LANL MASTER SPECIFICATION

The designer is encouraged to review ASME B31.3; DOE Handbook 1132, Design Considerations; and LANL Engineering Standards Manual Chapters 13–Welding, Joining,& NDE, and 17–Pressure Safety.

This Section was developed to meet the requirements for ASME B31.3-2016, Fluid Service CategoryD and Normal except for oxygen and cryogenic service. Use of this section for a different fluid service or edition of the ASME code will require a detailed review of the code and ESM Chapter17. See ASME B31.3, Appendix M, Fig. M300 for classifying fluid services.

This template must be edited for each project. In doing so, specifier must add job-specific requirements. Brackets are used in the text to indicate designer choices or locations where text must be supplied by the designer. Once the choice is made or text supplied, remove the brackets.This section must also be edited to delete requirements for processes, items, or designs that are not included in the project -- and specifier’s notes such as these.

Please contact the pressure safety SME on the ESM web page with suggestions for improvements.

When assembling a specification package, include applicable specifications from all Divisions, especially Division 1, General requirements.

This section was developed for ML-4 projects. For ML-1, 2, and 3 applications, additional requirements might be necessary if increased confidence in procurement or execution is desired, and independent review is necessary. See ESM Chapter 1 Section Z10 specifications and quality sections.

This piping specification is primary written for use inside a building. When used outside they should normally be covered in the site utilities series (Div 33). The utility sections may reference this section.

This section must be augmented when ESM Chapters, like Chapter 10,Hazardous Processes,drive additional requirements (e.g., Category M).

Seismic: In order to edit this section for job-specific seismic requirements, refer to author notes that begin with “Seismic.” Also, see the Seismic Specification Guide for Process Piping(soon-to-be posted on LANL specs webpage) for guidance on properly editing this section.
