4. MATERIALS

4.1 Materials listed in this document are based on ASTM and ASME.

4.2 Any Material or Size Substitutions shall be approved in writing by a representative of Air Products Cold Box Engineering

4.3 All materials shall be oxygen cleaned (Class AA).

4.4 Cold box connection sizes are DN mm (NPS in).

4.5 Maximum pressure rating for components of Table 1 is 99.3 bar g (1440 psig) at -198° to +38°C (‑325° to +100°F). This pressure rating might be further limited by other components (e.g., valves, regulators), piping specifications, and pressure test procedures.
