1. Use fixed supports to divide the pipelines appropriately, turning them into safe, reliable, and easily compensable units. 2. During the installation of the line units, it is necessary to ensure the straightness of the pipelines, and the fixing brackets must have sufficient stiffness and strength. In general, the vast majority of failures in straight pipelines are caused by unreliable fixed supports. 3. For L-type, Z-type, and II-type units, it is necessary to appropriately select bellows compensators such as hinge type, large tie rod type, and hinge-type large tie rod type, taking into account the impact of additional displacement. 4. In situations where the load-bearing capacity of fixed supports cannot meet the requirements, such as in indoor pipelines, turbines, condensers, fans, and other applications where the stress on the pipes is limited, a bypass-type pressure-balancing compensator can be used. These include straight-tube with three bellows pressure-balancing types, large-link types, hinge types, and other compensators that do not generate any pressure thrust. 5. For devices that require extremely low stress, precise calculations can be used to make the pressure balance compensator generate an unbalanced pressure thrust in the opposite direction with an adjustable magnitude, so as to counteract the elastic force and frictional force and achieve a fully balanced pipeline system; this represents a new approach.
