Evaluation Method of Piping Thermal Expansion

摘要

The difference between the actual flow temperature to the structure the temperature of the analysis input data, such as according to the temperature difference in the wall thickness is maintained between the temperature of the outside air the fluid temperature and the piping, when the volume in accordance with the characteristic change and the pipe shape of the pipe material by the long-term use expansion uncertainties section that follows to interpret the deformation in such driving conditions constraining generated will interpretational problem, the actual amount of deformation that occurs is that all things in the present invention as long as the is what appears consider structural analyzes it to determine the actual thermal deformation of the samgo basic data were parties. However, where there is actual interference of the pipe of this heat deformation does not heat deformation can be accurately generated where free yeolchaeng window appears, it around that the optimal duration is the same system applied to calculate the coefficient of thermal expansion of the place piping to evaluate in using the method to calculate the thermal expansion amount of the thermal expansion of the free area and the result was presented to the process from the health assessment. It said the condition of the piping at high temperature and low temperature and the steps to install a three-dimensional displacement meter in two places at the desired distance (L) as the pipe in free bulge steps and freedoms expanded portion optimal interval that separates parts of redemption dimensional to displacement meter step to read the amount of deformation (dL) of the dividing the amount of deformation (dL) of the three-dimensional displacement gauge to the distance by entering the linear expansion coefficient (al) coefficient (al) step and the linear expansion to obtain performing thermal deformation structural analysis of the pipe full phase and for the actual amount of deformation and thermal deformation of the structural analysis results shown the pipe being used characterized in that to evaluate and adjust the quality of the pipe comprising the steps of the pipe compared to the analysis the amount of deformation at each point in each point of the pipe It relates to a quality evaluation method.
