Abstract
A seal assembly for a pipeline is disclosed. The seal assembly includes a liner with a rubber seal and a gear clamp. The seal assembly is installed by wrapping a liner around a pipeline joint and clamping the liner onto the pipeline utilizing gear clamping. The liner is manufactured using a pure polyurea sheet. A rubberized gasket sealing end is manufactured by spraying polyurea onto a substrate in the dimensions required for a specific size of the pipeline. On installation, the sealing assembly protects the pipeline joints from exfiltration and infiltration.
