Upstream Oil & Gas

Corrosion Cell

TesTex Inc. has a wide variety of services available to Upstream Oil Providers. We utilize a variety of Techniques:

  • Low Frequency Electromagnetic Technique
  • Ultrasonic Thickness Measurement
  • Mag particle & Dye Penetrant
  • Balanced Field Electromagnetic Technique

Low Frequency Electromagnetic Technique and Ultrasonic Thickness Measurement

Corrosion Cell
Waveform shows a corrosion cell on the shell of a tank.

Using our proprietary Low Frequency Electromagnetic Technique (LFET) we can quickly scan Tank Walls, Tank Floors, and Pipelines for potential problem areas. This allows us to quickly determine where Ultrasonic Thickness measurement needs to be done to determine areas of wall loss without the tedious preparation work needed for other techniques. For Tanks we can utilize our Falcon system for tank floor scanning, our hand scanners for tank walls, and our LineCat for scanning pipelines. All of these inspections can be done remotely utilizing three man crews and portable power sources. This allows us to deploy our work crews quickly to remote locations where these tanks and pipelines are usually situated.

Mag Particle / Dye Penetrant

Using techniques like Mag Particle and Dye Penetrant we can determine if there is an issue with weld cracking on vital points in the tank. This includes welds around manholes, plate welds, and structural add-ons like D-rings and lift points on tanks. Customers utilizing this type of inspection will receive a report with pictures to show potential problem areas, as well as a general visual inspection of the site to determine other potential issues. Additionally we have technologies like the Balanced Field Electromagnetic Technique (BFET) to help determine if cracking exists in welds. We have utilized this in the past for small welded areas like socket welds providing a much safer test than utilizing X-rays.
