Transportable gas cylinders - Refillable welded receptacles of a capacity not exceeding 150 litres - Part 3: Welded carbon steel cylinders made to a design justified by experimental methods

This European Standard specifies minimum requirements concerning material, design, construction and workmanship, procedures and tests at manufacture of refillable transportable welded cylinders made of carbon steel, justified by experimental methods, of water capacities from 0,5 l up to and including 150 l for compressed or liquefied gases and of a test pressure up to 90 bar.
NOTE   This European Standard may also be used as a guideline for cylinders less than 0,5 l water capacity.
This European Standard is primarily intended for industrial gases other than LPG but may also be applied for LPG. However, for dedicated LPG cylinders see EN 14140 [5], prepared by CEN/TC 286.

Ortsbewegliche Gasflaschen - Wiederbefüllbare geschweißte Gefäße mit einem Fassungsraum von nicht mehr als 150 Liter - Teil 3: Flaschen aus geschweißtem Kohlenstoffstahl, ausgelegt nach experimentellen Verfahren

Diese Europäische Norm legt Mindestanforderungen an Werkstoff, Auslegung, Bau und Ausführung, Herstel-lungsverfahren und Herstellungsprüfungen von wiederbefüllbaren, ortsbeweglichen, geschweißten Flaschen aus Kohlenstoffstahl, ausgelegt nach experimentellen Verfahren, mit einem Fassungs¬raum von 0,5 l bis ein-schließlich 150 l für verdichtete und verflüssigte Gase mit einem Prüfdruck bis zu 90 bar fest.

La présente Norme européenne spécifie les exigences minimales relatives au matériau, à la conception, à la
fabrication et à la mise en oeuvre, aux modes de fabrication et aux essais lors de la fabrication des bouteilles

capacités équivalentes en eau comprises entre 0,5 l et 150 l inclus, destinées aux gaz comprimés ou liquéfiés
et soumises à une pression d’épreuve maximale de 90 bar.
NOTE La présente Norme européenne peut également servir de guide en matière de bouteilles de capacité
équivalente en eau inférieure à 0,5 l.
La présente Norme européenne s’applique principalement aux gaz industriels autres que le gaz de pétrole
liquéfié (GPL) mais peut également concerner le GPL. Toutefois, pour les bouteilles à gaz dédiées au GPL,
se reporter à l’EN 14140 [5], élaborée par le comité technique CEN/TC 286.

Introduction The purpose of this European Standard is to provide a specification for the design, manufacture, inspection and approval of welded carbon steel gas cylinders for use in the countries of the CEN members. The specifications given in the present standard establish the methodology to be adopted to demonstrate that a cylinder conforms to the functional requirements demanded, based on experience of materials, design prescriptions, manufacturing processes and controls manufacturing. This European Standard specifies experimental methods and appropriate stress analysis calculations. It does not cover methods exclusively by means of traditional calculation. SIST EN 14638-3:2010
