Applications

This test is applicable to the following infraestructures:

Lap welds, butt welds, and shell to annular welds
Piping systems and pressure vessels
Tank bottoms
ERW seamed pipe in pipelines
Objects on which a pressure differential can be created across the area to be examined

Advantages

The main advantages of this service are:

Provides an immediate indication visual of the location of any leaks present
Can detect small leaks within a given area
