Construction and calculation of the use of spring support hanger

When the spring hanger is used for construction and calculation, the first thing to do is to do a good check. Check the pipeline design data, the pipeline in the design state and under the completion state of the axonometric layout. The position, number and type of the supporting hanger are checked in the design data and the construction drawings of the supporting hangers are checked to check the consistency of the two. Check and record the design parameters of the pipeline, the actual operation parameters of the pipeline and the successive inspection and change records of the support and hangers. If the pipeline is reformed, it is necessary to review the design and construction records of the pipeline reconstruction. Collate the information that has been consulted, and give all the list of the hangers and the hot and cold inspection items to be checked.
At the same time in order to carry out the pipe stress calculation, to sort out the following basic parameters: the performance of the pipe material, including elastic modulus, allowable stress and linear expansion coefficient; operating conditions, such as temperature, pressure and operation range; various geometric size of the pipe diameter, pipe bending shape and size, type three the insulation condition of the pipeline. Before and after the outage of the unit, the hot and cold field inspection of pipelines and supports and hangers is carried out separately, and the problems of each hanger are recorded. A complete set of pipeline and support hanger running status reports is obtained by photographing the major defects.
When the spring hanger is used for construction and calculation, it is necessary to take a good look at the inspection, and do not make some unnecessary mistakes. The main inspection contents check whether the support hanger has any signs of damage or deterioration, such as the deformation and corrosion of the outer surface of the component. Whether the pipe has been subjected to a large amount of impact load or severe vibration, such as the deformation of the element, the cracking of the welded joint, the loosening of the fixed bolt, or the fracture of the cement. Whether the thermal expansion of the pipe is limited by the building or structural parts. Whether the heat insulation of the pipe is good and whether there is a local bare operation.
