PR NF EN ISO 13703-3, M87-217-3PR (08/2023)

This document specifies requirements for the fabrication, installation, welding, inspection, examination and testing of new metallic piping systems, within the temperature range for materials meeting with the requirements of the ASME B31.3 standard, on fixed and floating offshore production installations and on land-based gas production, processing and liquefaction installations. For piping systems with a pressure class greater than 2500, the requirements of Chapter IX of ASME B31.3 shall be met, as well as the requirements set forth in this standard. This document applies to all pressure components and to any non-pressure component, such as an element of a pipe support, welded directly to a pressure component. This document does not apply to the following: — marine piping systems, for example ballast piping systems, systems covered by classification societies; — metal tubes used for submerged cable bundles; NOTE 1 For welding and examination of these components, reference may be made to ISO 13628-5 or API Spec 17E. — piping systems with a corrosion-resistant coating (either fully coated or mechanically coated) or welded covering, including buttering and associated dissimilar welds; NOTE 2 For the welding and examination of these systems, it is possible to refer to standard DNV-RP-B204. — refractory alloys [except CP Grade 1 (UNS R50250) or Grade 2 (UNS R50400) titanium]; — non-metallic pipe assemblies; — transportation pipeline systems, including flowlines, designed in accordance with a recognized pipeline design code.
