Advanced NDE/NDT Methods


Advanced Nondestructive Examination (NDE) describes a process in which materials or equipment can be examined for various types of discontinuities, such as cracks, corrosion, or wear that does not require the destruction of the component being tested. Compared to more conventional methods these tend to use more advanced equipment and complex processes.

AUT covers a wide range of ultrasonic examination techniques which use powered mechanical scanners to locate flaws and corrosion.
Computed Radiography exists as an alternative to conventional radiography. The image capturing process is similar to conventional radiography in most ways with a few key differences.
Corrosion Mapping is a non-invasive, nondestructive ultrasonic testing technique which is used to map out variations in metal thickness which can be viewed as color images.
Digital radiography can be used to determine early signs of metal loss and points of weakness in insulated and uninsulated piping systems, pipelines, valves, among other types of equipment.
Eddy Current Testing is a NDE technique that is used in the detection of damage or corrosion in non-ferrous materials using a process known as electromagnetic induction.
Hi-Tech Testing’s IRIS Ultima is a semi-automated ultrasonic technique for the examination of both ferrous and non-ferrous tubing for isolated pitting, corrosion, and gradual wall loss.
MFL is a NDE technique where electromagnetic energy is applied to equipment in order to detect flaws.
GENISYS is the latest technology for the inspection of boiler tubes for near drum corrosion. This system is often used as a complement to Hi-Tech Testing Service’s typical boiler inspection program.
Phased Array UT is an ultrasonic nondestructive testing technique that uses multiple ultrasonic beams to inspect welds, piping, pressure vessels, clad material, storage tanks, and structural steel.
The primary use of RFT is to inspect ferromagnetic tubing, including some ferritic stainless steels. The process can detect and size wall loss at baffle locations, isolated pitting, corrosion, cracks, and mechanical damage.
Tank or Shell Crawlers are robots which are capable of performing a tank shell and floor inspection to determine the minimum floor thickness and identify plate defects.
Time of Flight Diffraction (TOFD) is an ultrasonic NDE method used to examine welds, along with the heat affected zones in piping, pressure vessels, storage tanks, and structural steel.
