Our company PP-R pipe has S5, S4, S3.2, S2.5 and other four pipe series, usually hot water pipe has S3.2, S2.5 two pipe series.

PPR hot water pipe has good heat resistance. When the working water temperature is 70, it can be used for a long time, short-term use of water temperature to 95, softening temperature to 140, long service life. The service life of PP-R pipes at rated temperature and pressure is longer than 50 years. Good insulation performance. Due to the low thermal conductivity of PP-R, the thermal conductivity of PP-R is 0.21-0.24 W/mk at 20 C, which is much smaller than that of steel pipes (43-52 W/mk and copper pipes (333 W/mk), so PP-R pipes have good thermal insulation
