Hydro power test of DI pipes is a method to check the strength and integrity of ductile iron pipes under pressure.

• Hydro power test involves filling the DI pipes with water and pressurizing them to a specified level.

• The test is conducted to ensure that the pipes can withstand the pressure they will be subjected to in actual use.

• Leaks or deformations during the test indicate weaknesses in the pipes.

• The test helps in iden...read more

The hydrotest pressure is 1.5 times the design pressure.

• Hydrotest pressure is the pressure applied to a vessel or pipeline to check for leaks or defects.

• It is usually done before commissioning the system.

• For example, if the design pressure is 100 psi, the hydrotest pressure would be 150 psi.
