Non-Destructive Testing (NDT) inspections are an integral part of the Oil & Gas and petrochemical industries. These inspections are crucial for ensuring the safety, reliability, and longevity of components and systems. We offer comprehensive non-destructive testing and materials testing services across various industries to detect defects in components, thereby reducing the risk of failure and enhancing reliability. Our experienced operators are qualified and certified to Level 2 and Level 3 standards in accordance with ISO 9712 and SNT TC 1A, ensuring the highest quality and accuracy in testing procedures.
The NDT services we provide include:
Magnetic Particle Inspection (MT)
MT is used to detect surface and near-surface discontinuities in ferromagnetic materials. This method involves the application of a magnetic field to the material and the use of ferrous particles to highlight flaws, such as cracks or inclusions.
Visual Testing (VT)
Visual Testing is the most basic and commonly used NDT method. It involves the direct inspection of a component with the naked eye or using tools such as magnifying glasses, borescopes, and cameras to identify surface defects and irregularities.
Dye Penetrant Inspection (PT)
PT is employed to detect surface-breaking defects in non-porous materials. The process includes applying a visible or fluorescent dye to the surface, allowing it to penetrate flaws, and then removing the excess dye. A developer is then applied, making the defects visible under ultraviolet or white light.
Eddy Current Testing (EC)
EC is used to detect surface and near-surface defects in conductive materials. It involves inducing electrical currents (eddy currents) in the material and monitoring changes in the current flow, which indicate the presence of defects.
Alternating Current Field Measurement (ACFM)
ACFM is a technique for detecting and sizing surface-breaking cracks in metallic structures. Unlike MPI, it does not require direct contact with the surface and can be used through coatings and at elevated temperatures, making it ideal for in-service inspections.
Positive Material Identification (PMI)
PMI is used to verify the chemical composition of materials. This method ensures that the correct materials are used in the manufacturing process, preventing potential failures due to material mix-ups. Techniques like X-ray fluorescence (XRF) and optical emission spectrometry (OES) are commonly employed in PMI.
Thermography (TT)
Thermography involves the use of infrared cameras to detect temperature variations on the surface of a component. These variations can indicate underlying defects, such as delaminations, voids, or cracks. This method is non-contact and can be used to inspect large areas quickly.
By employing these advanced NDT techniques, we help ensure the integrity and performance of critical components and systems across a wide range of industries.
