What is a crude oil storage tank

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.

Crude oil storage tanks design

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.

Crude oil storage tanks Types

In general, crude oil storage tank has two kinds, fixed roof tank and floating roof tank. Fixed roof tank is   usually used when the quantity of crude oil is not too much. While, floating roof tank is the optimum selection for storing larger quantities of crude oil.

Crude oil storage tanks  standards

In the construction of crude oil storage tank, the most common standard in the world is API650, other standards have GB50341, BS2654, JIS B8501, etc.
