The Code Book that Rules API 1104: A Comprehensive Guide

When it comes to constructing large-scale storage facilities for oil and other hazardous materials, precision and adherence to strict guidelines are paramount. One such code book is API 1104, which governs the construction of welded steel tanks. In this article, we'll delve into the world of API 1104, exploring its key provisions and why they're crucial in ensuring the integrity of these critical structures.

At its core, API 1104 is a set of guidelines that dictate the materials used for constructing welded steel tanks. According to the code book, plates thicker than 40 mm (1.5 inches) must be normalized or quenched tempered, killed, made to fine-grain practice, and impact tested. This rigorous process ensures that these critical components meet the highest standards of quality.

In addition to material specifications, API 1104 also outlines requirements for plate thickness, with shell plates limited to a maximum thickness of 45 mm (1.75 inches) unless otherwise stated in the code book. Copper-bearing steel is permitted if specified by the purchaser, and steels produced through the thermo-mechanical control process (TMCP) may be used provided they meet specific chemical composition and mechanical property requirements.

The manufacturing process for these plates is also governed by API 1104, with all plates required to be manufactured using the open-hearth, electric-furnace, or basic oxygen process. This ensures a high level of consistency and quality control throughout the production process.

In addition to material specifications, API 1104 also covers the construction of tanks themselves. According to the code book, tanks are composed of three main parts: the bottom, shell, and roof. Each of these components plays a critical role in ensuring the integrity of the tank, and their design and construction must be carefully considered.

Piping connected to the tank is another crucial aspect of API 1104. The code book outlines specific requirements for piping materials, size, and installation, all designed to ensure safe and efficient operation of the tank.

In conclusion, API 1104 is a comprehensive code book that governs the construction of welded steel tanks. By adhering to its strict guidelines, manufacturers can ensure the integrity and safety of these critical structures, protecting people, the environment, and assets from harm. Whether you're an industry professional or simply interested in learning more about the world of tank construction, API 1104 is a valuable resource that's essential reading.

In related news, API 650 (American Petroleum Institute) Welded Steel Tanks for Oil Storage is another code book that plays a critical role in ensuring the safety and efficiency of oil storage facilities. While distinct from API 1104, API 650 shares many similarities with its counterpart, outlining specific requirements for the design and construction of welded steel tanks.

In terms of programming, sorting integer arrays based on their number of occurrences can be achieved using various algorithms. In Ruby, one approach is to define a function that iterates through the array, counting the frequency of each element and then sorts the resulting hash by value. Here's an example of how this could be implemented in Ruby:

```ruby

def sort_it(actual)

actual.inject(Hash.new(0)) { |h, x| h'x' += 1; h }.sort_by { |k, v| v }.reverse.to_h

end

```

This code defines a function called `sort_it` that takes an integer array as input. It then iterates through the array using the `inject` method, counting the frequency of each element and storing this information in a hash. Finally, it sorts the hash by value (i.e., the frequency of each element) and returns the resulting hash.

While this is just one approach to sorting integer arrays, there are many other algorithms and programming languages that can be used to achieve similar results.
