Overview

EN 13458-2:2002 is a CEN European Standard for cryogenic vessels - specifically static vacuum insulated vessels - covering design, fabrication, inspection and testing. It applies to stationary cryogenic storage vessels designed for a maximum allowable pressure greater than 0.5 bar and for the range of cryogenic fluids defined in EN 13458‑1. The standard excludes vessels designed for toxic fluids and may be used as a guidance document for vessels with maximum allowable pressure ≤ 0.5 bar.

Key topics and technical requirements

• Design principles
  • Options for design by calculation, pressure-strengthening (for austenitic stainless steels) or experimental verification.
  • Requirements for design documentation, load cases and combinations (pressure, liquid head, supports, thermal and external loads).
  • Special provisions for material selection and use of cold properties (see Annex E).
• Materials and metallurgy
  • Material selection and toughness requirements referenced (EN 1252 series).
  • Additional requirements for 9% Ni steels given in Annex B.
• Fabrication
  • Welding qualifications, procedures and joint details; acceptance criteria referenced to relevant EN welding and brazing standards.
  • Minimum wall thickness rules and provisions for supports, nozzles and joints.
• Inspection and testing
  • Non‑destructive testing (radiography, radioscopy) and NDT personnel qualifications.
  • Pressure testing, proof testing and the use of relief devices (Annex D and I), bursting discs and relief plates.
• Normative vs informative annexes
  • Normative: A (elastic stress analysis), B (9% Ni steel), E (cold properties), G (flammable fluids), I (outer jacket relief devices), K (base materials).
  • Informative: C (pressure strengthening guidance), F (weld details), H, J, ZA (EU Directives relation).

Practical applications and users

• Primary applications
  • Design and production of stationary cryogenic storage tanks for industrial gases and other cryogenic fluids covered by EN 13458‑1.
  • Commissioning, inspection and routine testing procedures for installed vessels.
• Who uses this standard
  • Mechanical engineers and designers of cryogenic storage systems.
  • Fabrication shops and welding coordinators manufacturing vacuum insulated vessels.
  • Inspection bodies, NDT technicians and testing laboratories.
  • Plant safety engineers, procurement and compliance teams ensuring PED/EU directive alignment.

Related standards

• EN 13458‑1 (Fundamental requirements)
• EN 1252‑1 / EN 1252‑2 (Material toughness at low temperatures)
• EN 13445 (Unfired pressure vessels)
• EN 13648 series (Safety devices / discharge sizing)
• EN 1626 (Valves for cryogenic service)
• Relevant welding, NDT and materials standards cited in EN 13458‑2

This standard is essential for anyone involved in the lifecycle of static vacuum insulated cryogenic vessels and ensures consistency, safety and regulatory compliance in design, manufacture and testing.

K20K shall be the minimum value at 20 °C taken from the material standard, (see annex J).4.3.2.3.3
KtThe permissible value of K shall be determined for the material at the operating temperature corresponding to thesaturation temperature at the maximum allowable pressure of the vessel, of the contained cryogenic fluid. Thevalue of K and E shall be determined from the material standard (see EN 10028-7:2000, annex F for austeniticstainless steels) or shall be guaranteed by the material manufacturer.4.3.2.4 Safety factors S, TS, pS and kSSafety factors are the ratio of material property K over the maximum allowable stress.a) internal pressure (pressure on the concave surface):¾ at vessel maximum allowable pressureS = 1,5¾ at vessel proof test pressureTS = 1,05b) external pressure (pressure on the convex surface):¾ cylinders and conespS = 1,6kS = 3,0¾ spherical regionpS = 2,4kS = 3,0 + 0,002 R/s¾ knuckle regionpS = 1,84.3.2.5 Weld joint factors vFor internal pressure (pressure on the concave surface)v = 0,85 or 1,0 (see clause 6, Table 6).For external pressure (pressure on the convex surface)v = 1,0.
