Specialized ANDT Services
At GULF QUALITY CONTROL CO. Ltd (GQCCO), we proudly offer a wide range of Specialized Advanced Non-Destructive Testing (ANDT) services tailored to meet the high-accuracy inspection needs of today’s industrial sectors. These services go beyond conventional NDT, providing deeper insight, detailed imaging, and more reliable flaw detection across critical equipment and components.
We provide the following Specialized ANDT services with the support of highly qualified technicians and the latest inspection technologies:
Phased Array UT Inspection (PAUT)
We provide Phased Array Ultrasonic Testing for high-resolution weld inspection, corrosion mapping, and flaw sizing. PAUT allows us to scan complex geometries with speed and accuracy, making it ideal for critical applications in pipelines, pressure vessels, and structural welds.
This service is commonly used during fabrication, shutdowns, and in-service evaluations where precision and speed are both required.
TOFD UT Inspection (Time of Flight Diffraction)
Our TOFD inspection services are offered for precise detection and sizing of internal defects in weld joints and pressure-retaining components. We use TOFD during pre-service weld quality verification and periodic in-service inspections where accurate depth sizing of flaws is essential.
It is a reliable and efficient alternative to traditional radiographic testing, especially in areas where radiation safety is a concern.
IRIS Tube Inspection (Internal Rotary Inspection System)
We deliver IRIS inspection services for the exact wall thickness measurement of tubes. This method provides a clear picture of corrosion, erosion, and pitting inside tubes, helping our clients take proactive maintenance decisions.
Our IRIS systems are calibrated, portable, and suitable for both ferrous and non-ferrous materials.
ET & RFET Tube Inspection
We provide Eddy Current Testing (ET) and Remote Field Eddy Current Testing (RFET) for non-invasive inspection of heat exchanger tubes.
These services allow for fast and accurate detection of ID/OD corrosion, cracks, wear, and thinning, especially useful during shutdowns or preventive maintenance programs.
MFL – Tank Floor Inspection (Magnetic Flux Leakage)
Our MFL inspection service is ideal for inspecting the floor plates of aboveground storage tanks (ASTs) without removing coatings or requiring surface preparation. We use high-sensitivity scanners to detect and map corrosion, pitting, and wall loss in carbon steel tank bottoms.
This service supports asset integrity management by giving owners a reliable view of tank condition before costly repairs or replacements.
Eddy Current Inspection (Surface & Subsurface)
We also offer eddy current inspections for surface and near-surface flaw detection in conductive materials. This method is highly sensitive to small cracks, especially around fastener holes, welds, and critical stress areas.
It is widely used in aerospace, fabrication, and power plant components to ensure the integrity of metallic structures with minimal surface preparation.
