Thrust problem at the pipe outlet of vertical equipment
Thread Content
Dear seniors, I’m thinking of a tower unit we worked on earlier. The piping team mentioned that the thrust exerted by the pipes was quite high. When designing such a tower unit, should the pipe thrust be considered based on local stresses or on overall stress levels? When designing the foundation bolts for tower-type containers, should the impact of pipe thrust on the number of foundation bolts be taken into consideration?
It is best to perform local stress calculations; integrating the pipeline thrust into the overall calculation of the tower certainly has an impact on the foundation.
Local stresses need to be calculated, as do the anchor bolts; meanwhile, the wall thickness of the equipment below the pipe opening also needs to take these forces into account. SW6 already has the horizontal thrust value inputted – just enter it as required.
It does not necessarily affect the number of foot bolts, but when calculating the supports including the foot bolts, it is necessary to take into account the effect of the interface loads on the supports; this depends specifically on the direction of the interface as well as the magnitudes of the forces and moments in various directions
