Help with equipment installation

For chemical processing equipment, horizontal heat exchangers: are the saddle supports at both ends welded directly to the steel plates provided in the equipment foundation, spot-welded, or placed there without any welding? Another example: how to fix vertical equipment with lugs? Thank you.
Normal spot welding is sufficient. Vertical equipment with lugs must be fully welded, with a section left unwelded at the bottom.
Heat exchanger saddle, fixed at one end and movable at the other
It is generally fixed using foot bolts, with one end being the fixed end and the other end being the movable end (though it is still tightened)
One end of the horizontal heat exchanger is fixed, while the other end is movable; the movable end does not require welding, whereas the fixed end does. Vertical equipment with lugs is generally secured using foot bolts.

This needs to be determined based on the specific circumstances. Pressure, temperature, flow rate, vibration levels, equipment size, and so on affect the installation method of the equipment.
1. One saddle can be welded. Vertical ones can also be welded
How can equipment and infrastructure be welded together? For equipment that has left the factory, unauthorized welding is a serious mistake that must absolutely be avoided. The horizontal heat exchanger is fixed to the foundation using foot bolts, while the other end cannot be fixed and should be allowed to slide. Equipment supported by ear brackets should also be fixed to the support structure using bolts.
Heat exchange equipment usually has one end fixed and the other end sliding; as for how it is fixed, it depends on the design choices
