Pressure Vessel
Pressure vessels are industrial containers designed to hold vapors, liquids, or gases.
Who we are
Pressure Vessel Inspections


Inspections are a crucial part of the maintenance process for pressure vessels.
This section covers information on the frequency with which inspections should happen, what is done during inspections, the types of testing that can be used in inspections, and ends with a checklist of what is generally covered during a pressure vessel inspection.
FREQUENCY OF INSPECTIONS
Most pressure vessel regulations provide specific requirements for the frequency of inspections. As a general rule of thumb, pressure vessels should be inspected at least once every five years. An inspection should also be conducted once the vessel is installed, prior to it being put into service.
Whats We Do
VISUAL TESTING

ULTRASONIC TESTING
Ultrasonic testing uses sound waves to measure the thickness of a material’s surface in order to detect any defects that may have arisen. This kind of testing is volumetric, meaning it can detect flaws inside the vessel as well as on its surface. Learn more about ultrasonic testing.

RADIOGRAPHIC TESTING
Radiographic testing uses radiography to detect defects near the surface or on the surface of a vessel. This testing method is also volumetric. Learn more about radiographic testing.

MAGNETIC PARTICLE TESTING
Magnetic particle testing uses magnetic current run through the pressure vessel to identify deformations or defects on the surface of the vessel, which will interrupt the flow of the magnetic current and appear as a “flux leakage field.” Learn more about magnetic particle testing.

DYE PENETRANT TESTING
Dye or liquid penetrant testing uses liquid (i.e., the penetrant) sprayed onto the vessel to identify defects or flaws on its surface. A fluorescent chemical can be added to the penetrant to make flaws visible under U.V. light. Learn more about dye penetrant testing.
