We use a range of Non-Destructive Testing (NDT) to verify the integrity of critical components — without compromising the material or structure. These methods are essential for detecting internal and surface-level discontinuities, confirming weld bonding, and ensuring long-term reliability in harsh environments. Testing is carried out by certified inspectors, in accordance with project specifications and international standards, using calibrated equipment and fully documented procedures.
High-frequency sound waves are used to detect internal defects or bonding issues between layers, particularly in weld overlay areas. UT allows us to evaluate the quality of fusion without dismantling or cutting the part — ideal for checking internal CRA-to-substrate bonding.
An advanced form of UT, PAUT uses multiple angles and phased sensors to scan complex geometries, such as the ends and triple-point areas of Mechanically Lined Pipe (MLP). This provides high-resolution imaging for deeper analysis and documentation.
Primarily used post-expansion in MLP production, ECT detects minute cracks, liner movement, and bonding issues without contact. It's highly effective for thin-walled liners and corrosion-resistant alloys, offering immediate feedback on metallurgical integrity.
DR allows us to capture high-resolution internal images of welds, triple points, and complex assemblies. The results are instantly viewable and archivable, supporting fast decision-making and traceable reporting.
PT is routinely applied to ensure surface integrity, particularly on weld overlays and machined components where precision is critical. This technique offers fast, reliable results and is ideal for detecting flaws that may not be visible to the naked eye.
At Proclad, RT is employed to validate weld quality across a variety of materials and thicknesses, ensuring compliance with international standards. It provides a detailed view of internal discontinuities such as slag inclusions, voids, or lack of fusion, making it an essential tool in our quality assurance process.
By applying magnetic fields and iron particles to the surface, Proclad inspectors can detect cracks, seams, and other irregularities with high sensitivity. It is commonly used for weld joints, flanges, and pressure-retaining components, ensuring each part meets strict safety and reliability standards.

Every component undergoes a final visual inspection, including surface finish, bevel condition, weld integrity, and cleanliness. Key dimensions such as overall length, end prep, and critical tolerances are rechecked to confirm alignment with client specifications and applicable codes.
Where required, internal surfaces are cleaned, pickled, or passivated to remove welding residue, scale, and contaminants — especially important for CRA materials and high-spec process systems. Internal bores are inspected visually and/or with a boroscope to ensure no inclusions remain, and end caps or plugs are fitted to maintain condition during transit.
All test records, inspection logs, certificates, and material traceability reports are compiled into a comprehensive QA dossier, ready for submission or handover. Final release is granted only when all documentation is complete and quality sign-off is achieved. Our logistics team ensures items are safely packed and clearly marked for seamless delivery to site.
