For example, other industry standards, reliable engineering tests and analyses, or established industry. By Authority of the Code of Federal Regulations: 49 CFR 195. The absence of guidance or requirements is not to be considered prohibitive to a particular activity or approach that is based upon sound engineering judgment. While this standard is comprehensive, it may not address all issues that may arise. It covers the procedures for radiographic, magnetic particle, liquid penetrant, and ultrasonic testing, as well as the acceptance standards to be applied to production welds tested to destruction or inspected by radiographic, magnetic particle, liquid penetrant, ultrasonic, and visual testing methods. This standard also presents inspection methods to ensure the proper analysis of welding quality through the use of qualified technicians and approved methods and equipment. Answering them provides a valuable review of the section contents. For each section exercise questions and answers are provided at the end of this document. The welds may be produced by position or roll welding or by a combination of position and roll welding. This API 1104 Study Guide consists of an introduction and 15 sections, each covering a specific code section or appendix. The welding may be done by a shielded metal arc welding, submerged arc welding, gas tungsten arc welding, gas metal arc welding, flux-cored arc welding, plasma arc welding, oxyacetylene welding, or flash butt-welding process or by a combination of these processes using a manual, semiautomatic, mechanized, or automatic welding technique or a combination of these techniques. It applies to both new construction and in-service welding. 20 API STANDARD 1104 Table 1Essential Variables for Qualification of Welding Procedure Specifications Welding Variable Subsectiona Change Requiring Requalification Category I (Standard WPS) Category II (Hardness and/or Toughness) 5.4.2. This standard covers the gas and arc welding of butt, fillet, and socket welds in carbon and low-alloy steel piping used in the compression, pumping, and transmission of crude petroleum, petroleum products, fuel gases, carbon dioxide, nitrogen, and where applicable, covers welding on distribution systems.

The API 1104 is a standard that presents methods for the production of high-quality welds through the use of qualified welders using approved welding procedures, materials, and equipment. This document was uploaded by user and they confirmed that they have the permission to share it. Important to occasionally step back and think about where we want to go with the. The new edition of API Std 1104, provides requirements for gas and arc welding used in the construction and in-service repair of pipes and components for the compression, pumping and pipeline transmission of crude oil, petroleum products, fuel gases, carbon dioxide and nitrogen. Incremental improvements to the standard are developed at annual meeting and throughout the year by various subcommittees and task groups. September 2013 (Twenty-first Edition) plus five years. Wide in scope and filled with years of accumulated industry knowledge, the latest edition of 1104 presents inspection methods to ensure the proper analysis of welding quality through the use of qualified technicians and approved methods and equipment. Twenty-second edition of API 1104 is nominally scheduled for 2018. Welding of Pipelines and Related Facilities presents methods for the production of high-quality welds through the use of qualified welders using approved welding procedures, materials and equipment in a new, clearly understood format.
