Holloway Houston offers Nondestructive Testing (NDT) services for lifting and rigging equipment and its components. Our methods include Magnetic Particle Testing (MT), which finds flaws at or near the surface of ferromagnetic metals; Liquid Dye Penetrant Testing (PT), which finds flaws open to the surface; and Ultrasonic Testing (UT), which finds flaws inside the metal. None of them damages the part being inspected.
Magnetic Particle Testing (MT): Detects surface and near-surface discontinuities in ferromagnetic materials. We can identify cracks, weld defects, and other imperfections in metal components by applying magnetic fields and iron particles.
Liquid Penetrant Testing (PT): Detects surface-breaking defects in non-porous materials. By applying a liquid dye and developer, we reveal cracks, seams, and other discontinuities that could compromise the integrity of your equipment.
Ultrasonic Testing (UT): Detects internal flaws and assesses material thickness using high-frequency sound waves. TUT is widely used on welds, castings, and other components where the condition inside the metal matters as much as the surface.
On-Site Services: To minimize downtime, Holloway Houston offers on-site NDT services. Our mobile inspection units have the latest technology to provide efficient and accurate inspections at your location.
