Short name of company SINTES is an abbreviation of the full name of company - Structural Integrity Services. The history of new ultrasonic technologies for structural integrity improvement UIT/UP and UM goes back to 70-s and 80-s of last century. Dr.Yuri Kudryavtsev who
is one of the inventors of these technologies joined the group working on the development and industrial application of a number of
ultrasonic technologies in 1977 after
graduation from the university.
One of these technologies is based
on using high power ultrasound and aimed at fatigue improvement of parts and
welded elements - Ultrasonic Impact Treatment (UIT). The UIT is also known in
most industrial applications as Ultrasonic Peening (UP). Many companies around
the world explore the advantages and high (highest) efficiency in fatigue life
improvement achieved by using our UIT/UP technology and equipment.
The second line of
products/services is the ultrasonic technique and equipment for non-destructive
residual and applied stress measurements. In many applications, including the
welded elements and structures, this ultrasonic measurement (UM) technique is
the most efficient for residual stress measurements in lab and field
conditions.
Below is a list of selected historical
