ABSTRACT:
A flexible pipe loop for absorbing or compensating for movement in a pipe run, and for reducing stresses in the pipe run. The loop comprises a pair of pipe run elbows, a pair of flexible tube members, a pair of loop elbows, and a third flexible tube member. The pipe run elbows are oppositely disposed, and each has a first open end to be connected to the pipe run, and a second open end. The pair of flexible tube members each have first and second open ends. The first open ends of the tube members are connected to the second open ends of the pipe run elbows, respectively. The loop elbows are disposed in a spaced-apart opposing relation, and each has first and second open ends. The first open ends of the loop elbows are connected to the second open ends of the pair of tube members, respectively. Finally, the third flexible tube member is connected between, and to the second open ends of, the loop elbows.
