The Code Book for API 1104: A Comprehensive Guide to Tank Construction and Welding

When it comes to building tanks, particularly those used for storing oil, it is crucial to adhere to strict guidelines and standards to ensure safety and efficiency. One such standard is the API 1104 code book, which outlines the requirements for tank construction and welding. In this article, we will delve into the details of this code book and explore its significance in the industry.

The API 1104 code book begins by establishing the requirements for materials used in tank construction. Specifically, it states that plates thicker than 40 mm (1.5 in.) must be normalized or quench tempered, killed, made to fine-grain practice, and impact tested. Additionally, shell plates are limited to a maximum thickness of 45 mm (1.75 in.), unless otherwise specified.

The code book also outlines the acceptable manufacturing processes for steel production. It requires that all plates be manufactured using either the open-hearth, electric-furnace, or basic oxygen process. Furthermore, it allows for the use of copper-bearing steel if specified by the purchaser, as well as steels produced through the thermo-mechanical control process (TMCP), provided that the combination of chemical composition and integrated controls is mutually acceptable to the purchaser and manufacturer.

In addition to material requirements, the API 1104 code book also addresses tank construction. It divides tanks into three main parts: the bottom, shell, and roof. The piping connected to these components is also crucial, as it plays a vital role in the overall function of the tank.

API Tank Welding: A Key Aspect of API 650

In addition to the API 1104 code book, another important standard for tank construction is the API 650 standard, which specifically focuses on welded steel tanks for oil storage. This standard provides guidelines for the design and construction of these tanks, including the welding process.

The importance of proper welding in tank construction cannot be overstated. Welding defects can lead to significant risks, such as leaks, corrosion, and even catastrophic failure. The API 650 standard helps ensure that welds are performed correctly by providing detailed specifications for welding procedures, techniques, and testing methods.

In conclusion, the API 1104 code book provides a comprehensive guide to tank construction and welding. Its requirements for materials, manufacturing processes, and tank design help ensure the safety and efficiency of oil storage tanks. By adhering to these standards, tank manufacturers can produce high-quality products that meet the needs of their customers while minimizing the risk of defects or failures.

As technology continues to evolve, it is essential that industry professionals stay up-to-date with the latest developments in code books like API 1104 and API 650. This knowledge will enable them to make informed decisions about tank construction and welding, ultimately leading to better outcomes for their clients and the environment.
