Non standard dual unit

Dual Expansion Joints are often used where axial movement is grater than can be absorbed by a single Expansion Joint. The dual assembly consists of two single Expansion Joints connected by an interconnecting pipe nipple. In many cases, this interconnecting nipple has an integral anchor base. The base is designed to withstand the forces required to move either expansion joins. when no anchor base is provided, the interconnecting nipple must be anchored with standard pipe anchors.

Dual Expansion Joints are employed where large amounts of movement in any combination are required. i.e. axial, lateral deflection and angular rotation which can not be absorbed by a single expansion joint. In these types of application, the interconnecting nipple is not anchored by the remaining system must be properly anchored and guided.

Liners and Covers

LINERS AND COVER

Liners and Covers are used to provide additional protection to the thin wall bellows element of the expansion joint. Dents or other damage to the bellows will materially affect the performance of an expansion joint and a cover should be used where conditions warrant this additional protection.

Liners or internal sleeves are used to minimize contact with the medium, smooth flow , control erosion and eliminate resonance where flow velocities are high.

FLEXIBILITY
Unaflex offers various liner designs. Drop in liners are avvailable which allow easy maintenance and replacement. Flared liners welded directly to the expansion joint are designed to allow proper clearance for expansion joint motion.
