TWI technicians are certified through a variety of different ways, according to the discipline they actually are certified in. Our NDE inspectors are certified in accordance with the American Society of Non-Destructive Testing (ASNT) document TC-1A. These inspectors are trained (classroom/OJT) and tested through our ASNT-TC-1A in house program as well as in accordance with our written Quality Control Program.
Certified Weld Inspector (CWI): An American Welding Society Certification by examination, ensures thorough knowledge in every facet of weld inspections.
Visual Inspection: Determines the general mechanical and structural condition of components and supports. Verifies clearances, settings, physical displacements, loss of integrity at bolted or welded connections, leakage from pressure retaining components, loose or missing parts, corrosion, erosion and cracking.
Ultrasonic Inspections: Ultrasonic flaw detectors used to inspect piping, vessels and field welds for discontinuities. Ultrasonic thickness measurement units check material thickness and verify material loss due to corrosion or erosion.
Visible and Fluorescent Dye Penetrant Inspections: Uses fluorescent and visible dye penetrants for locating discontinuities open to the surface in the component being inspected.
X-ray and Gamma Radiographic Inspections: Uses gamma and x-ray sources to perform a volumetric examination of a weld or metal.
Portable Magnetic Particle Inspection: Outstanding choice when inspecting ferrous materials. Conducts inspections using AC/DC yokes, prods/clamps, cable wraps and central bar conductor (CBC).
Borescope Inspection: Utilizes a small fiber optic cable and video screen to perform a visual inspection inside small diameter pipes and tubes.
Hardness Testing: Verifies the material hardness of a given metal.
Cladding Thickness Assessment: Used to measure coatings and clad metals.
Ultrapipe Licensed Software: Software used to monitor, calculate and schedule inspection frequencies. Establishes equipment reliability in accordance with established PSM Process Safety Management procedures.
AutoCAD: Software used to draw isometric drawings of vessels, tanks and piping systems.
Infrared Imaging: State of the art equipment to locate, detect hot zones or thermal gradient changes to various equipment items.
