Software
Rilotank 3D is a technical software for the design and calculation of metal tanks (carbon steel or stainless steel), welded (not bolted), vertically oriented (it does not cover horizontal orientation, nor spherical shape), for the storage of fluids (in liquid and/or gaseous state – it does not cover the storage of solids and therefore, neither fluidised solids). The storage of such fluid must meet the following conditions in terms of pressure and temperature:
Pressure: ≤ 18 KPa
Temperature: ≤ 260 ºC
Although a series of considerations must be taken into account with respect to the pressure that will be studied in “Design at internal pressure according to Annex F of API 650” and to the temperature that will be studied in “Requirements of Annex M of API 650 due to high temperatures”. You can watch the video presentation of the software:
The software RiloTank 3D V. 2026 is a software application that performs 3D tank design and calculation according to API 650 14th. It also performs the calculation of wind and seismic loads according to ASCE, the standard on which API 650 14th is based. The software provides several reports in PDF and WORD with all the calculations performed, list of materials and Annex L filled in according to API 650, which can be used as supporting reports of the calculations performed. It also exports the 3D design of the tank with all the details in DWG, DXF and HTML formats for quick visualisation of the tank by the customer, designing the cylinder plates, the roof, the bottom (ring bottom if necessary), the wind rings and the saddles and anchor bolts, see figures:
