Review relevant DOT parts and the API 1104 to see which Sections are referenced and within the 1104 which Sections may be referenced. Not all of API 1104 is Incorporated By Reference. Continuing to use an edition that has been replaced by a more current edition is not typically frowned upon as long as any additional work is in compliance with the current Incorporated edition. Currently as of Januthe 20th edition of API 1104 is still the listed edition therefore it is required that this edition be used for any work that is covered by DOT. DOT CFR Part 192 and 195 has lists of documents that have been Incorporated By Reference (be sure to read the explanation of what Incorporated By Reference means). For example, other industry standards, reliable engineering tests and analyses, or established industry.Yes, you are correct.

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. The welds may be produced by position or roll welding or by a combination of position and roll welding. 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.

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. This standard presents methods for the production of high-quality welds through the use of qualified welders using approved welding procedures, materials, and equipment.

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. 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. Please note: for the non-English versions of this standard, addenda and errata may not be included.ĪPI Standard 1104, 21st Edition is the industry standard for welding practices. The official version of the standard that accompanies the purchase of the redline, will include the updates (addenda, errata). Please note: The redline edition of this publication is a comparison of the original version of the 21st edition to the 20th edition, it does not incorporate future addenda, errata. Please note: as a requirement of the API committee that develops this publication, some errata and addendums may not be available as standalone files, they are simply incorporated into the base publication.
