How to ensure that the pressure of large tank supports on the support beams is balanced?
Thread Content
During the construction, I encountered a large tank with a diameter of φ6000 and a height of 26m. It needs to be installed on the frame beam. There are 8 supporting seats on the circumference of the middle and upper part of the tank. The supporting surface of the supporting seats is a plane of 800×1200. How to ensure that the difference in the positive pressure of these 8 planes on the frame supporting beam is small during installation and that the pressure is balanced? Please give some advice from an expert. Thank you!
If the levelness and concentricity of the frame support part are measured well, and the support of the equipment matches it as much as possible, the purpose may be achieved. It needs to be controlled during the equipment manufacturing process.
For a large tank with a diameter of φ6000, eight support seats are welded to the shell. It is impossible to ensure absolute parallelism and zero height error on the support surfaces of the support seats. Here we will discuss the construction method of how to make the support plane of the support beam consistent with it.
It is not clear where the tank is in the space, how high it is from the ground, and whether temporary supports can be added during the installation process (8 support seats are not needed), including adjusting pads. If temporary support and adjustment pads can be added, it is recommended that the eight support seats on the tank be welded last (at the same time, the welding position and whether the space is feasible should be considered). First of all, the installation or welding of the support beam must be strictly controlled to ensure the levelness of each support plane as much as possible. When the tank is made, the first cylinder section is set at a certain distance from the welding port as an installation measurement reference line (parallel to the weld). Temporary supports are used during installation and alignment. After alignment, 8 support seats are installed and welded to the tank body. During welding, the opposite sides are welded at the same time to control the welding deformation. Since we don’t know the specific structure, weight and surrounding conditions of the tank, this method is only for your reference and may not be feasible.
Thank you for your active participation. The tank is located relatively high and must be installed on the frame beam. As for the issue of back welding of the 8 support seats of the tank, it was originally considered, but was not implemented due to other reasons. This may be a way to solve it. Thank you again!
