Non-destructive testing

Control of the latest generation of products with Acoustic Pulse Reflectometry for each type of heat exchanger, condenser, and refrigerant, on every type of piping and other materials.

Advantages

  • quick and versatile inspection (less than 10 seconds per pipe)
  • location of leaks, obstructions, pitting, and erosion
  • checks of every type of piping and materials
  • checks of U-shapped, fined, spiral, and coiled tubing of any type
  • creation and location of defects on two- and three-dimensional models
  • digital data registration; all records are available for future examinations or comparisons
  • comparison of signals with video-endoscopic images
  • precise, detailed reports

 

Pulse reflectometry works by detecting the echoes generated by a one-dimensional acoustic wave travelling along the tube; any irregularities along the inner surface (section variations) generate a reflex.

Each type of defect – corrosion, partial or total obstruction, through holes – generate a different type of wave allowing for the identification and positioning thereof

The final result is a two- or three-dimensional diagram that makes it possible to identify the particular problem areas, such as openings corresponding to ammonia leakage or excessive vibration.

Inspections can be supported using video-endoscopy designed to confirm the nature and extent of the information provided by the instrument, carried out by one of our CND VT Level II EN473 and SNT-TC1A:2006 certified technician inspectors.
