What We Do header

Oil & Gas

Ensuring the material integrity of components in the refinery industry can be accomplished with periodic Non-Destructive Examinations. Properly schedule repairs and replacements to your assets to avoid expensive unplanned downtime and lost production.

Subtle flaws and failure mechanisms can be inspected with a high Probability of Detection (POD) and accurate and repeatable flaw sizing. At Focus NDT, ultrasonic techniques such as Phased Array Ultrasonic, TOFD (Time-of-Flight Diffractions) and Automated Ultrasonic Testing (AUT) are used to meet this demand.

Examination and Evaluation for the Refinery Industry:

  • Advanced Ultrasonic Techniques such as Phased Array Ultrasonic Inspection, Time-of-Flight Defraction (TOFD) and Automated Ultrasonic Testing (AUT)
  • Radiography (RT)
  • Magnetic Particle Inspection (MPI)
  • Liquid Penetrant Inspection (LPI)
  • Visual Inspection (API/CWB)
  • Risk Based Inspection Planning
  • Rope Access Inspection
  • Fitness for Service
  • Eddy Current

Some Critical NDT Assessments in the Refinery Industry Are:

  • TOFD/PAUT on Hydrocracker Reactors to detect and monitor cracks (flaws detectable at initial stages)
  •  Shear Wave UT & Phased Array on Pressure Vessels for the identification of fatigue cracks in vertical and circumferential weld seams as well as skirt to shell welds.

Automated Ultrasonic Testing (AUT) Techniques are  Superior at Detecting:

  • General Erosion
  • ID Corrosion
  • Welding Flaws – Non-Planer
  • Cracking/LOF
  • Hydrogen Surface Cracking – Connected
  • Hydrogen Blistering – Embedded
  • Creep Damage – Embedded
  • High Temperature Hydrogen Attack

AUT techniques experience limitations with surface related flaws. However, most surface breaking flaws can be adequately assessed with Magnetic Particle Testing (MT) or Liquid Penetrant Testing (PT), two uncomplicated and reliable methodologies.

With the versatility, sensitivity and reliability of Non-destructive Testing, rigorous trending data can be acquired for Remaining Life Evaluation and Risk Based Assessment programs.

Automated Corrosion Mapping (Ambient and Elevated Temperatures)

Corrosion Mapping is a unique, non-intrusive technique, which maps material flaws and thickness. Reaching scan speeds of up to 40″/second, our scanner can scan on diameters as small as 3 inches and lengths as long as 24 inches.

Raised Face (RF) and Ring Type Joint (RTJ) Flanges

Our scanner is able to detect the presence of corrosion on the raised face of either one or both connected flanges without the need to remove the bolts or take apart the flanges.
