Governing Standards for Compressed Air Service
What to Avoid in Compressed Air Service
- Applies to this type: Large-bore butterfly valves in pulsating or compressor discharge service without surge analysis
- Cast iron valves in instrument air service (risk of internal corrosion contaminating air supply)
- Plastic-bodied valves above 10 bar or in environments where UV degradation is a risk
Service Considerations
- Instrument air must be oil-free and dry - oil contamination damages positioners and instruments
- Moisture separators and filters required at all panel and instrument connection points
- Receiver tank safety valves must be IBR-certified for vessels >0.5 m² heating surface
- Compressed air lines carrying > 7 bar must be inspected per Factories Act and Pressure Vessel regulations
