Petroleum and natural gas industries - Pipeline transportation systems - Welding of pipelines (ISO 13847:2013, modified); German and English version prEN 14163:2021

Abstract

This document specifies requirements for the petroleum, petrochemical and natural gas industries, for producing and inspecting girth, branch and fillet welds in the pipeline part of pipeline transportation systems which meet the requirements of ISO 13623:2017 or equivalent.NOTE 1 ISO 13847:2013 refers to the requirements of ISO 13623:2009 or equivalent. At the time of publication of this document, ISO 13623:2009 is superseded by ISO 13623:2017 and reference is made to this edition of ISO 13623 throughout this document. ISO 13623 is modified adopted as EN 14161 to exclude on-land supply systems used by the European gas supply industry from the input of gas into the on-land transmission network up to the inlet connection of gas appliances.This document is applicable to the requirements for welding of carbon and low-alloy steel pipes, and includes guidance for the welding of corrosion-resistant alloy (CRA) and CRA-clad pipelines in Annex A. Application is restricted to pipes with a diameter of 20 mm or more and a wall thickness of 3 mm or more, a specified minimum yield strength of 555 MPa or less, and which are designed not to exceed permissible equivalent stresses as defined in ISO 13623:2017 or equivalent. It is also applicable to welding into pipelines of items such as spools, risers, launchers/receivers, fittings, flanges and pup pieces to pipeline valves. On-land supply systems used by the European gas supply industry from the input of gas into the on-land transmission network up to the inlet connection of gas appliances are excluded from the scope of this document.Guidance for special welding applications is provided in:- Annex B for hyperbaric welding;- Annex C for brazing and aluminothermic welding of anode leads;- Annex D for branch and fillet welding on in-service pipelines.The welding processes covered are shielded metal arc welding (SMAW), gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), gas-shielded flux-cored arc welding (GSFCAW), self-shielded flux-cored arc welding (SSFCAW) and submerged arc welding (SAW).This document is not applicable to flash girth welding, resistance welding, solid-phase welding or other one-shot welding processes, nor to longitudinal welds in pipe or fittings or to the welding of process piping outside the scope of ISO 13623:2017.NOTE 2 Additional requirements might be necessary for the welding of pipeline for particular pipeline operating conditions, for pipelines with a specified yield strength exceeding 555 MPa and for pipelines designed to permissible strain criteria. These can include limitations on maximum hardness or strength, minimum impact toughness values, crack tip-opening displacement, all weld metal tensile testing or bend testing, thermal stress relief, or others. Where appropriate, it is advisable that these additional requirements be added to the requirements of this document in a project-specific supplement.NOTE 3 Annex E specifies additional requirements for the welding of onshore gas supply systems applicable only when located in European member states. Annex F specifies additional requirements for the welding of gas distribution systems applicable only when located in European member states. It is the responsibility of the company to specify the normative applicability of these annexes.
