A comparative analysis of related stipulations specified in specifications and standards

which are currently in effect at home and abroad

has been carried out

the effectiveness and safety in hydrostatic test of boilers being synthesized.The feasible value of parameters

such as the test pressure

the pressure to be inspected

the speed of pressure rise and drop

the temperature of tested medium etc.

have been given.The test pressure in hydostatic test of boilers has to be 1.25 times of the outlet pressure from the superheater

and has to be no more than 1.1 times of the inlet pressure of economizer

the speed of pressure rise has to be ≤0.3 MPa/min

in the event of pressure being greater than the working pressure at outlet of the superheater

the speed of pressure rise has to be ≤0.1 MPa/min

the water temperature during test is generally 21~50 ℃.
