Thermal expansion in pipelines,ducts,and vessels which carry hot or cold fluids,or which are exposed to large variation
in ambient temperature, is a major problem conforing designers. As the metal temperature of the pipe, duct, or vessel increases and decreases,its length also varies due to thermal expansion or contraction .Therefore, unless compensation is provided for these dimensional changes, high stresses will be induced in the piping, ducting, or vessel and large forces will be transmitted through the system to anchors and connected equipment.And your system must run at maximum efficiency.
The specially designed metal expansion joint can absorb the different movement as follows:
