LPG equipment and accessories - Welded steel pressure vessels for LPG road tankers - Design and manufacture

This European Standard specifies minimum requirements for materials, design, construction and workmanship procedures, and tests for welded LPG road tanker pressure vessels and their welded attachments manufactured from carbon, carbon/manganese and micro alloy steels.
There is no upper size limit as this is determined by the gross vehicle weight limitation.
This European Standard does not cover pressure vessels for pressure vessel containers.
NOTE 1 In the context of this standard the term "road tanker" is understood to mean "fixed tanks" and "demountable tanks" as defined in ADR.
NOTE 2 The equipment for the pressure vessels and the inspection and testing after assembly is covered by EN 12252 and EN 14334, respectively.
NOTE 3 The design type of the road tanker is subject to approval by the competent authority, as required by ADR.

Flüssiggas-Geräte und Ausrüstungsteile - Geschweißte Druckbehälter aus Stahl für Straßentankwagen für Flüssiggas (LPG) - Auslegung und Herstellung

Diese Europäische Norm legt Mindestanforderungen an Werkstoffe, Auslegung, Bau und Ausführungsverfahren sowie Prüfungen für geschweißte Druckbehälter für Straßentankwagen für Flüssiggas (LPG, en: liquefied petroleum gas) und deren angeschweißtes Zubehör fest, die aus Kohlenstoffstahl, Kohlenstoff Manganstahl und mikrolegiertem Stahl hergestellt werden.
Es besteht keine Obergrenze für die Größe, da diese durch die Begrenzung der Bruttomasse des Fahrzeuges festgelegt wird.
Diese Europäische Norm gilt nicht für Druckbehälter für Tankcontainer.
ANMERKUNG 1   Im Sinne dieser Norm ist der Begriff „Straßentankwagen“ entsprechend der Definition im ADR als „fest verbundene Tanks“ und „Aufsetztanks“ zu verstehen.
ANMERKUNG 2   Die Ausrüstung der Druckbehälter sowie die Inspektion und Prüfung nach dem Zusammenbau ist durch EN 12252 bzw. EN 14334 abgedeckt.
ANMERKUNG 3   Das Baumuster des Straßentankwagens unterliegt entsprechend der Anforderung des ADR einer Zulassung durch die zuständige Behörde.

Équipements pour GPL et leurs accessoires - Réservoirs sous pression en acier soudés des camions-citernes pour GPL - Conception et construction

La présente Norme européenne spécifie les exigences minimales relatives aux matériaux, à la conception, à la construction et à la qualité d’exécution, ainsi que les essais des réservoirs sous pression soudés de camions-citernes utilisés pour le transport du GPL et de leurs accessoires soudés fabriqués en acier au carbone, en acier au carbone/manganèse et en acier micro-allié.
La présente norme ne définit pas de taille limite supérieure pour le réservoir étant donné que celle-ci sera déterminée par la limite du poids total en charge du véhicule.
La présente Norme européenne ne couvre pas les réservoirs sous pression destinés à des conteneurs-citernes.
NOTE 1   Dans le cadre de la présente norme, le terme « camion-citerne » signifie « réservoirs fixes » et « réservoirs démontables » comme définis dans l'ADR.
NOTE 2   L'équipement des camions-citernes et leurs contrôles et essais après construction sont couverts respectivement par les normes EN 12252 et EN 14334.
NOTE 3   Le mode de conception du camion-citerne est sujet à l'approbation de l'autorité compétente comme prévu dans l'ADR.

Overview

EN 12493:2013+A1:2014/prA2 - published by CEN - specifies minimum requirements for the design and manufacture of welded steel pressure vessels for LPG road tankers. It covers vessels and welded attachments made from carbon, carbon/manganese and micro‑alloy steels used for LPG transport by road (fixed and demountable tanks as defined by ADR). The standard sets requirements for materials, construction, workmanship and testing; it does not apply to pressure vessel containers. Vehicle size is governed by gross vehicle weight limits rather than the standard.

Key topics and requirements

• Scope and applicability
  • Intended specifically for LPG; for other liquefied gases see EN 14025.
  • Design type subject to competent authority approval under ADR.
• Materials and construction
  • Acceptable steels: carbon, carbon/manganese and micro‑alloy steels.
  • Minimum shell and end thickness calculations are aligned with ADR requirements.
• Welding and personnel qualification
  • Welders and welding operators must be qualified (reference moved from EN 287‑1 to EN ISO 9606‑1 and EN ISO 14732).
  • Welding procedures to conform to EN ISO 15614‑1 where weld metal is deposited during repairs.
• Non‑destructive testing (NDT)
  • Radiographic testing requirements updated to EN ISO 5579 and EN ISO 17636‑1/2 (class B).
  • Radiographic image quality to conform to EN ISO 19232‑1/2.
• Design calculations and fittings
  • Cylindrical shell, dished ends and nozzle reinforcement rules; minimum thickness not less than ADR-calculated values.
  • Doubler/compensation plates must have vent holes or test sockets.
  • Surge plate spacing limited (distance between surge plates ≤ 4 m).
• Testing and records
  • Hydraulic test safety precautions and manufacturer record‑keeping (welders list, approvals per EN ISO 9606‑1).
• Environmental and normative updates
  • Standard to be read with CEN/TS 16765 for environmental considerations; bibliography includes EN 14025 and related standards.

Applications and users

This standard is essential for:

• Manufacturers and fabricators of LPG road tankers
• Design engineers responsible for pressure vessel design and CAD calculations
• Quality and welding supervisors ensuring compliance with welding and NDT procedures
• Certification bodies and competent authorities performing ADR approvals
• Fleet operators, maintenance and repair workshops involved in vessel repairs and periodic testing

Related standards (selected)

• EN 12252, EN 14334 - equipment and inspection/testing after assembly
• EN 14025 - metallic pressure tanks for other liquefied gases
• EN ISO 9606‑1 - welder qualification
• EN ISO 5579, EN ISO 17636‑1/2 - radiographic testing
• EN ISO 19232‑1/2 - radiograph image quality
• EN 13445‑3 - compensation calculations for openings
• CEN/TS 16765 - environmental considerations

Keywords: EN 12493, LPG road tankers, welded steel pressure vessels, design and manufacture, ADR, NDT, welder qualification, radiographic testing.
