vacuum box Testing


Kaztron ndt Pvt Ltd offers Vacuum Box Testing services for a variety of industries. This testing method is used to detect and locate leaks in pressure vessels, pipelines, and other pressure containing equipment, including storage tank bottom and annular plates.

Vacuum Box Testing is a non-destructive method of testing that uses a vacuum to detect leaks. A vacuum is created inside a sealed chamber and the pressure difference between the inside and outside of the chamber is monitored. Any leaks will result in a pressure drop inside the chamber, indicating the presence of a leak.
