Apr 11, 2017· This test takes place on new boilers or after any major pressure vessel work. To begin the test, a hydro pump is used to help fill the boiler with water. The water is pumped into the vessel to the maximum allowable working pressure (M.A.W.P.) and brought to 1.5 x the M.A.W.P. It is recommended to not use cold water to hydro test a boiler.

These components are calculated for safety precautions according to the discharge pressure of the dosing pump. These hydro test pumps can obtain delivery pressures up to 400Kg/sq.cm and flow rates up to 10000lts/hr. Our hydro test pumps are extensively used for hydro testing purposes of cylinders, pipes and boiler tubes.

Hydrotest pressure settings vary depends on countrys local code. What you say about 1.5 x MAWP is the minimum setting for hydrotest in new boilers. Here in our country, for mechanical inspection or statutory inspection (renewal of permit)of boiler, we use 1.2 x MAWP, for new and altered boilers,we use 1.5 x mawp. Please review your local code.

AN ACCIDENT WITH BRITTLE FRACTURE DURING HYDROTEST

3. Pressure gauges are to be mounted only after seeing the free issue of water. At times dirt can enter in to the pressure gauge and indicated pressure can go wrong. This is a possibility for over-pressurization. We had come across a package boiler yielding under over pressurization during a shop hydrotest about 20 years back, on this cause. 4.
