Safety and reliability in a pressurised plant environment is paramount
Online Testing and Calibration involves calibrating the set point of the Safety Relief Valves directly in their actual operational working environment.
Online Testing and Calibration is used by Comid technicians in a controlled situation in order to determine the actual lift point or set point of Safety Relief Valves.
Tests are applied to lift the valve at the desired set point. Results are recorded and a test certificate can be produced on site. Should valves fail to lift correctly they can have adjustments made on site or the valve can be marked for removal and overhaul at the next convenient date.
By using Comid’s in-situ testing system for safety valves, √eri-Test, the valve performance can be evaluated whilst the plant and system are operating. There is no need to shut down the plant to enable valve removal for testing.
If the valve is found to be within operational tolerance, the valve can be adjusted if necessary or simply resealed and tagged to denote acceptance.
As the equipment is computerised a test report is produced to demonstrate the performance of the valve.
Valves which do not meet the performance standards can be identified and arrangements made for removal for workshop overhaul at the next convenient plant shutdown
