What issues should be considered when installing a heat exchanger?

First is the acceptance of the foundation and heat exchanger, including its appearance, as well as checking whether the spacing of the embedded foot bolts is within the allowable error range relative to the distance between the bolt holes in the equipment base. It is necessary to check whether the mass of the monolithic concrete foundation is satisfactory, whether the reserved height falls within the allowable error range, whether the exposed height of the anchor bolts is sufficient, and what distance should be left for the locking nuts, as some heat exchanger supports have shims and slides underneath them. Check that the specifications of the shims are complete and that the number of layers does not exceed the limit. It is also necessary to determine the sliding end and the fixed end, as well as to adjust and level the heat exchanger; this can be done using U-tubes or a level. Finally, organize the materials.

Have there been any standards established for learning*?

It is necessary to consider whether there is a core extraction location and whether space has been reserved for piping

SHT 3542-2007 Technical Specifications for the Construction of Installation Projects for Petrochemical Static Equipment – it can be used as a reference

Check whether the owner requires on-site pressure testing; it’s quite troublesome

Check whether the owner requires on-site pressure testing; it’s quite troublesome

Levelness, as well as the slippage of the sliding plate and bolts at the sliding end – 2-3 turns of looseness after fixation

The position must be horizontal; if it cannot be made horizontal, then at least when the device is not in use, there should be no liquid accumulation inside the U-tube. Confirm the locations of the pipes for the cooling medium and the substance being cooled.

What was mentioned on the 4th floor is correct; if core extraction is possible, the location for core extraction needs to be considered.
