Hot rolled weldable steel bars for pressure purposes with specified elevated temperature properties

This European Standard specifies the technical delivery conditions for hot rolled weldable steel bars for the construction of pressure equipment for use at elevated temperatures.
The general technical delivery conditions in EN 10021 also apply to products supplied in accordance with this European Standard.
NOTE   Once this European Standard is published in the Official Journal of the European Union (OJEU) under Directive 97/23/EC, presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 97/23/EC is limited to technical data of materials in this European Standard and does not presume adequacy of the material to a specific item of equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of this specific item of equipment to verify that the ESRs of the Pressure Equipment Directive 97/23/EC are satisfied, needs to be done.

La présente Norme européenne spécifie les conditions techniques de livraison des barres laminées à chaud en aciers soudables pour la construction des appareils à pression utilisés à des températures élevées avec les épaisseurs données au Tableau 5.
Les conditions techniques générales de livraison de l'EN 10021 s'appliquent également aux produits livrés conformément à la présente Norme européenne.
NOTE   Dès lors que la présente Norme européenne est publiée dans le Journal Officiel de l’Union européenne (JO) en lien avec la Directive 2014/68/CE, la présomption de conformité avec les exigences essentielles de sécurité de la Directive 2014/68/CE se limite aux données techniques relatives aux matériaux spécifiés dans la présente Norme européenne et ne suppose pas l’adéquation des matériaux avec un appareil en particulier. Par conséquent, il doit être procédé à l’évaluation des données techniques spécifiées dans la présente norme de matériaux par rapport aux exigences relatives à la conception de cet équipement spécifique, afin de vérifier que les exigences essentielles de sécurité de la Directive relative aux équipements sous pression sont satisfaites.

Vroče valjane jeklene palice, primerne za varjenje tlačnih posod, s specificiranimi lastnostmi pri povišanih temperaturah

Ta evropski standard določa tehnične dobavne pogoje za vroče valjane jeklene palice za konstrukcijo tlačne opreme za uporabo pri povišanih temperaturah.
Splošni tehnični dobavni pogoji v standardu EN 10021 se uporabljajo tudi za proizvode, dobavljene v skladu s tem evropskim standardom.
OPOMBA:   Ko bo ta evropski standard objavljen v Uradnem listu Evropske unije (OJEU) v okviru Direktive 97/23/ES, bodo zagotovila o skladnosti z osnovnimi varnostnimi zahtevami (ESR) Direktive 97/23/ES omejena na tehnične podatke o materialih, navedene v tem evropskem standardu, standard pa ne bo zagotavljal ustreznosti materiala za določen element opreme. Zato bo potrebno oceniti tehnične podatke, podane v tem standardu za materiale, glede na zahteve zasnove določenega elementa opreme, da se zagotovi, da so izpolnjene osnovne varnostne zahteve Direktive 97/23/ES o tlačni opremi.

Overview

EN 10273:2016 is a CEN European Standard that defines the technical delivery conditions for hot rolled weldable steel bars for pressure purposes with specified elevated temperature properties. It covers the manufacture, delivery condition, chemical composition, mechanical properties and testing requirements for steel bars and rods intended for construction of pressure equipment that will operate at elevated temperatures. The general delivery rules in EN 10021 also apply. Note: presumption of conformity to the Pressure Equipment Directive (2014/68/EU) is limited to the material data in this standard; equipment designers must verify material adequacy for specific items.

Key topics and requirements

• Scope and classification
  • Applies to hot-rolled, weldable steel bars/rods for pressure equipment used at elevated temperatures. Steel grades include non-alloy and alloy steels (examples: P235GH, 16Mo3, P355NH).
• Delivery conditions
  • Specifies standard delivery conditions (see Table 5) including normalizing, quenching & tempering (QT), or untreated where agreed. Includes guidance on normalizing rolling and heat treatment options.
• Chemical composition
  • Cast and product analysis requirements; allowable deviations between cast and product analyses are defined (see Tables 2 and 3). Option to set maximum carbon equivalent for weldability concerns.
• Mechanical properties
  • Tensile strength, proof strength (Rp0.2) and verification at room and specified elevated temperatures. Impact energy requirements and testing temperatures (Charpy) are included.
• Weldability and heat treatment
  • Requirements for weldability data and optional delivery of suitable welding conditions. Annex A provides heat treatment guidelines for select grades.
• Inspection and testing
  • Defines types of inspection documents (EN 10204), sampling frequency, and required tests: chemical analysis, tensile tests (EN ISO 6892‑1/2), Charpy impact (EN ISO 148‑1), ultrasonic testing (EN 10308) and other NDT as agreed.
• Marking and documentation
  • Rules for marking, traceability and inspection certificates to accompany deliveries.

Applications and who uses this standard

• Typical users:
  • Manufacturers of pressure vessels, boilers, heat exchangers and piping for high-temperature service
  • Steel mills and bar producers specifying production and delivery requirements
  • Procurement and quality engineers specifying material for pressure equipment
  • Welding engineers, fabricators and third-party inspectors responsible for weldability and testing
  • Design engineers verifying material data against the Pressure Equipment Directive (PED)
• Practical applications:
  • Specifying material for elevated-temperature service in petrochemical, power generation, refinery and industrial process equipment where strength and creep/rupture behaviour at temperature are critical.
