Bottom cleanout boxes
Bottom cleanout boxes are used for removal of bottom settlings and other sediments, sedimentary rocks from the vertical tank bottom and shell. They are mounted in the lower part of the shell and provide access inside for scheduled maintenance, which can be carried out only after tank emptying.
Their application is indispensable for the heavy and viscous petroleum products with high density storage.
Bottom cleanout boxes manufacture
The Saratov Reservoir Plant produces the following sizes of cleanout boxes:
Overall dimensions are calculated at the design stage and depend on the tank capacity. Below there is a dimension sheet in accordance with GOST 31385-2016 "Vertical cylindrical steel tanks for oil and petroleum products. General technical specifications", which is guided by our specialists while designing and manufacturing of cleanout boxes.
In terms of design, it is a hole in the first ring, pressure tight closed when petroleum product is inside. In order to avoid a welded joint breakage, a reinforcing plate is attached to the outside of the shell and on the bottom.
The material should be similar to the steel grade of the tank.
We supply bottom cleanout boxes separately and in a complete with vertical tanks as well. The equipment is transported separately from the primary steel members, together with the plate and supporting structures, which are placed inside in the erection procedure.
