Ultrasonic Inspection: Types of Non-Pressurized Vessels & Systems

CTRL Innovation

Storage Tanks - This can include any number of types of tanks including gas, liquid, or any other type of tank. In some cases, such as Hazmat, it is very important that tanks do not leak. Some States have laws governing the leak rates of storage tanks.
Pipes - Although pipes usually have some sort of pressurized gas, it can be advantageous at times to test the pipes when the system is completely void. Appropriate testing times would be during installation or performing air surveys when production is not scheduled.
Door & Window Gaskets - One of the highest warranty claims in the auto industry is leaking windshields.
Bulkhead & Hatch Seals - One old method to test for the integrity of hatches was to outline the hatch with chalk and blow air from the inside.
Windshields & Weather Stripping - Windshield replacement can be a highly profitable service, but rework can be a major drawback.
Cleanrooms - Used for labs, and in manufacturing of semiconductors, electronics, and other products that require no contamination, it is important to keep a cleanroom sealed.
Railroad Cars & Truck Cabs - This category includes any transportation of hazardous materials, refrigerated cars, and climate controlled passenger cars and truck cabs.
