Secondary expansion joints are also used in other applications such as, for example, oil field pipelines.
An expansion joint is a form of joint that is located between two structures that are connected or jointed together. The expansion joint contains a mechanical expansion device that permits relative movement between the two structures to be accommodated. For example, in a water main, the water main is formed of metal pipe and the joints are formed of rubber. The expansion joint permits the joint to undergo one or more displacements, thereby to permit the two parts to expand or contract under the effect of changes in temperature.
Conventional secondary expansion joints generally comprise a composite gasket that is positioned in a bore formed in a rigid member, such as a concrete slab, and is adhered to the rigid member by a polymer-based adhesive. The expansion joint is attached to the rigid member by anchors that are threaded into holes in the rigid member. The expansion joint is secured in the bore by an expansion joint washer. The polymer-based adhesive and expansion joint wereher are generally coated with sealant that adheres to both the rigid member and the expansion joint washer, and seals the bore.
In existing water mains and other pipelines, the water main may have been installed for a long period of time. As a result, the water main may be corroded, particularly at the joints and other portions of the water main, thereby creating ingress pathways for the corrosive agents into the water main. Once the water main has been installed for a long period of time, the water main, particularly at the joints, may contain various salts, such as sodium chloride. As a result, the water mains are difficult to maintain, requiring the water mains to be drained and flushed periodically to remove any salt contamination. However, in many water mains, the drain and flush operations are not performed frequently enough. In addition, the drain and flush operations may require that the water main be shut down for the duration of the operation, thereby creating a significant loss of service to the public. In addition, the water mains may contain compounds that may be harmful to the ac619d1d87
