Globe Valves for Synthesis Gas (Syngas - CO + H₂) Service
Which globe valves configuration suits Synthesis Gas (Syngas - CO + H₂) (CO + H₂), in which material, to which standard — from real service data, with the pitfalls flagged.
Which globe valves for Synthesis Gas (Syngas - CO + H₂)?
Globe Valve (PWHT Cr-Mo, Stellite trim) - Control of syngas flow in reforming circuits - Stellite seat for erosion resistance Typical service window: 20–350 barg (SMR reformer to high-pressure synthesis loop), 200–900°C (reformer outlet) down to ambient in downstream sections.

Governing Standards for Synthesis Gas (Syngas - CO + H₂) Service
What to Avoid in Synthesis Gas (Syngas - CO + H₂) Service
- High-strength steel valves (>90 ksi TS) not validated to NACE MR0103
- Nickel-trim valves in high-CO partial pressure above 150°C
Service Considerations
- API 941 Nelson curve compliance mandatory for all C-Mn and Cr-Mo steel valves in syngas H₂ service
- PWHT (post-weld heat treatment) mandatory for all weld-end syngas valves
- CO monitoring mandatory in control rooms - all valve maintenance on CO lines requires breathing apparatus
- Fugitive emission control critical - CO is odourless and toxic at very low concentrations
