On-line Safety Valve Testing and Certification
Testing and Certification via Force-Balance Analysis
Riggio Valve Services technology enables safe and economical in-place safety relief valve testing during normal operations with no operational interruption. Yearly re-certification may be achieved without the need for valve removal provided specific prerequisites and qualifications meet code requirements. Test procedures, measurements and analysis facilitate:
- Performing in-place test while boiler is operating
- Determines the as-found set pressure
- Documents adjustments to the valve, if any
- Confirm Valve Set Pressure
- Confirms that three consecutive test results are within tolerance limits
- Generate a Test Report with Test Data
- Re-certify a valve previously certified by Riggio
Riggio is authorized by the National Board of Boiler and Pressure Vessel Inspectors. The procedure is recognized by ASME and can be found in Interpretations I-83-31 and VIII –1-83-350. It is also covered in ASME Section I PG-72.2
