The spring hanger is an important part of the piping system and plays an important role in bearing the pipe load, limiting the displacement of the pipe and controlling the vibration of the pipe. The hanger configuration (load state, type, position) directly affects the stress distribution of the pipe system And the size of its performance is good or bad, whether the bearing is reasonable directly affect the service life of the pipeline and safe operation.As the pipeline support hanger in the design and installation process may exist superconducting automatic explosion-proof door some of the composite insulators, After the operation time, the shape and position of the pipeline and the performance of the components such as the hanger spring may change, such as the damage of the hanger, overload, underload and displacement obstruction, resulting in the increase of the ball screw in the local area of ??the pipeline, The increase in the thrust of the end point (or equipment), etc. The emergence of these problems will inevitably affect the safety and economy of the operation of the equipment.We have not been the main pipe support hood of the state and operation of the system carried out a test, Analysis and adjustment.In order to solve the pipeline hanger in the design, installation and operation of the problems, to eliminate the support due to the hanger Caused by the safe operation of the unit hidden danger, there are more impact on the pipeline life and safe operation of the hidden dangers.We are the main steam group stabilizer acidification inhibitor, reheat steam, high pressure bypass valve and low pressure bypass valve before Pipe to support the hanger to test and analyze, in order to improve the operation of the pipeline and the hanger to achieve the safety of equipment, the purpose of economic operation by the manufacturer according to the user to provide the installation load, use the upper and lower positioning block will spring support Hanger of the hanger plate fixed in the corresponding position with the installation of the load, so that the spring hanger temporarily in a rigid state. Spring support hanger pipe after cleaning, water pressure test, remove the upper and lower positioning block, When the pipeline is in operation, first check whether the spring hanger positioning block is removed and check whether there is any jamming in the process of displacement of the modified asphalt equipment from the installation load to the working load. After normal operation, check whether the displacement of the spring support hanger at work load is consistent with the design.When the pipe stops running, check whether the spring hanger plate is reset to the installation load The position of the pipe or the device when the displacement, as long as the pre-selected load displacement, no matter how much the displacement changes, they can be constant spring through the bracket and always get a constant support force, so the spring hanger will not To the pipeline or equipment to bring new additional pressure, so you can avoid causing significant equipment and safety accidents in the use of the process should be strictly in accordance with the spring hanger standard operation to prevent the occurrence of security incidents.
