Vacuum Box Testing
Vacuum box bubble testing is one of the safest and most reliable non-destructive test methods. The vacuum box bubble test can locate leaks in test areas that cannot be directly pressurized. The test is performed by applying a detergent solution on the test area and creating a vacuum around the test surface by using external mechanism e.g. vacuum box. The detergent solution will bubble if there is any leakage through the test area.
On-site Radiography Processing
Marine Inspection Service can offer a portable darkroom which can mobilise to Western Australian rural and metro sites, and allows us to offer same-day processing and on-site results. This is perfect for smaller projects where full site office mobilisation is not practical.
Our custom built darkroom comes fitted with a film dryer, secure isotope storage, non-corrosive materials, viewing facilities, portable generator, darkroom lighting, and a built-in waste management system.
Spooling and Vessel Transportation
Marine Inspection Service can offer a 7.5m Flat Bed Truck to pick up and/or return items for Non-Destructive Testing. The recently refurbished tray is certain to prevent carbon contamination of your exotic materials, and with a craning capacity of 2.5T, MIS can help transport pipe spooling, structural frames, and pressure vessels for testing.
Costs for transport can be included in the quote for NDT services. Items which exceed the craning capacity can be arranged to be tested in the MIS yard, whilst still on the truck, eliminating the time needed for complex or heavy lifts.
Positive Material Identification
Positive Material Identification, commonly known as PMI can be performed using several test methods. MIS employs a simple non-destructive test method called X-Ray Fluorescence (XRF) by using Olympus analysers. These instruments are widely accepted by various industries, particularly the petrochemical industry where precision test results are paramount.
Holiday Testing
A Holiday Test, or a Coating Continuity test, is one of the non-destructive test method applied on protective coatings to detect unacceptable discontinuities such as pinholes and voids. The test involves checking of an electric circuit to see if the current flow is sufficient to complete the electrical circuit. A Holiday test or Continuity test is performed by applying low voltage (connected in series with an LED or noise-producing component such as a piezoelectric speaker) across the chosen path. If the electrical flow is detected then the test area is termed as conductive indicating presence of discontinuities such as pinholes and voids.
