Travel Stop – A device which temporarily locks the movable parts of a Spring Hanger in a fixed position. When the travel stops are installed, the static load (weight of the pipe) will be supported by the spring’s casing (instead of the spring’s coil) making it a rigid support. This static load is then transferred to the supporting structure enabling the piping system to maintain the desired elevation difference between the pipe and supporting steel during erection and/or Hydrostatic Testing.
