Rubber Compensators: Used in heating/cooling pipelines to compensate for thermal expansion/contraction and reduce stress.

Metal Joints: Widely used in water supply, heating, and HVAC systems (e.g., cold/hot water pipes in high-rises).

Metal Bellows: Used in drainage, ventilation, and heating pipelines to adapt to thermal expansion and vibration.

Rubber-Lined Pipes: Rarely used in standard construction but suitable for specialized corrosion-resistant drainage systems.
