Valve Integrity Inspections
(PSVs, Manual Valves, Choke Valves, etc)
Monitor Emissions Inc. utilizes Structure Borne Ultrasound to verify valve internal conditions. Unlike Airborne Ultrasound this Ultrasound requires direct contact to upstream and downstream of the valve which allows the shear sound waves to be observed and recorded. This metal to metal contact method has very little impedance to the actual internal ultrasounds allowing internal valve conditions to be verified.
Monitor Emissions Technicians can diagnose internal valve conditions such as:
• Closed valve leaking / passing
• Closed / seated valve
• Open valve
• Internal obstructions
• Comparative reduced flow
• Normal operating conditions
These Ultrasonic Valve Integrity Inspections can be performed on:
• Major Control Valves
• PSVs, checking for leakage or verifying a properly seated PSV
• Wellhead Choke Valves
• Flow Control, Pressure Control, and Fluid Logic Valves
• Steam Traps
Our Ultrasonic Data is then reviewed with our Spectral Analysis Software to build a cohesive report of each tested valve.
Problem valves are tagged with an issue description and digital images of these valves are provided in our reports to allow simple location identification.
Valve condition baselining and continuous monitoring of valve condition can provide condition based data to keep your process flowing as designed.
NOTE: Piping contact and Process flow / pressure is required for this Ultrasound Inspection as turbulence is the key to identifying issues.
