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

The API 1104 code book, specifically designed for hardcover publications, provides a comprehensive guide for welding and fabrication procedures. This code book is essential for those involved in the construction of welded steel tanks, piping systems, and other related equipment.

One of the primary focuses of this code book is on plate thickness. According to the standards outlined in API 1104, plates thicker than 40 mm (1.5 in.) must be normalized or quench tempered, killed, made to fine-grain practice, and impact tested. Additionally, plates used as inserts or flanges may be thicker than 45 mm (1.75 in.). Shell plates are limited to a maximum thickness of 45 mm (1.75 in.), unless otherwise stated in the code book.

Another important consideration is the selection of materials. Copper-bearing steel must be used if specified by the purchaser, and steels produced through the thermo-mechanical control process (TMCP) may also be utilized provided that certain conditions are met.

API 1104 also outlines specific requirements for manufacturing processes. All plates must be manufactured using an open-hearth, electric-furnace, or basic oxygen process.

In addition to its focus on materials and manufacturing, API 1104 provides guidance on the construction of tanks and piping systems. Tanks are divided into three main parts: the bottom, shell, and roof. Piping connected to these components is also crucial to ensure safe and efficient operation.

For those involved in welding, API 650 (American Petroleum Institute) Welded Steel Tanks for Oil Storage provides a comprehensive guide to welding procedures. This code book outlines specific requirements for welding and fabrication, ensuring that tanks and piping systems are constructed to meet the highest standards of safety and efficiency.

In conclusion, API 1104 is an essential resource for those involved in the construction and maintenance of welded steel tanks, piping systems, and other related equipment. By providing a comprehensive guide to materials, manufacturing processes, and welding procedures, this code book ensures that these critical components are constructed to meet the highest standards of safety and efficiency.
