    Overview of “Piping Expansion Loop” on the piping PE100

    Multiply the total expansion of each line between its proposed anchors by the pipe’s moment of inertia E. The stiffness of a line is measured by its “Moment of inertia.” The line with the largest of these calculated nuers will require the largest loop, the next smaller nuer, the next smaller loop, etc.
