This first edition is
43、offered in hopes of bringing relevant state-of-the-art practices to address emerging projects while the task group continues to work on specific problems requiring additional time to research and resolve issues such as welding, CRA cladding, QA, sensors, etc.This document is not intended to be a sta
44、ndalone specification or standard. Rather it is presented as a technical guidance document so that specifications, standards, and recommended practices may reference this document, in part or in total, to augment their operating scope greater than 15,000 psi (103.43 MPa) and/or greater than 350 F (1
45、77 C) wellbore conditions as proffered by API 1PER15K-1. It is necessary that users of this technical report be aware that additional or different requirements which can better suit the demands of a particular service environment, the regulations of a jurisdictional authority or other scenarios not
46、specifically addressed in this technical report, may be applied as required. This document is a technical report and it is not intended to replace sound engineering judgment.In the development of this technical report, the items below are recognized as on-going work for resolution. Many will require
47、 additional discussion and debate, between governing API and ASME standards and their associated design/manufacturing processes. Rather than wait and hold up the publication of the first edition of this technical report, until everything is resolved, the task group elected to release the work it has
48、 accomplished so far, and alert the reader to the work still to be resolved; highlighting that there could be changes to the technical report in subsequent editions.1) Materials QA/QC differences between API, and ASME standards: The task group acknowledges that the QA/QC requirements found in ASME a
49、nd API standards are not aligned, and additionally, may not be aligned between API sub-committees. It is beyond the scope of this technical report to close this gap. As further work is conducted and information comes to light, it is envisioned that the gaps will progress to convergence. It is recommended that these gaps be documented in a FMECA as input to the verification process, and included in the development of a documented design validation program to address the gap.2) Inclusion of external loading: The task group has authored this technical report to provide specific guidance
