Shell and Tube Heat Exchanger

Preparation before installing the tube bundle heat exchanger:
The heat exchanger should undergo a hydrostatic test after being installed, with the test pressure set at 1.5 times the working pressure. The steam section should not be less than the steam pressure plus 0.3 MPa; the hot water section should not be less than 0.4 MPa. A pressure drop or leakage within 10 minutes under the test pressure is considered不合格.
The construction and installation unit should precast the concrete foundation according to the base design drawing of the列管换热器(exchanger with tube bundles). Generally, C15 plain concrete is used, and anchoring bolts need to be pre-buried. Before installation, MIO cement mortar should be applied to level the support surface. Equipment installation can proceed only after the foundation strength meets the required standards.
