Regarding the conditions, the issue of equipment load
Thread Content
For storage tanks, the equipment’s empty weight, weight with water filled, and operating weight are generally considered. My question is: is it really necessary to go through such trouble? Why not just specify the maximum weight? Is it meaningful to divide it this way? For equipment that is not storage tanks, such as certain adsorption columns and towers, may I just mention the maximum operating weight?
I don’t think so; are you from a design institute?
There are three different weights: the empty weight of the device, its weight when filled with water, and its operating weight. The weight when filled with water includes both the empty weight of the device and the weight of the water inside it, while the operating weight refers only to the weight of the pipes and valves attached to the device. Therefore, the three requirements are either equipment water filling weight + operation weight + insulation/cooling weight (the equipment requires insulation or cooling)
Should the empty weight of the equipment, its weight when filled with water, and its operating weight all be taken into account in structural calculations? What are the corresponding calculation results or purposes for each of them? Please provide a detailed explanation.
For large equipment, these weight variations can cause settlement of the foundation, and it is necessary to know them separately. What is the maximum allowable settlement?
These parameters relate to issues such as operation, transportation, pressure testing, etc., and need to be provided
There are issues with transportation and lifting
