Welded steel tubes for pressure purposes - Technical delivery conditions - Part 1: Electric welded and submerged arc welded non-alloy steel tubes with specified room temperature properties

This document specifies the technical delivery conditions for qualities TR1 and TR2 of electric welded and submerged arc welded tubes of circular cross section, with specified room temperature properties, made from non-alloy quality steel.
NOTE 1   Quality TR2 is intended to support the essential requirements of EU Directive 2014/68/EU in respect of pressure equipment with specified room temperature properties (see Table 5).
NOTE 2   Once this standard is published in the Official Journal of the European Union (OJEU), presumption of conformity to the Essential Safety Requirements (ESR) of Directive 2014/68/EU is limited to the technical data for the materials in this standard and does not presume adequacy of the material for a specific item of pressure equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of a specific item of equipment to verify that the ESRs of the Pressure Equipment Directive are satisfied, needs to be done by the designer or manufacturer of the pressure equipment, taking also into account any subsequent processing procedures which may affect properties of the base materials.

ANMERKUNG 1 Die Güte TR2 ist vorgesehen zur Unterstützung der grundlegenden Anforderungen der EU-Richtlinie 2014/68/EU bezüglich Druckgeräten mit festgelegten Eigenschaften bei Raumtemperatur (siehe Tabelle 5).
ANMERKUNG 2 Nach Veröffentlichung dieser Norm im EU-Amtsblatt (ABl.) ist die Annahme ihrer Konformität mit den grundlegenden Sicherheitsanforderungen (ESR) der Richtlinie 2014/68/EU auf die technischen Daten von Werkstoffen in dieser Norm beschränkt, und es darf nicht angenommen werden, dass damit die Eignung des Werkstoffs für ein bestimmtes Ausrüstungsteil festgestellt ist. Folglich müssen die in dieser Werkstoffnorm angegebenen technischen Parameter im Hinblick auf die konstruktiven Anforderungen dieses bestimmten Ausrüstungsteils ermittelt werden, um damit zu verifizieren, dass den ESR der Druckgeräterichtlinie entsprochen wird. Dies muss durch den Ausleger oder den Hersteller der Druckgeräte geschehen, der auch den nachfolgenden Herstellungsprozess berücksichtigen muss, der die Eigenschaften des Grundmaterials verändern kann.

NOTE 2   Dès lors que la présente Norme européenne est publiée dans le Journal Officiel de l’Union européenne (JOUE) en lien avec la Directive 2014/68/UE, la présomption de conformité avec les exigences essentielles de sécurité de la Directive 2014/68/UE se limite aux données techniques des matériaux spécifiées dans la présente Norme européenne et ne suppose pas l’adéquation des matériaux avec un appareil en particulier. Par conséquent, l’évaluation des données techniques spécifiées dans la présente norme de matériaux par rapport aux exigences de conception d’un équipement spécifique, pour vérifier que les exigences essentielles de sécurité de la Directive 2014/68/UE soient satisfaites, doit être effectuée par le concepteur ou le fabricant de l’équipement sous pression, en tenant aussi compte de toutes les procédures ultérieures de fabrication qui peuvent affecter les propriétés du matériau de base.

Overview

EN 10217-1:2019 specifies the technical delivery conditions for electric welded (EW) and submerged arc welded (SAW) non‑alloy steel tubes for pressure purposes. It covers circular cross‑section tubes with specified room temperature properties, defining two material qualities - TR1 and TR2. The standard supports conformity assessment under EU Directive 2014/68/EU (Pressure Equipment Directive) for TR2 material data, while clarifying that designers and manufacturers must still verify material adequacy for specific pressure equipment and any post‑processing effects.

Key topics and requirements

• Scope & classification: Defines tube types, quality grades (TR1, TR2) and designation rules.
• Manufacturing requirements: Steelmaking, tube forming and welding (EW, SAW), and delivery conditions.
• Chemical composition & analysis: Cast and product analysis requirements to ensure base‑material chemistry.
• Mechanical properties: Tensile requirements, impact testing where applicable, and room‑temperature property criteria.
• Weld and surface integrity: Visual inspection, internal soundness, weld seam criteria and surface condition requirements.
• Inspection & testing: Sampling, test units, verification of test methods (tensile, flattening, drift expanding, leak‑tightness, NDT).
• Non‑Destructive Testing (NDT): Requirements for NDT personnel and methods for EW/HFW and SAW tubes.
• Dimensional controls: Diameters, wall‑thicknesses, lengths, mass and tolerance specifications.
• Marking, documentation & inspection certificates: Mandatory marking, additional marking options and inspection documents.
• Welding procedure qualification: Annex A details SAW weld procedure qualification and sample tests for TR2 production.

Applications and users

EN 10217-1:2019 is intended for organizations involved in pressure equipment and piping where welded steel tubes are used, including:

• Manufacturers of welded steel tubes (EW/SAW)

1 Scope
This document specifies the technical delivery conditions for qualities TR1 and TR2 of electric welded
and submerged arc welded tubes of circular cross section, with specified room temperature
properties, made from non-alloy quality steel.
NOTE 1 Quality TR2 is intended to support the essential requirements of EU Directive 2014/68/EU in respect
of pressure equipment with specified room temperature properties (see Table 5).
NOTE 2 Once this standard is published in the Official Journal of the European Union (OJEU), presumption of
conformity to the Essential Safety Requirements (ESR) of Directive 2014/68/EU is limited to the technical data
for the materials in this standard and does not presume adequacy of the material for a specific item of pressure
equipment. Consequently, the assessment of the technical data stated in this material standard against the design
requirements of a specific item of equipment to verify that the ESRs of the Pressure Equipment Directive are
satisfied, needs to be done by the designer or manufacturer of the pressure equipment, taking also into account
any subsequent processing procedures which may affect properties of the base materials.

The submerged arc weld of SAW tubes shall be made using at least one weld run on the inside and one
weld run on the outside of the tube.
The strip used for the manufacture of SAWH tubes shall have a width of not less than 0,8 times or more
than 3,0 times the outside diameter of the tube.
The finished tubes shall not include the welds used to join together the strip or plate prior to forming,
except for SAWH tubes where this is permitted only when the welding procedure for the weld joining
the strip or plate has been qualified in accordance with Annex A and has also been subjected to the
same inspection and testing regime as the helical pipe welds (see 11.11.4).
7.2.2 Tube production welding shall be carried out by qualified personnel in accordance with
documented procedures. For tubes to be used in pressure equipment under European legislation,
manufacturers shall employ an established procedure for the approval of welding operatives.
