Types of Storage Tanks

 Types of Storage Tanks

Introduction

Storage tanks are used in various industries, especially petrochemicals, to store liquids such as fuel, crude oil, chemicals, and water.
These cabinets are designed to stringent international standards such as API 650 and API 620 to ensure safety and efficiency.

1. Fixed Vertical Storage Cabinets

(Fixed Roof Tanks)
🛢️ Roller tank with fixed roof welded or composite
✅ Ideal for non-flying liquids like water and diesel
The standard : API 650

2. Floating Ceiling Cabinets

(Floating Roof Tanks)
☁️ Floating ceiling on liquid surface to reduce vapour
The types of :

Internal ( Internal )

External ( External )
The standard: API 650, EPA

3. High pressure tanks

(Pressure Vessels)
⚙️ High-pressure cabinets
Used to store gases like propane and ammonia
Standard: ASME Section VIII

4. Ballroom cabinets

(Spherical Tanks)
⚪ Spherical design to distribute pressure evenly
Effective for the questionable gases
Standard: API 2510, ASME


5. Underground cabinets

(Underground Tanks)

Buried to save space or environmental purposes
It is used for fuel, water and chemicals
Challenge: leak detection difficulty.
The standard: EPA UST


6. Fiberglass / Plastic Cabinets

(FRP / HDPE Tanks)
♻️ Corrosion resistant and perfect for chemicals
Made of non metal materials
Features: lightweight - long default lifespan



7. Double wall cabinets

(Double-Walled Tanks)
🛡️ Double-walled tank to isolate leakages
Suitable for hazardous materials
Criterion: NFPA, UL 142

Important notes:

Choose your tank according to: pressure, temperature, nature of matter.

Adherence to standards = Safety + Efficiency.

Always check the recommendations: API - ASME - EPA - NFPA
