Abstract
A method and a device for absorbing movement in pipe lines comprising an expansion loop system wherein the expansion loop system will absorb axial movement of the pipe without imparting thrust loads to the pipe. The system includes an anchor, a pipe guide for guiding the pipe along a longitudinal axis and an expansion loop member attached along the length of the pipe at severed central open ends of the pipe. The expansion loop member comprises a pair of 90.degree. elbow connectors, a 180.degree. bend return member, and a pair of flexible tube members connecting the elbows to the return member. The flexible tube members accommodate the axial movement of the pipe.
