Magnetic Flux Leakage (MFL)

Magnetic Flux Leakage (MFL)

The larger the corrosion area the larger the field will be. The storage of dangerous goods in tanks must be done in a safe way. In order to reduce the economic as well as the environmental risks to a minimum, a thorough knowledge of the condition of the tank, and in particular the tank floor, is of outstanding importance.

To minimize inspection time we offer a quick and above all reliable inspection, by combining two techniques: Magnetic Flux Leakage (MFL) and Ultrasonic Testing (UT). By using these two techniques, corrosion can be effectively detected (MFL) and reliable quantified (UT).

Pulsed Eddy-Current (PEC)

Pulsed Eddy-Current (PEC)

Compared with conventional eddy current testing , during a PEC inspection there is no need for direct contact with the object being tested. Measurements can be made through coatings, insulation materials, weather sheeting and even corrosion products. This means that inspections can be carried out through any material that does not conduct electricity. It is a very useful characteristic that also enables high temperature testing or offshore well inspections. This also makes PEC very suitable for inspections where the surface of an object is not accessible.

Acoustic Emission

Acoustic Emission

If you need to detect flaws in metallic pressure equipment , acoustic emission testing is one of the most reliable ways to detect the early stages of stress corrosion cracking. When a material undergoes stress or a series of internal changes such as corrosion, it generates energy from localized sources which produces sound waves. Acoustic emission testing is a non-destructive testing method designed to monitor sound waves emitted during material stress or failure. This condition monitoring method enables inspectors to examine metal deformation under stress and detect the sound of cracks and failures growing within the material.

Unlike other non-destructive testing methods, AE testing does not send energy into the inspected pressure vessel, but rather detects the energy emitted by the equipment itself. This technique is therefore time-effective because it can be performed during material operation. Acoustic emission testing enables you to monitor and inspect your entire pressure equipment, from tanks to welds. It provides immediate results and early warning of possible damage or failure in pressure equipment as well as solutions to determine the appropriate pressure level.

Guided Wave

Guided Wave

Guided Wave, is an advanced corrosion inspection technology that uses low frequency guided ultrasound waves travelling along the pipe, providing 100% coverage of the pipe length. Effected areas are precisely located in terms of distance from the transducer ring and highlighted for further local examination by visual or other conventional NDT methods. This nondestructive screening technique can be used without extensive scaffolding and minimizes the requirement of removing insulation along the piping.

Time of Flight Diffraction (TOFD)

Time of Flight Diffraction (TOFD)

Welding defects can compromise the stability and integrity of a welded structure. When you need confidence in testing of welds, Time of Flight Diffraction (TOFD), a high performance non-destructive testing (NDT) technique offers you accurate detection of cracks, slag and lack of fusion.

UT Phased Array (PA)

UT Phased Array (PA)

Phased array is widely used in several sectors, from power generation to construction industries. It is an advanced non-destructive testing (NDT) method that uses an ultrasonic technique to determine component quality and detect failure such as flaws or cracks. Furthermore, Phased Array Ultrasonic Testing can be effectively used for wall thickness measurements in conjunction with corrosion testing. Its efficiency comes from the combination of many angles and focus depths through to one probe which then performs several different inspections without the need for changing the transducer assembly. The inspection results are clearly stored and displayed for reporting. It can be used on standard and special materials like austenitic and high alloy materials.
