Spring hanger is mainly used for power plant steam pipe or boiler equipment, in the operation of the thermal displacement and equipment installed on the basis of the pipeline force calculation to determine the spring hanger work and thermal displacement requirements, the factory will spring support The frame is set in accordance with the design load: spring preload and set the cold load position; the same time marked with cold theoretical theoretical work position.
 
The spring hanger is set up at the factory factory, and the indicator plate of the spring hanger is fixed at the position corresponding to the installation load by the installation load provided by the manufacturer according to the installation load provided by the user. Spring pipe hanger temporarily in a rigid state. Pipeline after cleaning, water pressure test, remove the upper and lower positioning block, before the pipeline can be put into use.When the pipeline began to run, first check the positioning block is closed, and then check the instructions Whether the displacement of the spring support hanger during the working load is consistent with the design after the pipeline is put into normal operation after the pipeline is put into the work load.When the pipe is stopped, check whether the indicator plate is reset to Install the load position. When installed on the pipe and equipment, for the thread adjustment, the pin off, then the actual load of the spring is required by the design of the cold load
