Recent Changes in Code Requirements for Repair of In-Service Pipelines by Welding

Abstract

The API code requirements for repair of in-service pipelines by welding were recently up-dated. The 19th edition of API 1104 - Welding of Pipelines and Related Facilities - includes a new appendix (Appendix B) titled In-Service Welding, which is intended to eventually replace API 1107 - Pipeline Maintenance Welding Practices. Work is also presently underway to up-date the requirements for weld deposition repair in ASME B31.8 - Gas Transmission Systems. This paper reviews the rationale behind these changes and provides a brief summary of their primary features.Copyright © 2000 by ASME
