Overview

EN 13293:2002 is a CEN European Standard that specifies minimum requirements for the design, construction, material selection, manufacture and testing of refillable, transportable, seamless normalized carbon–manganese steel gas cylinders. It covers cylinders of water capacity up to 0.5 litre for compressed, liquefied and dissolved gases and up to 1 litre for carbon dioxide. The standard focuses on small refillable cylinders manufactured from normalized carbon–manganese steel with tensile strength (Rm) below 850 MPa.

Key topics and technical requirements

• Scope and materials: Only normalized carbon–manganese steels are covered; steels must be killed and compatible with the intended gas (see EN ISO 11114-1). Chemical composition limits and tolerances for C, Mn, Si, Cr, S and P are defined and cast analyses are required.
• Heat treatment: Normalizing is mandatory; controlled hot forming is acceptable under defined conditions. Reheat after failures is limited and specified.
• Design fundamentals: Wall thickness is calculated from the guaranteed yield stress (Re) and the hydraulic test pressure (ph). The standard limits Re/Rg and sets minimum absolute thickness limits (including an absolute minimum a = 1.5 mm).
• End geometry: Minimum dimensional recommendations for convex (domed) and concave ends, knuckle radii and progressive thickness transitions to ensure favorable stress distribution.
• Manufacturing and workmanship: Identification of steel cast, records, marking and prevention of defects; guidance on acceptance/rejection of manufacturing defects (informative Annex A).
• Testing and conformity: Requirements include new-design tests, batch tests, and tests on every cylinder (hydraulic/burst, yield, cyclic pressure testing). Certificates and records are required; guidance on conformity assessment is given (Annex B and C). The standard is referenced for RID/ADR transport regulations.

Applications and users

Who uses EN 13293:

• Cylinder manufacturers and designers of small seamless refillable gas cylinders
• Quality and test laboratories performing hydraulic, burst and batch tests
• Conformity assessors and regulatory authorities (transport safety, ADR/RID)
• Procurement, maintenance and inspection teams for industries using small refillable cylinders

Practical applications:

• Specification and approval of small refillable cylinders for compressed, liquefied and dissolved gases, and carbon dioxide service (up to the prescribed volumes)
• Design verification, material control and production quality assurance for manufacturers
• Supporting conformity evidence for transport and safety compliance
