Sing-Flex Model "SF" Single Bellows Metallic Expansion Joint Thorburn's single-Flex metallic bellows are specifically designed for piping or ducting applications requiring limited absorption of axial and lateral movements. Where small thermal movements are involved and proper anchoring and guiding is feasible, Thorburn's Single-Flex "SF" series expansion joint system provides the most economical installation. Single-Flex is the base member of Thorburn metal expansion joint family, consisting of a bellows element and end fittings.
Thorburn Single-Flex expansion joint is located near an anchor in a piping run. Each single bellows absorbs the axial movement of the section of piping which it is located. Thorburn Single-Flex expansion joints are also used to absorb small amounts of lateral movement. A directional main anchor must be used to absorb the pressure thrust. |
