What are some essential Types of Tank Inspections?


It is impossible to stress the necessity of tank inspections. Tank spills may wreak havoc on the environment and contribute to field and tank site injuries. Tank spills can also result in aesthetic issues, costly maintenance, or tank failure. Finally, frequent tank examinations are critical for detecting and resolving potentially disastrous tank problems. Failure to get your tank inspected on a regular basis can result in serious repercussions, ranging from personal harm to large fines from the U.S. Environmental Protection Agency.

Now, the question comes, what are the various types of tank inspections. Here is the answer.

Tank Inspection Types

  • Steel Tank Institute Inspections or STI

The Steel Tank Institute (STI) mandates aboveground storage tank examination requirements. The STI SP001 Specification is a procedure that covers shop-erected tanks, field-erected tanks, and transportable vessels. Tanks that are SP001-applicable are those that contain stable, explosive, and flammable liquids at 200 ℉ at atmospheric level. Tank entrance is not required under the STI SP001 Standard for tanks under 30,000 barrels. However, leak-test examinations are frequently used as a substitute.

  • American Petroleum Institute 653 Code for Tank Inspections

The American Petroleum Institute (API 653) inspects field-erected containers, API 650 tanks, and API 12D tanks. API 653 may apply to tanks with a capacity of 30,000 gallons or more for in-service examination, maintenance, modification, and rebuilding.

In compliance with API requirements, most container examination service companies provide the following:

API-certified inspectors completed the inspections.

Corrosion rates, tank life expectancy, tank problems, and repair suggestions are all included in the reporting.

Tank inspections using cutting-edge equipment that provides access to previously inaccessible locations. 

Electromagnetic tank crawling, ultrasonic density gauges for cast steel, heavy steel measurement techniques, and bottom monitoring with MFE testing for bottom side rusting of steel tank floors are among the equipment available.

  • National Fire Protection Association and American Water Works Association

The National Fire Protection Association (NFPA) and the American Water Works Association (AWWA) require certain tanks to be inspected. According to the NFPA website, the organization’s mission is to “reduce death, injury, property destruction, and financial damage owing to flame, lightning, and associated dangers.” The goal of the AWWA is to increase the quality of the water and supply, which is linked to effective storage tank administration. Both authorities must be followed in order to protect the environment and personnel.
