Pressure piping and process vessels lose wall thickness through corrosion, erosion, and fatigue over years of service. In petrochemical environments, hydrogen sulphide, amine, caustic service, the degradation is faster and the failure modes more dangerous. API 570 requires periodic thickness measurement surveys with documented trending to demonstrate fitness for service.
The question is not whether your assets are degrading. They are. The question is whether you are measuring it systematically, or discovering it during an unplanned shutdown.
Glospech's ultrasonic testing service gives you the data to make informed decisions: retire, repair, monitor, or run-to-next-inspection – before the decision gets made for you by a failure.

Measuring Through Rubber Lagging – Zero Downtime, Full Data
Measuring Through Rubber Lagging – Zero Downtime, Full Data
A mining client needed wall thickness data on conveyor pulleys covered in 20mm rubber lagging. Conventional inspection would have required lagging removal – costing days of downtime, significant labour, and lagging replacement costs.
Using the Cygnus 1 EX Intrinsically Safe Ultrasonic Thickness Gauge with Multiple-Echo technology, Glospech measured through the rubber directly. No stripping. No hot work. No production stoppage.
Results:
Accurate wall thickness readings through 20mm rubber
Zero downtime for stripping or re-lagging
Intrinsically safe execution – suitable for hazardous environments
Full data set for predictive maintenance trending
