I need help determining whether the channel steel inside the platforms of pumps, unit oil stations, etc. should be completely filled with grout No photos were taken; those who work with this equipment should know what it means. On what standards was it mentioned? Or if any design documents or random materials mention it, one should follow those; no guessing needed. Thank you.
You can check API610; there are regulations regarding this
The poster is raising a question; according to those who have experience in overseeing overseas projects, epoxy resin can be used to fill it.
The chassis is delivered by the manufacturer empty, mainly for ease of transportation. However, all of them are equipped with grouting holes. For grouting to be effective, the chassis must be level and in stable contact with the foundation; the grouting should be even and thorough, with no areas that remain unsupported. It prevents the formation of internal voids, which could cause misalignment of the unit due to vibrations and other factors during operation.
I consulted Sulzer experts, as our pumps are quite large – the volume of the foundation base is 2.3 cubic meters – and there are 18 such pumps in total. The experts from Sulzer replied that, in principle, there is no need for filling, but during operation, if the vibration levels exceed the limits, it is necessary to fill it with shrinkage-free cement. For this very reason, during factory testing, pumps are generally required not to have their pedestals grouted. During the implementation process, they are generally filled to capacity.
I made my deductions based on the information regarding Shenyu’s gas stations.
Faced with the same problem, should grouting be done? There are no requirements in the specifications regarding what kind of grouting is needed
It needs to be filled to ensure a better connection between the steel structure foundations; this is achieved not only through anchor bolts but also to reduce equipment vibration
To prevent water accumulation, most of us use filling (with ventilation holes required)
It’s better to fill it up completely, to prevent the accumulation of dirty oil; it looks better as well and there is less vibration
