Issues related to the force exerted by pipes on devices in CaesarII!
Thread Content
1. The pipeline is connected to the tank opening via flanges; now, how can one determine the magnitude and direction of the force exerted by the pipeline on the tank? How is it verified, and what does it look like? Is it necessary to use simulation equipment? 2. The pipeline stress check has passed, but the displacement is between 30 and 40 mm – could this be due to excessive expansion? 3. Which one is better for flange verification? Peq or NC 3658.3? When selecting an ASME model in Peq, which material corresponds to it in the national standards?
1. To calculate the force acting on the pipe outlet, it is not necessary to simulate the entire device; simulating just the pipe outlet is sufficient. 2. This displacement isn’t very large; otherwise, what’s the point of using such long pipe supports? They are meant for sliding. You can check the standard drawings for pipe racks to see the displacement amount allowed for sliding pipe supports. 3. Is there a specification for materials in the HG flange standards? You can take a look
Which one should be used for nozzle verification: absolute, SRSS, or Unity Check? Based on what? Is the eql file selected based on the devices connected via the pipeline? If the pump is connected using API-610, what about when it is connected to a horizontal tank? Both AS1210 and Vessel are standards for containers. Additionally, when entering the X, Y, Z coordinates, is the Y direction generally used as the reference vector direction? Can pipe outlet verification results be generated as drawings? It is possible to determine, just like with ISO, in which direction and to what extent the pipeline exerts force on the equipment
I just learned how to use CaesarII for calculations; thanks to the two people above!
1. The outlets of the calibration equipment need to be modeled at the fixing points of the equipment; if the equipment is not simulated, the displacement of the outlets must be calculated manually； 2. The displacement is not significant, but it is necessary to consider whether the pipe supports might fall off, or whether there could be conflicts with adjacent pipelines ； If it’s deflection, then it’s quite large; it seems that in the cold state it doesn’t exceed 15mm?
I want to know about this too? Now that you know, please teach me. Thank you.
