installation of protective casing is required in areas with strong UV rays.
