The basic equation in US customary units looks something like this: The 1-foot method computes the required plate thickness at a distance of one foot above the bottom of each shell course and is applicable to tanks 200ft (61m) and less in diameter.

5.6.4 Calculation of Thickness by the Variable Point Method.

5.6.3 Calculation of Thickness by the 1-Foot Method.

In this section, there are two methods for consideration: As one would expect, all aspects of the code, both analytical and non-â€¨analytical, are addressed in the meetings.īut getting back to one of the previous questions, how do we decide how thick the wall of the tank should be? The answer can be found in section 5.6, Shell Design. These sessions typically involve lengthy discussions of various agenda items that are important to the refinement and development of the code. These tanks have historically been used to house petroleum for use by chemical plants and power production facilities, as well as basic and strategic reserves.Ī group of dedicated individuals meet on a regular basis to maintain and update the 650 code. This code can be used for designs where the internal pressure is less than or equal to 2.5 psig. At the time of this, the latest edition is the 12th, addendum 2, January 2016. The API 650 code is entitled Welded Steel Tanks for Oil Storage. Using these standards helps to ensure that tanks will be able to stand the rigours of the elements and conditions to which they are subjected.

Tank design codes reflect the culmination of decades of work by many dedicated individuals. They ultimately lie in the pages of the following codes and standards: The answers to these questions are readily available.

What happens to a tank during a hurricane or earthquake?.What internal support structures are needed if the tank has a fixed roof?.Why are some tanks bolted down to the ground and others are not?.How thick do the walls and floors of these structures have to be?.And then in a spark of enlightenment, questions start to pop into the minds of the curious:

The US Energy Information Administration shows crude oil storage capacity utilisation rising steadily.įrom the perspective of the casual observer, these storage tanks just sit there doing their job day in, day out. The design and maintenance of atmospheric and low pressure vessels for oil storage is becoming ever more vital as crude oil storage capacity utilisation rises and oil storage capacity grows globally.
