HMI utilizes RT to detect discontinuities in ferrous and non-ferrous materials. Applying the proper procedures and code requirements allows HMI to determine the acceptability and quality of welds on pressure vessels, piping, storage tanks, and other materials.

UT uses high frequency ultrasonic waves to detect imperfections, measure material thickness, and determine acceptance or rejection of a test object based on a referencing code or standard. Techniques used at HMI provide instant results and are sensitive to both surface and subsurface discontinuities throughout the material.

- Ultrasonic Thickness Testing (UTT)

High Mountain’s UTT can measure wall thickness on piping, pressure vessels, storage tanks, beams, and other materials.

-Shear Wave UT (A-Scan)

Shear Wave or A-Scan testing can transmit an ultrasonic wave at a predetermined angle into the test material. These angle beams are used to determine the quality of a material based on accepted standards and procedures.

-Corrosion Scanning

Using Phased Array technology HMI can locate and verify internal defects such as corrosion, pitting, and laminations. Size and position of the defect can be determined using multiple scans simultaneously providing information on the integrity and quality of your materials.



HMI uses this technique, creating a magnetic field, to detect surface and near surface discontinuities such as cracks, seams, and laps. This technique can distinguish the size, shape, location, and extent of a discontinuity.



This technique is employed by HMI to exploit defects open to the surface in multiple types of non-porous materials. This process is great for finding cracks, leaks, and fatigued defects on in-service components.



Visual Inspection is used for insuring the weld, structure or other components meet the applicable specification or standard provided. HMI's Certified Welding Inspectors (CWI) can provide onsite visual inspection as well as monitor and evaluate welder qualifications.



3D Laser Corrosion Mapping is a new and very acurrate technology. This type of inspection gives you the ability to aquire a full 360 degree area of the asset in need of (ILI) verification. The program allows measurement of depth and the ability of installing interaction perameters to give you the most precise information required.
