Using Dry Ice Blasting to Clean prior to Non-Destructive Testing (NDT)

Posted by impactindustrial on Sep 18, 2017

The value of using Dry Ice Blasting to remove contaminants prior to Non-Destructive Testing (NDT) is unparalleled. By introducing recycled CO₂ as a blast media in the form of dry ice pellets into a pressurized air-stream, you get a non-abrasive cleaning solution that allows equipment to be cleaned without dismantling or relocating. Dry ice is a gentle media, so it will not damage sensitive equipment and it exceeds the speed and effectiveness of any other cleaning solution, therefore increasing production rates, reducing equipment downtime, and enhancing project and equipment efficiency.

Dry Ice Blasting removes grease, oil, tar, paint, etc. and promotes better non-destructive testing (NDT) results including magnetic particle inspections (MPI).

Non-Destructive Testing (NDT) is a wide group of analysis techniques used to test and evaluate the properties of a material, component, or system without causing damage. These tests are routinely used on things such as boilers, vessels, piping, building materials, fabrication and joining processes to evaluate the integrity of welds, and welded structures.

For example, welds may be tested using NDT techniques such as industrial radiology or industrial CT scanning using X-rays or gamma rays, ultrasonic testing, liquid penetrant testing, eddy current or magnetic particle inspection (MPI).

Magnetic Particle Inspection (MPI) is a non-destructive testing process used to detect surface and slightly subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys. The process puts a magnetic field into the part.

Benefits of Dry Ice Blasting prior to Non-Destructive Testing

Dry ice cleaning is safer and more environmentally friendly choice when compared to traditional techniques such as abrasive blasting and pressure washing. The dry ice returns to a gas upon impact, making dry ice cleaning a dry process. This helps minimize cleanup time, reduces disposal costs, and eliminates secondary waste.

Examples of customers requiring Dry Ice Cleaning prior to Non-destructive testing (NDT) would be:

  • Lifting and hoisting equipment owners
  • Pipe/pipeline
  • Petroleum refineries
  • Chemical processing and production facilities
  • Mines
  • Power generation plants
  • Storage tanks and associated facilities

If your looking for an environmentally friendly cleaning process with an amazing upside, then you need to consider Dry Ice Blasting as your preferred cleaning method when preparing for your next routine non-destructive test or inspection.
