The boiler hydrostatic test is a test of strength and tightness with pressurized water after the boiler or components are assembled. The main purpose of the hydrostatic test is to test the tightness and compression strength of boiler pressure-bearing components, tell whether there is leakage of welding seams, flange joints and pipe expansions, and watch the deformation conditions of pressure-bearing components with naked eyes. Practice has proved that the boiler defects can be found through the hydrostatic test, and the safety of boiler operation can be ensured after the corresponding measures are taken in time. Therefore, the hydrostatic test is an important step and means to ensure the safe boiler operation, direct fired oil heaters.
