Vacuum Box Testing – VBT

Vision Integrity provides Vacuum Box Testing (VBT) throughout Western Canada and has several dispatch locations operating 24/7.

Vacuum Box Testing is a nondestructive testing method that is used to locate weld seam leaks. Vacuum Box Testing uses a vacuum box and compressor to create high or low pressure vacuum while a detergent solution is applied to test the area. The detergent creates bubbles when a leak has been located. Vacuum Box Testing is primarily used with tank floors, ERW seamed pipe in pipelines, pressure vessels, welds etc.
