Radiography testing is one of the most sophisticated but among the most accurate and hence reliable method of flaw detection in materials. The records of examinations can also be permanently maintained for future retrieval and reference unlike in other testing methods like Magnetic Particles Testing and Dye Penetrant Testing that rely entirely on testing technician’s interpretation of results. A permanent image of radiographic examination is produced on a radiation-sensitive paper known as a radiography film.
Radiography and ultrasonic test are the two methods which are generally used for successful detection of internal flaws that are located deep below the surface of materials. In welding, Radiography Testing is used to detect flaws like cracks, lack of fusion, inadequate root penetration, undercuts, porosity and any other voids and inclusions.
At Quality Experts Limited, we utilise conventional, digital and computed radiography using both gamma ray (γ) and X-ray radiation sources to meet our varied client needs. Our radiography technicians with their vast experience are highly trained and are always bent to strict adherence to international QHSE standards as well as company laid down safety procedures when executing this specialised inspection test.

Magnetic Flux Leakage (MFL) is one of the most advanced Nondestructive testing methods used in integrity assessment of storage tanks and pipelines. It requires highly skilled manpower and sophisticated equipment.
MFL is used in corrosion mapping (detection of corrosion) in tank bottoms and roof tops in storage tanks and pitting in tanks and pipelines. The basic operation principle is using Eddy current sensors integrated in the magnetic flux sensors to detect metal loss defects (such as corrosion) in a steel structure. At Quality Experts Limited, we have heavily invested in latest technology equipment and personnel to give our clients the best service.
At Quality Experts Limited, we help our clients to identify fabrication deficiencies on their new installations and usage defects due to wear and tear in in-service equipment. By partnering with us, we add quality to your business by significantly reducing potential downtimes and/or complete shut downs and avert possible losses due to product quality compromise orinstallations failure.
