Rubber Compensators: Rarely used directly but suitable for flexible compensation in pipelines with displacement .

Metal Joints: Critical for connecting pipelines in oil extraction, transporting crude oil, natural gas, and high-pressure fluids.

Metal Bellows: Used to connect pumps, compressors, and storage tanks, absorbing vibration and pressure fluctuations in oil/gas pipelines.

Rubber-Lined Pipes: Applied in crude oil transportation, natural gas gathering, and wastewater reinjection to resist corrosion and abrasion.
