Krishi Hot & Cold CPVC pipes are produced in accordance with ASTM D-2846 in in SDR 11 & 13.5.
DR-11 pipes are rated at a continuous working pressure of 400 psi at 23°C and 100 psi at 82°C. SDR-13.5 pipes are rated at a continuous working pressure of 320 psi at 23°C and 80 psi at 82°C. Margin of safety is provided, should unusual short-term conditions be encountered above these levels.
Various tests conducted both by our in-house testing lab and other recognised Test Labs are:
" Krishi Hot & Cold " CPVC Pipe doesn"t breakdown even under harshest of water conditions so there is none of the purity worries from corroded metal Pipe or soldered joints. " Krishi Hot & Cold " CPVC Pipe keeps pure water pure.
- Dimensional Tests: To ensure that all dimensions confirm to appropriate standards.
- Flattening Test: Sample Pipe are compressed to check that despite compression Pipe do not crack.
- Burst Pressure test: Ensures maximum internal pressure to be over three times normal pressure rating for the pipe.
- Heat Reversion Test: Ensures residual stresses left in pipe after the pipe is produced.
Even after years of use in the most aggressive service conditions, " Krishi Hot & Cold " CPVC piping won"t corrode, standing up to low pH water, costal salt air exposure and corrosive soils." Krishi Hot & Cold " stays as solid and reliable as the day it was installed. It maintains full water carrying capacity because of no scale build up which causes water pressure loss.
