Petroleum, petrochemical and natural gas industries - Calculation of heater-tube thickness in petroleum refineries (ISO 13704:2022)

This document specifies the requirements for the procedures and design criteria used for calculating the required wall thickness of new tubes and associated component fittings for petroleum, petrochemical and natural gas industries. These procedures are appropriate for designing tubes for service in both corrosive and non-corrosive applications. These procedures have been developed specifically for the design of refinery and related process-fired heater tubes (direct-fired, heat-absorbing tubes within enclosures). These procedures are not intended to be used for the design of external piping.
This document does not give recommendations for tube retirement thickness. A technique for estimating the life remaining for a heater tube is described
This document is a supplement to API 530, 7th edition (2015) including addendum 1 and addendum 2, the requirements of which are applicable with the exceptions specified in this document.

Le présent document spécifie les exigences et donne des recommandations pour des méthodes et des critères de conception utilisés pour calculer l’épaisseur de paroi requise de tubes neufs et de raccords composants associés pour les industries du pétrole, de la pétrochimie et du gaz naturel. Ces méthodes sont appropriées pour concevoir des tubes destinés à un service dans des applications corrosives et non corrosives. Ces méthodes ont été développées spécifiquement pour la conception des raffineries et des tubes de fours à brûleurs de procédé associés (à brûleurs directs, tubes absorbant la chaleur au sein d’enceintes). Ces méthodes ne sont pas prévues pour être utilisées pour la conception de tuyauterie extérieure.
Le présent document ne donne aucune recommandation concernant l'épaisseur de retrait de tubes. Il décrit une technique pour l'estimation de la durée de vie restante d'un tube de four.

Petrokemična industrija ter industrija za predelavo nafte in zemeljskega plina - Izračun debeline grelne cevi v rafinerijah nafte (ISO 13704:2022)

Ta dokument določa zahteve za postopke in merila za načrtovanje, ki se uporabljajo za izračun zahtevane debeline sten novih cevi in pripadajočih sestavnih delov za petrokemično industrijo ter industrijo za predelavo nafte in zemeljskega plina. Ti postopki so primerni za načrtovanje cevi za uporabo tako v korozivnem kot nekorozivnem okolju. Oblikovani so bili posebej za načrtovanje grelnih cevi v rafinerijskih in sorodnih procesih (cevi, ki so neposredno izpostavljene ognju in absorbirajo toploto znotraj ohišja). Niso namenjeni za uporabo pri načrtovanju zunanjih cevi. Ta dokument ne podaja priporočil glede debeline cevi ob koncu njihove življenjske dobe. Opisana je tehnika za ocenjevanje preostale življenjske dobe grelne cevi. Ta dokument dopolnjuje standard API 530, sedmo izdajo (2015), vključno z dodatkoma 1 in 2, katerega zahteve se uporabljajo za izjeme, določene v tem dokumentu.

Overview

EN ISO 13704:2022 - Petroleum, petrochemical and natural gas industries - Calculation of heater‑tube thickness in petroleum refineries - specifies design procedures and criteria for calculating the required wall thickness of new heater tubes and associated fittings used in petroleum refineries. It is focused on process‑fired heater tubes (direct‑fired, heat‑absorbing tubes within enclosures) for both corrosive and non‑corrosive service. This edition (third, 2022) supplements API Std 530 (7th edition, 2015) including Addenda 1 and 2 and updates material allowable stresses in line with the latest industry guidance.

Key topics and technical requirements

• Scope and applicability
  • Calculation procedures for new heater‑tube wall thickness and associated component fittings.
  • Intended specifically for refinery and related process‑fired heater tubes; not intended for external piping design.
• Design criteria
  • Uses the requirements of API Std 530 (7th edition) as the baseline; where API 530 applies, EN ISO 13704 provides supplemental or alternative provisions specific to heater tubes.
  • Allows design for both corrosive and non‑corrosive operating conditions.
• Material allowable stresses
  • Updated allowable stress values for some materials in accordance with WRC Bulletin 541 (3rd edition, Aug 2020).
• External pressure / tube under vacuum
  • Where API 530 refers to ASME BPVC Section VIII, Division 1 for external pressure considerations, EN ISO 13704 specifies the EN 13445 series as the applicable reference.
• Tube life estimation
  • The standard does not prescribe retirement thickness, but it describes a technique for estimating remaining life of heater tubes to support inspection and fitness‑for‑service planning.

Practical applications

• Designing and specifying heater tubes and fittings for:
  • Crude heaters and process‑fired tubular furnaces in refineries
  • Petrochemical process heaters and heat‑absorbing tube bundles
• Material selection and minimum wall thickness calculations for new installations to ensure mechanical integrity, safety and regulatory compliance.
• Supporting inspection planning and remaining life estimation for asset integrity teams (note: retirement thickness guidance is outside the scope).

Who should use this standard

• Mechanical and process design engineers working in refineries and petrochemical plants
• Inspection, maintenance and asset integrity engineers assessing heater tubes
• Materials engineers selecting alloys for heater tube service
• Standards compliance and regulatory teams within the petroleum, petrochemical and natural gas industries

Related standards

• API Std 530, 7th edition (2015) with Addenda 1 and 2 - baseline calculation methodology
• EN 13445 (Unfired pressure vessels) - used for external pressure rules where referenced
• WRC Bulletin 541 - referenced for updated allowable stress values

Keywords: EN ISO 13704:2022, heater tube thickness, API 530, refinery heater tubes, tube life estimation, petrochemical standards, EN 13445.
