High-Resolution Internal Rotary Inspection System (IRIS) for Tube Integrity

Qualitest Offshore Inc. provides advanced IRIS Tube Inspection services across Guyana’s offshore platforms, FPSOs, onshore fabrication yards, and industrial plants. IRIS is a powerful Non-Destructive Testing (NDT) method used for high-accuracy wall thickness measurement and defect detection in heat exchanger, boiler, and chiller tubes.

Using ultrasonic technology, our certified technicians deliver detailed internal inspection data to help detect corrosion, erosion, pitting, and wall loss. IRIS is ideal for both ferrous and non-ferrous tubes, offering exceptional clarity and reliability for critical maintenance programs.

What is IRIS Tube Inspection?

IRIS stands for Internal Rotary Inspection System. It uses a rotating ultrasonic probe inserted into water-filled tubes to scan the entire internal surface. As the probe rotates and moves through the tube, it sends and receives ultrasonic signals that generate precise cross-sectional imaging.

This technique is highly effective for measuring internal and external wall loss, making it essential for reliability-based maintenance planning.

Key Benefits of IRIS Inspection

• Extremely accurate wall thickness measurement
• Capable of detecting pitting, corrosion, and erosion
• Works on both ferrous and non-ferrous tubes
• Provides full circumferential coverage
• No radiation, safe for all environments
• Delivers digital, high-resolution inspection reports

IRIS Inspection Applications in Guyana’s Industrial Facilities

Qualitest’s IRIS services are widely used in oil & gas, power generation, petrochemical, and marine industries. Common applications include:

• Heat exchangers, chillers, and boilers in refineries and chemical plants
• FPSOs and offshore platform cooling systems
• Air coolers and fin fan tubes
• Process plant tube bundles and shell-and-tube equipment
• Onshore fabrication shops and equipment servicing units

IRIS is particularly useful during plant shutdowns, turnarounds, and condition assessments, giving clients the data needed to make informed maintenance decisions.
