Discussion on the calculation of the thickness of pre-welded components for Type N pipe racks in the HG/T21629-2021 pipe rack standard drawings
Thread Content
In the standards, the wall thickness of the ear supports is determined by the equipment engineer based on load calculations. What calculation method is used? Please, experts, give me some advice!
In the HG/T21629-2021 standard, the calculation of the wall thickness of the lug is typically carried out using relevant formulas from structural mechanics and material mechanics. The calculation takes into account factors such as the loads borne by the pipe rack, the properties of the bracket materials, and the safety factor. The specific calculation methods may need to be adjusted accordingly based on the actual engineering requirements and design specifications. Typically, equipment engineers use finite element analysis software for simulation analysis to ensure the accuracy and validity of the calculations. .
I don’t see the attached image! Is the local stress calculated based on what was taken over?
I’m currently using a DN8400 unit, with a force of 89KN applied to the bracket; the point where this force is applied is 1500 units away from the wall of the cylinder. Based on calculations related to local stress in the fittings, it turns out that the thickness required is very large, and the gaskets needed are also quite big. I’m not sure if these calculations are correct.
