| Abstract: | The reliability of various expansion joints used for overhead heat-supply pipeline in subsidence area of coal mine is analyzed. The arrangement mode of rotary expansion joint is introduced. The economic efficiencies of pressure balanced bellows expansion joint, lateral big tie bellows expansion joint, hinged bellows expansion joint, ball expansion joint, square expansion joint and rotary expansion joint suitable for overhead heat-supply pipeline in subsidence area of coal mine are compared. The rotary expansion joint has the best economic efficiency, is ranked second in reliability among six expansion joints, and its comprehensive index in economic efficiency and reliability is the best. |
