Petroleum, petrochemical and natural gas industries - Calculation of heater-tube thickness in petroleum refineries
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.
Industries du pétrole, de la pétrochimie et du gaz naturel — Calcul de l'épaisseur des tubes de fours de raffineries de pétrole
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. Le présent document complète l’API 530, 7e édition (2015), y compris l’addendum 1 et l’addendum 2, dont les exigences sont applicables selon les exceptions spécifiées dans le présent document.

Overview
ISO 13704:2022 specifies requirements and design criteria for the calculation of required wall thickness of new heater tubes and associated fittings used in petroleum, petrochemical and natural gas industries. This standard focuses on refinery and process-fired heater tubes (direct-fired, heat-absorbing tubes within enclosures) for both corrosive and non‑corrosive services. It is a supplement to API Std 530 (7th edition, 2015) including addenda and updates certain provisions to align with international practice.
Key clarifications in this edition include references to updated allowable stress values and the use of EN 13445 for external pressure cases in place of ASME BPVC Section VIII, Division 1 where specified. ISO 13704:2022 does not provide retirement thickness recommendations, but it does describe a technique for estimating remaining life of heater tubes.
Key Topics
- Scope and applicability: Design of heater tubes for petroleum refineries; not intended for external piping design.
- Wall thickness calculation procedures: Requirements and procedural supplements to API 530 for design of new tubes and fittings.
- Corrosion and service conditions: Guidance for both corrosive and non‑corrosive applications and associated safety considerations.
- External pressure: Use of EN 13445 series where API 530 references ASME BPVC for external pressure limitations.
- Life estimation: Technique provided to estimate remaining life of heater tubes (note: retirement criteria are not prescribed).
- Material allowable stresses: Updates reflecting the latest referenced data (e.g., WRC bulletin updates noted in the foreword).
Applications
ISO 13704:2022 is intended for engineers, designers, maintenance planners and safety professionals involved in:
- Design and specification of heater-tube assemblies in oil refineries and related process plants.
- Engineering reviews that ensure compliance with international calculation procedures when API 530 is the baseline.
- Fitness-for-service assessments where remaining life estimation of heater tubes informs inspection and turnaround planning.
- Integrating heater-tube calculations into procurement and manufacturing specifications for new tubes and associated fittings.
Benefits include consistent, internationally-aligned calculation methodology, improved safety and compliance with industry practice, and clearer guidance when reconciling API 530 requirements with European pressure vessel rules.
Related Standards
- API Std 530, 7th edition (2015) and its Addenda 1 and 2 - ISO 13704 acts as a supplement to these documents.
- EN 13445 (all parts) - referenced for external pressure design where ISO 13704 replaces an ASME BPVC reference.
For implementation, consult the full ISO 13704:2022 text and the cited normative references to ensure aligned design decisions and adherence to specific procedural requirements.
