How to choose the right type of industrial tank according to your process needs
Introduction
Selecting the right industrial tank is key to ensuring safety, efficiency, and operational continuity in any production plant. The choice depends on factors such as pressure, temperature, fluid type, required capacity, and applicable regulations. Here's how to make the best decision.
Atmospheric tanks vs. pressure tanks: which one do you need?
Atmospheric tanks (such as API 650) are used when the fluid operates at ambient pressure, while pressure tanks (such as ASME Section VIII and API 620) are designed to handle internal or external pressure.
Choosing the wrong one can result in structural failures or product loss.
Materials suitable for each fluid
The material directly impacts the safety and lifespan of the tank.
Most common options:
- Carbon steel: Ideal for hydrocarbons and fuels.
- Stainless steel: Recommended for corrosive chemicals or foods.
- Special alloys: for high temperature or severe corrosion.
Regulations that influence the selection
Depending on the industry and process, it may be mandatory to comply with:
- API 650 – Atmospheric tanks.
- API 620 – Tanks for moderate pressure.
- ASME VIII Div. 1 – Pressure vessels.
- NFPA / UL – Fuel handling.
Complying with the appropriate standard avoids penalties and ensures operational reliability.
Common mistakes when specifying tanks
- Do not calculate thermal cycles.
- Ignore internal corrosion.
- Incorrect selection of accessories.
- Do not allow space for future maintenance.
