We are proud to be associated with Arise Global who is competent in an advanced and innovative tool in the field of Non-Destructive Testing that uses Acoustic Waves to evaluate the integrity of tubes in heat exchangers, boilers, chillers, reactors etc.

What is APR?

Acoustic Pulse Reflectometry is a technology dealing with propagation of specially designed acoustic waves in tubes. Changes in the tube cross-section generate reflections. Identifying and analyzing those reflections enable monitoring of the tube integrity. This analysis is based on the fact that every defect has its unique signature. This is schematically shown below along with a schematic of reflection signatures of typical flaws such as holes/leakages.

Typical Applications

The APR Technology can provide inspection services to industries that have heat exchangers, boilers, chillers, reactors. Some of them are:

Our technicians, with the help of a computerized inspection system and an-advanced software are able to detect internal tube flaws such as holes/leakages, blockages, erosions and pitting with a great deal of precision and speed(Less than 10 seconds per tube!). Monitoring your tubes condition will help you increase your productivity and efficiency.

Why APR?

	Fast: 10-20 times faster than any other inspection technology. Acoustic Pulse Reflectometry is a technology dealing with propagation of specially designed acoustic waves in tubes. Changes in the tube cross-section generate reflections. Identifying and analyzing those reflections enable monitoring of the tube integrity. This analysis is based on the fact that every defect has its unique signature. This is schematically shown below along with a schematic of reflection signatures of typical flaws such as holes/leakages.
	Able to inspect complex tube formation: u-tubes, u-tube bends, fin fans, y & t joints. The main challenge faced by current NDT techniques is the physical probe being stuck in u bends, t joints of complex tube geometries. But, APR inspection is effective in these scenarios as sound waves are used as virtual.
	Tubes of any material can be inspected: ferromagnetic and non-ferromagnetic materials. Current NDT techniques like Eddy Current Testing, RFT can be carried out for specific materials with specific properties. APR can inspect tubes of any material like plastic, graphite because the system makes use of sound waves as a probe.
