Storage Tank Standards
The following table is API standards that are relevant to the design, manufacture, installation, inspection, operation of storage tank for petroleum products.
| API Standards | Title | Description |
|---|---|---|
| API-620 | Design and Construction of Large, Welded, Low Pressure Storage Tanks | Guide for construction of storage tanks with inner pressure up to 15 psig. And for large storage tanks which are field erected, or are used for the storage of petroleum intermediates and products. |
| API-650 | Welded Steel Tanks for Oil Storage | To control the construction of tanks which stores hydrocarbon products at a low operating pressure (up to 2.5 psig). |
| API-651 | Cathodic Protection for Above Ground Petroleum Storage Tanks | Discussion on the corrosion in petroleum storage tank and associated pipes. Introduce about two common methods about providing cathodic protection against corrosion. |
| API-652 | Lining of Above Ground Petroleum Storage Tanks | Effectively limit the corrosion through the lining at the bottom of steel storage tank, which is used to store hydrocarbon. Guide for the lining materials, their applications, inspection of tank bottom lining, etc. |
| API-653 | Tank Inspection, Repair, Alteration, and Reconstruction | Guideline for inspection, repair, alteration, and reconstruction of above ground hydrocarbon and chemical storage tanks, which is made of steel. Minimum requirements for maintaining the integrity of welded or riveted, non-refrigerated, atmospheric, above ground storage tanks, are discussed. |
| API-2000 | Venting Atmospheric and Low-Pressure Storage Tanks | Guideline for normal and emergency vapor venting requirements for above ground petroleum product tanks, above ground and underground refrigerated storage tanks. The tank is discussed to be designed for low pressures ranging from full vacuum to 15 psig. |
| API-2015 | Cleaning Petroleum Storage Tanks | Guideline for preparing, emptying, isolating, ventilating, atmospheric testing, cleaning, entering into, hotwork and recommissioning activities in, on and around atmospheric and low-pressure (up to 15 psig) above ground storage tanks containing flammable, combustible or toxic materials. |
| API-2517 | Evaporating Losses from External Floating Roof Tanks | Guide for estimating the total evaporation losses or atmospheric hydrocarbon emissions from external floating roof tanks containing multicomponent hydrocarbon mixtures or single component storage stocks. |
| API-2519 | Evaporating Losses from Internal Floating Roof Tanks | Summary about performances of internal floating covers to prevent evaporation losses. Effects of internal floating covers on tank operation as well as the provisions for gaging, sampling, and temperature reading are described in the document. |
| API-2350 | Overfill Protection for Petroleum Storage Tanks | Covers overfill protection for all aboveground storage tanks in petroleum facilities, including refineries, terminals, bulk plants and pipeline terminals that receive Class I (flammable) or Class II (combustible) liquids. |
| API-2550 | Measurements and Calibration of Petroleum Storage Tanks | Procedures for calibrating upright cylindrical tanks which are larger than a drum or a barrel. Procedures for making measurements are discussed in Part I of the document and methods of calculating the tank volume are given in Part II. |
