We offer both field inspection services and lab inspection services. If you project can not be move to our facility we have the processing capabilities to perform our testing in the field, at your location, or perhaps your vendor or customers site.

Radiography
Radiography involves the use of penetrating X or gamma radiation to examine parts and products for imperfections. An x—ray machine or radioactive isotope is used as a source of radiation. Radiation is directed through a part and onto film. When the film is developed, a shadowgraph is obtained that shows the internal soundness of a part. Possible imperfections show up as density changes in the film, in much the same manner as an x—ray can show broken bones.

Digital Radiography
We are not talking about just using a special plate to take X-rays instead of film but to be able to get ultrasonic type information, from an X-ray, to get layer by layer information about a part, to be able to reverse prototype a product from and item to a drawing. To be able to dimensional check a part like no other type of information collector.

Ultrasonics
Ultrasonic testing uses the transmission of high frequency sound waves into a material to detect imperfections within the material or changes in material properties. The most commonly used ultrasonic testing technique is pulse echo wherein sound is introduced into the test object and reflections (echos) are returned to a receiver from internal imperfections or from geometrical surfaces of the part.

Liquid Penentrant
Liquid Penetrant testing is probably the most widely used NDT method. The test object or material is coated with a visible or fluorescent dye solution. The excess dye is removed from the surface, and then a developer is applied. The developer acts like a blotter and draws penetrant out of imperfections which open to the surface. With visible dyes, the vivid color contrast between the penetrant and the developer makes the "bleedout" easy to see. With fluorescent dyes, an ultraviolet lamp is used to make the "bleedout" fluoresce brightly, thus allowing the imperfection to be seen readily.

Magnetic Particle
Magnetic particle testing is done by inducing a magnetic field in a ferro—magnetic material and dusting the surface with iron particles(either dry or suspended in a liquid). Surface imperfections will distort the magnetic field and concentrate the iron particles near imperfections, thus indicating their presence.
Magnetic Particle Testing or Magnaflux as it is sometimes called uses magnetic leakage fields to detect surface and subsurface cracks and discontinuities.

Corrosion Erosion
Erosion and corrosion of existing pipe is a very real problem in today’s power and generation plants the high cost of down time coupled with the high cost of repair could be put you company out of business. But to strip off the insulation, especially if it is asbestos, empty the line to try to X-ray it or to take hundreds of thickness readings could be equally as costly. Thru view scanning can scan a pipe wall thru insulation, thru product with out stopping your production. If you have asbestos insulation and it has already been or will be sealed and abated you do not have to remove it. We have accuracy as close as .001 ". We also can examine a full length of pipe and can show you every thin spot and with the software you can look at any area and find its true thickness

Visual Examination
Probably the oldest and most common method of NDT is visual examination, which has numerous industrial and commercial applications. Examiners follow procedures ranging from simple to very complex, some of which involve comparison of workmanship samples with production parts. Visual techniques are used with all other NDT methods.

Acoustic Emission
When a solid material is stressed, imperfections within the material emit short bursts of energy called "emissions". In much the same manner as ultrasonic testing, special receivers can detect these acoustic emissions. The source of "emissions" can be evaluated through study of their strength, rate, and location.

Eddy Current
In eddy current testing, electrical currents are generated in a conductive material by an induced magnetic field. Interruptions in the flow of the electric currents (eddy currents), which are caused by imperfections or changes in a material’s conductive properties, will cause changes in the induced magnetic field. These changes, when detected, indicate the presence of a change in the test object.
