I have a question: is it necessary to place it on a saddle during the hydrostatic test?

If there is a welding turntable, can the hydrostatic test be carried out on that turntable? Is it necessary to design a special saddle for the hydrostatic test?
If the pressure vessel has a large diameter, having only 4 local supports is not very safe...
Let’s do the calculations; if the weight of the container plus water is within what the tire can handle, then it should be fine. However, it’s absolutely necessary to prevent the rotating shaft from moving; otherwise, it’s hard to say whether an accident will occur~
Has your device been completed? How can a hydraulic test be carried out without completing the work first? If it’s completed in this manner, the test should be done on the ground; welding the turntable for a hydraulic test is not allowed, as this means subjecting the equipment to external forces while it’s under pressure! Not allowed!
This requires analysis on a case-by-case basis; it is necessary to take into account both the load-bearing capacity of the turning tool and its structural design, as well as the number of such tools； At the same time, factors such as the diameter of the container must also be taken into consideration. It is best to calculate the number of supports and their positions during the pressure test of the container. When using wheel supports in general, it is necessary to consider adding thick temporary shims at the support locations to prevent excessive local stress at the point where the wheels come into contact with the container, which could cause deformation of the container.
