Crude Oil Storage Tanks

A crude oil storage tank is a container for storing crude oil or other petroleum products, usually can be found in refineries, oil fields, oil depots, and other industries.

At present, 100,000 m³ crude oil storage tanks are the main container to storage crude oil all over the world. Storage tanks should not be built on the foundation with different hardness, or within the impact range of active geological fault zone. For some crude oil storage tanks with high wax content, the seal gland should be designed with a variety of foundations including rainproof, wax scraping, secondary seal, etc. The bottom of crude oil tank is always deposited with a certain thickness of salt water, when storing heavy, high sulfur content and acid value oil, anti-corrosion requirements higher. For large oil storage tank with huge reserves and severe corrosion, the importance of design and set anti-corrosion system is self-evident.

At present, the development trend of crude oil storage tanks scale is larger and larger. The largest crude oil tank in the world is 250,000 m³, 100,000 m³ crude oil storage tanks have been common and they will be the main size now or in the future.
