Is it necessary to use sliding supports for the installation of heat exchangers?
Thread Content
Is the use of sliding supports mandatory for heat exchanger installation, and are there any mandatory regulatory requirements?

Bedroom containers, which include heat exchangers, generally consist of a fixed part and a sliding part; they allow for free expansion and contraction due to thermal expansion.
Is this experience or a standard requirement? I want to know now which standards are mandatory. JB/T4712.1 is the specific approach.
The standards also have requirements; please review the standards in detail.
In horizontal heat exchangers, if the saddle is welded to the shell, a sliding saddle must be installed to prevent excessive local stress in the shell at the saddle area due to temperature differences and assembly stresses. The fixed-end saddle is installed on the side with more pipe openings, or on the side of the inlet pipe, or on the side with the larger pipe openings
In heat medium exchangers, if the saddle is welded to the shell, a sliding saddle must be installed to prevent excessive local stress in the shell at the saddle area due to temperature differences and assembly stresses. The fixed-end saddle is located on one side of the tube box
Vertical heat exchangers do not require them, while horizontal heat exchangers must have sliding supports
