Nondestructive Testing (NDT)

Gamma Ray (RT) Radiography Testing

TechCorr's X-Ray capabilities range from 4 MEV units utilized to radiograph extremely large and thick castings and forgings, to portable X-Ray cameras used for field weld applications and thin wall material inspection.

TechCorr supplies a complete line of radiographic services for both shop and field applications with over 75 mobile dark rooms throughout the United States and Latin America.

Tank Bottom Inspection

Out-of-Service Tank Inspection in accordance with API 653 requires an internal inspection every ten (10) years. TechCorr provides clients API 653 tank bottom inspections using certified technicians and advanced inspection equipment.

Ultrasonic Shear Wave

Ultrasonic Shear Wave, sometimes referred to as Angled Beam Ultrasonic testing, can be used to inspect pipe, critical welds in pressure vessels and plate weldments, and can be used to inspect cracks for depth, size, length and orientation.

ACFM Crack Detection

Alternating Current Field Measurement also referred to as ACFM is a one-pass method to inspect welds and most other meterials to locate and size surface breaking cracks. This technique replaces conventional dye penetrants and magnetic particle testing and the ultrasonics required to size defects.

Infrared inspection

Infrared inspection is a vital tool when performing predictive and preventative inspection and maintenance on electrical equipment, mechanical equipment, process equipment, rotating equipment and structural systems. TechCorr deploys certified infrared engineers and technicians to client sites to perform infrared inspection using a combination of high resolution infrared imaging devices, conventional video, still photography and infrared inspection industry best practices

Pipeline X-Ray Crawlers

The X-Ray Crawler is similar to conventional radiography however an x-ray source tube on a crawler device is run inside the pipe to each weld. The technique is quick and can inspect on average 150 welds per day. The biggest advantage of x-ray crawlers is their speed.

Digital Radiography

Digital Radiography is one of the newest forms of radiographic imaging. Captured images can be digitally enhanced for increased detail and are easily archived. TechCorr employs a wide array of digital radiographic systems to solve specific industrial problems.

Pulsed Eddy Current-Testing

Pulsed Eddy Current is a unique corrosion survey method that allows ferrous objects to be surveyed without the need to make contact with the surface (in contract with ultrasonics). This means that measurements can be performed on objects covered with insulation, asbestos, fireproofing, concrete or coating. The high costs for removal of insulation can therefore be avoided. At the same time scaffolding can be reduced by using rope access or by mounting the measurement sensor on an extension pole or robotic crawler.

Short Range Guided Wave Ultrasonic Technique (SRGUT)

The Short Range Guided Wave Ultrasonic Technique (SRGUT) was designed to test the annular plate of above ground storage tanks (AST's) while the tank remains inservice. The technique is based on the concept of pulsing guided laminar waves into the base material from the chime area. The waves propagate up to three feet into the annular plate. When corrosion, pitting, erosion are present the ultrasonic waves mode convert and are received by the same transducer.
