 Installation of Variable Spring


                                                   Designed to support a specified load:

                                                    K weight of the pipe, commodity,
                                                      flanges, valves, refractory &

                                                      operating thermal deflection cycle

                                                   Coiled springs are used to support
                                                   the load and allow movement

                                                   Resistance of the coil to a load
                                                   changes during compression, which
                                                   is why these devices are called
                                                   “variables”

                                                   Many different designs for variable
                                                   supports and a particular
                                                   nomenclature used to identify them
