Generally, it is between 1.5 MPa and 2.5 MPa, and must not exceed 4 MPa, and the test pressure standard should be below 0.8 MPa. The value of the heating pressure standard is not fixed, and generally depends on the heating radius, the height of the house floor, etc.
Under normal circumstances, if the heating system is to operate normally, its working pressure should generally be maintained between 1.5 MPa and 2.5 MPa, but cannot exceed 4 MPa. If the pressure test is performed on the heating pipeline, the pressure test pressure should be below 0.8 MPa, and there is no leakage within half an hour to indicate that the pressure test test is qualified.
