1. How much pressure can the ppr tube bear? According to national regulations, PPR pipes can withstand a maximum pressure of 16MPa (megapascals). (1 MPa = 10 kg/cm²).
2. It depends on the wall thickness.
Look at this: s is wall thickness (mm), followed by pressure (mpa).
s5=1.25mpa
s4=1.6mpa
s3.2=2.0mpa
s2.5=2.5mpa
s2=3.2mpa
1mpa=10^6 X 1 /(9.8X10^4)kg/cm
= 10.2040816 kg/cm².
