We utilize a wide variety of Nondestructive Testing (NDT) and quality procedures in accordance with ASME Section V. With experience in all of these procedures and others, we are able to provide comprehensive services to our customers and meet their specifications and documentation requirements.
Digital Radiography (DR-RT)
We utilize digital X-ray sensors, instead of traditional photographic film, to examine the quality of welds and other procedures. This offers:
- immediate image preview and availability
- time efficiency and cost reduction by avoiding chemical processing
- the ability to digitally transfer and enhance images with a wider dynamic range
Computed Radiography (CR-RT)
This process utilizes an imaging plate (IP) made of photostimulable phosphor, again avoiding an exposure process. The resulting digital image can be viewed and enhanced using software to adjust contrast, brightness, filtration and zoom.
This technology allows for a mobile, real-time x-ray, enabling inspection in the field and on large-scale projects.
Liquid Dye Penetrant Testing (PT)
This is a cost efficient inspection method for locating surface-breaking defects in all non-porous materials, including in casted, forged and welded surfaces. It can be used to inspect for hairline cracks, surface porosity or leaks on new equipment or fatigue cracks on existing equipment.
The process includes:
- Application of the penetrant
- Removal of excess penetrant
- Application of the developer
Magnetic Particle Testing (MT)
Also known as Mag Particle Testing, this process detects surface and subsurface discontinuities of metals, including iron, nickel and cobalt alloys. Using a magnetic field, objects can be tested to identify an area of potential leakage.
Ultrasonic Testing – Thickness (UT)
This family of non-destructive testing (NDT) techniques utilize ultrasonic waves. In most applications, a short pulse wave is transmitted into the material to detect internal flaws or characterize a material. We utilize ultrasonic thickness measurement to monitor metal thickness and weld quality.
Visual Testing (VT)
Inspection using the raw human senses, such as vision, hearing, touch and smell and/or any non-specialized inspection equipment.
Helium Leak Detection (LT)
Utilizing pressurized helium (the lightest inert gas) as a tracer gas, we can detect leaks in concentrations as small as one part in 10 million.
Positive Material Identification (PMI)
This group of tests offers an analysis of a metal alloy composition with a percentage of represented elements. We perform PMI using X-ray fluorescence (XRF) or optical emission spectrometry (OES).
The amount of ferrite present in duplex stainless steel can provide its FN or Ferrite Number. We utilize Ferrite testing to ensure our end products meet customers’ specfications for the FN range, maximizing corrosion resistance.
Boroscopic Visual Inspection
This visual inspection technique commonly used in internal heat exchangers and tubes utilizes fiber optic and rigid boroscopes and usually photography or videotape to reveal internal defects.
