Critical Valve Requirements

ASTM G93 / CGA G-4.1 oxygen cleaning - all valves for LOX/GOX service must be degreased with approved solvents, then passivated; verified by UV light and/or white glove test; sealed in nitrogen-purged bags until installation
EIGA Doc 13 (European Industrial Gases Association) - comprehensive oxygen safety standard; defines material compatibility, ignition mechanisms, and design requirements for oxygen valves
No PTFE in high-pressure oxygen service (> 30 bar GOX) - PTFE can ignite in high-velocity O₂; use PCTFE or metal-to-metal seats instead; PTFE acceptable for low-pressure (<30 bar) LOX
No brass, bronze, or copper alloys - acceptable for low-pressure oxygen, but ASU practice avoids them entirely due to particle contamination risk
Extended bonnet per BS 6364 - minimum 350 mm bonnet extension for valves below −29°C to keep packing above cryogenic zone
Impact testing - all cryogenic valve components must pass Charpy V-notch impact test at −196°C per ASTM A370

What certifications are required for air separation units (asu) valves in Cartagena?
For air separation units (asu) in Cartagena, the applicable standards are: ASTM G93 (Oxygen Cleaning), EIGA Doc 13 (Oxygen Safety), BS 6364 (Cryogenic Valves), ASME B16.34, ISO 21011 (Cryogenic Valves), CGA G-4.1 (O₂ Cleaning USA), API 598.

Express dispatch available for urgent site requirements. Contact us at +91-9979774557 or sales@vajravyuh.com with your specification and required delivery date.
What is ASTM G93 oxygen cleaning and is it mandatory for all ASU valves?
ASTM G93 (Standard Practice for Cleaning Methods and Cleanliness Levels for Material and Equipment Used in Oxygen-Enriched Environments) defines the degreasing, rinsing, and verification process for components that will be in contact with oxygen. For LOX and GOX service in ASUs, ASTM G93 cleaning is mandatory - trace hydrocarbons or particles can ignite in an oxygen-rich environment. The process involves solvent degreasing (usually with non-flammable chlorinated solvents or approved alternatives), hot DI water rinse, oven drying, UV light inspection, white-glove testing, and sealing in nitrogen-purged polyethylene bags for shipment.
Why can't I use PTFE seats in high-pressure oxygen valves?
PTFE (polytetrafluoroethylene) is generally oxygen-compatible at low pressures and low flow velocities. However, above approximately 30 bar GOX, PTFE can ignite through frictional heating from high-velocity gas impingement or particle impact ignition - a mechanism unique to oxygen service. EIGA Doc 13 and CGA G-4.1 restrict PTFE in high-pressure oxygen to specific designs with defined velocity limits. PCTFE (polychlorotrifluoroethylene) is the standard alternative - it has a higher ignition temperature than PTFE and is the seat material of choice for high-pressure LOX and GOX valves above 30 bar.
