Ultrasonic Thickness Testing Services in Boksburg
Precision wall thickness measurement to track corrosion, erosion, and remaining asset life. Performed on operational equipment without shutdown.
What Is Ultrasonic Thickness Testing?
Asset degradation is inevitable, but failure is preventable. Ultrasonic Thickness Testing is a specialized branch of our Non-Destructive Testing NDT Boksburg capabilities designed specifically to measure the remaining wall thickness of operational infrastructure — from pipelines and storage tanks to pressure vessels and heat exchangers.
How Thickness Measurement Works
Using high-frequency ultrasonic pulses (typically 5 MHz dual-element probes), our digital thickness gauges measure the exact distance between the outer and inner walls of a component with 0.1mm resolution. This allows us to accurately track material loss caused by:
- Flow-accelerated corrosion in active piping systems
- Chemical pitting in storage tanks and process vessels
- Mechanical erosion at pipe elbows, T-junctions, and reducers
- General atmospheric corrosion on structural steelwork
Keeping Gauteng Plants Operational
The critical advantage of thickness testing is that it can be performed while the plant remains online — no shutdown required. FlawTech heavily utilizes thickness testing for:
- High-Pressure Piping Inspection — corrosion mapping on active pipelines
- Pressure Vessel wall thickness surveys
- Chemical storage tank floor and shell scanning
- Remaining life calculations for insurance and regulatory compliance
Applicable Standards
- ASME Section V — Nondestructive Examination
- API 510 — Pressure Vessel Inspection Code
- API 570 — Piping Inspection Code
- API 653 — Tank Inspection, Repair, Alteration, and Reconstruction
Frequently Asked Questions
Can you measure thickness through paint or coatings?
Yes. Our instruments can measure through most paint coatings up to 0.5mm thick. For thicker coatings, we may need to prepare small test spots.
How do you report thickness data?
We provide detailed grid mapping reports showing thickness readings at predetermined inspection points, with colour-coded charts highlighting areas of concern against minimum design thickness.
How often should thickness testing be performed?
Frequency depends on corrosion rate and operating conditions. Typical intervals are 1-3 years for active piping and annually for high-risk vessels. We can calculate recommended intervals based on measured corrosion rates.
