Storage tanks are containers that are used to hold liquids, compressed gases or other mediums. Storage tanks can be made from various materials but most commonly are fabricated using carbon steel or stainless steel.
TYPES OF STORAGE TANKS:
- They are typically cylindrical in shape and can be designed to be used either above or below ground.
- Pressurized storage tanks are fabricated, certified and stamped per ASME Section VIII, Division I.
- Pressurized storage tanks can be vertical or horizontal.
- No pressure or very low pressure storage tanks can be certified to various API or UL standards and the type of material the tank will store regulates the type of certification that is required.
- The major design codes for welded atmospheric tanks are API 650 and API 620.
- Most storage tanks are shop fabricated but very large storage tanks can be field erected.
Obviously, safety and longevity are important qualities to consider when purchasing a storage tank. The materials used should be of the highest quality and the welds should be inspected and the tanks should be leak checked. When shopping for a storage tank, do your homework and find a fabricator that puts quality first!
