PR-186-124502-R01 Guidelines for Interpretation and Application of API 1104 Twenty-First Edition

Abstract

The application of requirements contained in many industry codes and standards requires some interpretation by the user and by the regulator who is called upon to enforce their use. The objective of this project was to update the PRCI guidance document for API Standard 1104 - Welding of Pipelines and Related Facilities - for the recently published Twenty-first Edition of the standard and to further develop the document. The use of this document will allow users and regulators to better understand the intent regarding interpretation of some requirements in API 1104, the rationale behind the requirements, and the applicability of the requirements to both conventional and modern high-strength pipelines.
