The maximum allowable working pressure values for V9 & V11 steam boilers is 15 psi. Hydrostatic pressure tests of assembled sections are as follows: Relief Valve Setting (psi) Hydrostatic Pressure Test (psi) 15 (steam) 45 30 45 45 (Canada) 68 50 75 80 120

1 Power boiler − a boiler in which steam or other vapor is generated at a pres-sure of more than 15 psi (100 kPa) for use external to itself. 2 Electric boiler − a power boiler or a high−temperature water boiler in which the source of heat is electricity. 3 Miniature boiler − a …

Author: wareboilers Boilers in thermal power plants work at high pressures and temperature. Hydrostatic tests are mandatory as per boiler regulations to test the integrity of all the parts and joints in a boiler. Water and hydrostatic pumps are used to carry out the test. This article gives a brief on the hydrostatic test principles. Hydrostatic tests are also done on all types of pressure vessels.

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.
