Non Destructive Testing and Inspection Services

Non Destructive Evaluation International (NDEI) has been providing testing and inspection services to our customers for over 25 years. NDEI works to ensure regulatory compliance and to assist in the development and implementation of our customers’ preventative/predictive maintenance programs. Our customers include several Fortune 500 companies in the Chemical Process, Pharmaceutical, Petrochemical, and Pulp & Paper industries. NDEI offers testing and inspection services on both metal and composite equipment: tanks, vessels, and piping systems. For our Composites Division Services, please see our Levels of Service page. Our NDT methods include the following:

Traditional Non Destructive Testing:

*Ultrasonics *Pit Gauging
*Visual Inspections *Dye Penetrant
*Magnetic Particle *Barcol Hardness

Advanced Testing Techniques:

*Acoustic Emission (MONPAC Certified)
*API 653 / API 510 Services
*Remote Crawler Ultrasonics
*Robotic Visual Inspections (Photography)
*Concrete Radar and Hardness Testing

All NDEI Technicians are SNT TC-1 A Certified in the appropriate test methods and have several years experience in the application of the methods to arrive at practical solutions. In addition to the above inspection methods, each technician is certified in Confined Space Entry (CSE), First Aid, and CPR.

Acoustic Emission Testing is applicable to both Composite and Metal Tanks/Vessels. Despite its name, AE has nothing to do with sound. Instead, the test finds defects by monitoring elastic strain waves induced in the tank/vessel by placing it under load. The technique is ideal not only for aging tanks and piping, but also for verifying the integrity of repairs, and for checking on new vessels either at the manufacturer’s facility or after the tank/vessel has arrived to its final destination.

Ultrasonic Testing is used for the detection of internal and surface defects in sound conducting materials. Ultrasonic Thickness Testing permits quick and reliable measurement of thickness without requiring access to both sides of an object, tank or piping system. A pulse-echo ultrasonic thickness gauge determines the thickness of a sample or structure by measuring the time required for a short ultrasonic pulse, generated by the transducer, to travel through the thickness of the material being tested, reflect off the back surface and return to the transducer. The time is then measured and divided by two to account for the signal to and back, and then multiplied by the velocity of sound in the test material. Ultrasonic Testing can be conducted either Manually or via Remote Magnetic Crawler.

Safety is our number one concern at NDEI. All technicians have received initial and continuing safety training both in-house and through outside providers. NDEI utilizes the Association of Reciprocal Safety Councils, Inc. (ARSC). ARSC is made up of twenty-one other nationwide ARSC affiliated safety councils and maintains a reciprocal agreement among its’ affiliated safety councils.

Following is a list of Basic Orientation-Plus Topics covered:

*General Employee Safety
*Hazard Communication and Chemical Safety
*Personal Protection Equipment
*Respiratory Protection
