Ultrasonic Testing (UT) utilizes sound waves with a frequency greater than 20 kHz (inaudible to humans) to detect flaws and/or material properties. Interpretation is comparative, based on calibrated responses from known size flaws in acoustically similar material.
Magnetic Particle Testing (MT) is a nondestructive method which utilizes the flux leakage arising as a result of near surface discontinuities to detect flaws. A magnetic current or field is imposed while the accumulation of iron powder indicates flaws.
Penetrant Testing (PT) is one of the simplest non-destructive test methods utilized for detecting surface breaking discontinuities in non-porous, non-absorbing materials. Penetrant Testing can be utilized on any non-porous, non-absorbing material, on surfaces, entire objects and complex shapes.
Radiographic Testing (RT) has been employed in several industries and for a variety of inspection types. Radiography is also a widely used volumetric-testing technique. AEIS is a time tested provider of this service in the industry.
Cutting and Welding operations can affect mechanical properties of alloy steels. Hardness of the material has a direct relationship to the tensile strength of the material. In-situ measurement of hardness provides valuable information and is evaluated by codes and specifications.
Positive Material Identification (PMI) can verify alloys, establish lost material traceability, verify filler material composition and dilution rates in welds, and confirm the integrity of process piping, valves, and reaction vessels as per ASTM E1476 and API RP578.
Phased Array Ultrasonic Testing (PAUT) offers us the ability to modify electronically the acoustic probe characteristics. Probe modifications are performed by introducing time shifts in the signals sent to (pulse) and received from (echo) individual elements of an array probe.
Eddy-current testing (ET) is an electromagnetic testing method wherein a localized alternating current loop is induced in the test object. The inductive reactance of the probe to the magnetic field of the induced current reveals subsurface flaws.
Visual examination or Visual Testing (VT) is one of the most common and most powerful means of non-destructive testing. Inspection of objects, parts, components engineering structures is the oldest and reliable non-destructive testing method.
Infrared thermography is a non-destructive technique for detecting temperature differentials that may indicate problems such as loose electrical connections or excessive friction in mechanical systems. A camera-like device views a large area, converting infrared emissions into a visual display.
Welding is one of the most significant causes of residual stresses and typically produces large tensile stresses in the weld, balanced by lower compressive residual stresses elsewhere in the component. The residual stresses in components are caused by internal strains.
Vibration monitoring allows for an accurate detection of subtle variances, allowing for predictive rather than reactive maintenance. A data-driven monitoring system continuously analyzes performance for real-time signs of anomalous movement.
API inspections for pressure vessel inspection, piping inspection, fired boilers, process heaters (furnaces) and above ground storage tanks are generally conducted pursuant to standards created by the American Petroleum Institute (API).
Corrosion mitigation is facilitated by increased awareness, improved standards, advanced life prediction and better performance management. Our Corrosion Control Group specializes in the analysis, mitigation and remediation of corrosion on all types of metal substrates and erosion of concrete substrates.
