Abstract

A pipe restraining system has first and second pipes. Each pipe has an axis and a groove adjacent an axial end thereof. A bushing bridges and hydraulically seals with the first and second pipes. First and second clamp rings are removably attach the bushing to a respective one of the first and second pipes. When the pipe restraining system is assembled, axial tensile loads passing through the first pipe are transmitted through the first clamp ring, the bushing and the second clamp ring to the second pipe. An axial distance between the first and second pipes remains substantially constant.
