Precision Measurement for Critical Flow Control Equipment

Ultrasonic Thickness (UT) Testing is one of the most important tools in maintaining the safety and reliability of flow control systems used in the oil and gas industry.
At NorthStar Technologies – Oil & Gas Division, we perform API-Q2 certified ultrasonic testing to measure the internal wall thickness of components, identify material loss, and detect corrosion or erosion before it leads to equipment failure.

Our advanced UT technology allows for accurate, repeatable measurements on pipes, valves, manifolds, fittings, and other pressure-rated components — ensuring your iron operates safely under demanding field conditions.

The Purpose of UT Testing

Every piece of flow iron in service is subjected to constant pressure, temperature fluctuation, and abrasive materials. Over time, these factors lead to internal wear that cannot be seen externally.
UT testing provides a non-destructive, precise method to quantify remaining wall thickness, helping operators:

• Identify thinning or pitting before rupture occurs
• Plan proactive maintenance or replacement
• Comply with OEM and regulatory safety standards
• Extend the service life of expensive components

At NorthStar, our technicians are trained and certified in Level II and Level III ultrasonic testing, ensuring accuracy and consistency with every reading.

Our Process

Every UT inspection is performed under NorthStar Technologies’ API-Q2 Certified Quality Management System, ensuring full traceability, repeatability, and documentation.

Step 1: Preparation
All surfaces are cleaned to remove debris, coatings, or contaminants that could interfere with ultrasonic signals.

Step 2: Calibration
Test instruments are calibrated against certified reference standards to ensure precision.

Step 3: Inspection
Technicians apply ultrasonic probes to key contact points across the component. Readings are recorded digitally and cross-referenced with OEM wall-thickness requirements.

Step 4: Evaluation and Reporting
Results are analyzed and documented in our digital system, with corrosion profiles, thickness maps, and pass/fail evaluations included in your certification report.

Step 5: Certification
Each component receives a unique identifier and test record in accordance with API-Q2 documentation standards.

Applications

UT testing is essential for a wide variety of equipment and materials, including:

• Flow iron and pressure pumping lines
• Manifold assemblies and fittings
• Valves and flanged connections
• Adapters and high-pressure tees
• Vessels, piping, and pressure boundaries

Benefits of Ultrasonic Testing

• Early Detection of Defects – Identify corrosion, thinning, and fatigue before failure occurs.
• Non-Destructive Method – No cutting, sectioning, or material removal required.
• Accurate & Repeatable – Calibrated results recorded with precision and consistency.
• Compliance & Documentation – Fully traceable testing under API-Q2 procedures.
• Extended Equipment Life – Enable maintenance scheduling before costly replacement.
