标准摘要
This document specifies requirements for the fabrication, installation, welding, inspection, examination and testing of new, metallic piping systems , within temperature range limits for the materials meeting the requirements of ASME B31 . 3 , on fixed and floating offshore production facilities and onshore production, processing and gas liquefaction plants. For piping systems above pressure class 2500, the requirements of chapter IX of ASME B31 . 3 shall be complied with, in addition to the requirements stated in this standard. This document is applicable to all pressure retaining components and any non-pressure retaining component, such as a member of a pipe support, welded directly to a pressure retaining component. This document is not applicable to the following: — marine-related piping systems, e.g. ballasting piping systems, systems covered by classification societies; — metallic tubing used for subsea umbilical systems; NOTE 1 Reference can be made to ISO 13628 - 5 or API Spec 17E for welding and examination of these components. — piping systems with corrosion resistant cladding (either integrally clad or mechanically lined) or weld overlay, including buttering and associated dissimilar welds; NOTE 2 Reference can be made to DNV-RP-B204 for welding and examination of these systems. — refractory alloys [with exception of CP titanium Grade 1 (UNS R50250) or Grade 2 (UNS R50400)]; — non-metallic piping assemblies; — transportation pipeline systems, including flow-lines, designed in accordance with a recognized pipeline design code.
