Products & Services
NON-DESTRUCTIVE TESTING

Specializing in conventional ultrasonics, phased array, and magnetic particle testing

ULTRASONIC TESTING

Ultrasonic testing (UT) involves imparting high frequency sound into the test piece and studying the return echoes.  The operator evaluates the echo time and amplitude to make measurements and identify flaws. 


THICKNESS TESTING

Sound from single or dual element transducers is reflected off the backwall of the test piece. The return time of the echo is used to evaluate the thickness. Can be performed in echo-to-echo mode to negate the coating thickness in the case of painted surfaces.


SHEAR WAVE WELD INSPECTION

Uses an angled wedge to impart the sound beam at a specific angle. Commonly used in manual inspection of welds.


PHASED ARRAY

By dividing the transducer into multiple small elements fired independently, the beam can be swept through a range of angles. Commonly used to inspect welds and perform detailed corrosion mapping. Can provide an image and an encoded record of the scan.

MAGNETIC PARTICLE TESTING

A magnetic field is applied across a ferromagnetic test piece while test particles are applied. Surface or near-surface discontinuities disrupt the magnetic field and attract the particles, which build up and reveal cracks and other discontinuities invisible to the naked eye. In the field, the most common way of performing MPI is with an AC yoke. 


VISIBLE MPI

Performed under ambient lighting or with the aid of a flashlight.  Can be performed with wet solution or with dry powder, and may be performed over thin non-conductive coatings such as contrast paint to aid visibility.  Particles can be seen with the naked eye after inspection.


FLUORESCENT MPI

Special particles are used in combination with an ultraviolet (black) light and controlled ambient lighting to further enhance detection. 

NDT LEVEL 3 CONSULTING

HNEI offers NDT Level 3 services including procedure development, training, and auditing.

When you want Level 3 insight from someone who spends most of their time in the field (but not in this picture... I said "most" of the time)

PROCEDURE DEVELOPMENT

Procedure development, customized for your needs, done in full compliance with the codes and standards that your inspection needs to follow. A procedure is not just part of a paper trail - it's the instruction set for your technicians to follow to ensure a precise and complete inspection. Too often procedures are tedious, unreadable (unless you're a lawyer), and ignored. Then when questions arise, everyone scrambles to find it. This shouldn't be the case.  A good procedure should be visual, easy to follow, and concise.

TRAINING

NDT training needs to strike a balance between technicality and practicality. In the real world, it comes down to being proficient and doing the job right the first time. In ultrasonic testing, this means proper equipment selection, technique, calibration, execution and reporting. Most of all, well trained technicians are confident in their abilities.

Engineering Services

Engineering services including mechanical design and lift equipment inspection & certification

STRUCTURAL CERTIFICATION INSPECTIONS

Professional Engineering supervision, CGSB non-destructive testing, and stamped certification for annual or periodic structural inspection requirements as per provincial regulations and safety code standards such as CSA-Z150 and CSA-B354.


MECHANICAL DESIGN

NDT tool and calibration block design related to ultrasonic testing.
