Question

Accepted Answer

There are various types of pipes used in construction sites, each with its permissible standby pressure.

Copper pipes: used for water supply and have a permissible standby pressure of 100 psi
PVC pipes: used for drainage and have a permissible standby pressure of 25 psi
Galvanized steel pipes: used for gas supply and have a permissible standby pressure of 500 psi
PEX pipes: used for both water supply and heating systems, with permissible standby pressure varying based on the specific type and application
HDPE pipes: used for underground water supply and have a permissible standby pressure of 100 psi

Accepted Answer

1)PPMD - pressure test is not applicable as we use gravity type of test to ensure there are no leakages
2)CPVC - Pressure test is conducted at a pressure of 8kg\cm² for 24hours to test for any leakages
3)UPVC - These are used for irrigation system with a pressure of 8kg\cm² 
4)SS - Pressure test is conducted at a pressure of 12kg\cm² for 24hours
5)DWC HDPE - These are used for external water and drainage systems and these are tested either using the high pressure water test or smoke test to ensure there are no leakages.
