1. Ultrasound airborne – Leak Management
Ultrasound is an essential part of a proactive reliability program as it can reduce or eliminate wasted compressed air through leak detection and repair.
What Are Ultrasound Airborne Leak Detection Surveys?
Ultrasound Airborne Leak Detection Surveys cover a wide range of leaks: pressure or vacuum and any gas. Sound dependent, ultrasound instruments detect the turbulent flow produced as the fluid (liquid or gas) moves from the high-pressure side to the low-pressure side of a leak. Ultrasound leak inspection is especially beneficial in areas where there is a saturation of gases or where a wide variety of gases, pressurized vessels and vacuum processes exist. For this reason, ultrasound leak detection is used in many facilities for safety, environmental, energy or quality assurance programs.
We provide Airborne Leak Detection Surveys to identify the compressed air or gas leaks at your facility. The survey includes detailed reporting to help you repair each leak, which will save thousands of euro’s each year in energy consumption.
2. Ultrasound Lubrication
Maintenance Holding provides Ultrasound Lubrication, a Preventive Maintenance (PM) service, to assure proper lubrication of the rotating equipment bearings in your facility with routine surveys. From using Route based Ultrasound Technology for greased bearings to visual inspections for proper oil levels and oil integrity in oil lubricated bearings, we can give you the confidence that your rotating equipment lubrication is in good shape to assure proper bearing life and equipment reliability.
This technology is used to survey the greased bearings in a facility, this survey indicates which bearings require lubrication. When the bearings that require lubrication are identified, Ultrasound Technology is then used during the lubrication process of greased bearings to assure proper levels of lubrication. This technology measures the ultrasonic sound decibels and prevents over or under lubrication, which provides each individual bearing the proper amount of grease based on need not “blanket rules”.
3. Ultrasonic Thickness testing
Is used to determine the remaining plate thickness and therefore the integrity of steel, aluminium and general metal vessels, plates and pipe work.
Whilst the process is non-destructive, physical contact with the surface is required. Advancements in technology have removed the need for surface preparation and reading can now be taken through a painted surface.
The Ultrasonic Thickness Report is a separate detailed report and includes diagrams indicating where the readings were taken and the current state of the component. These reading can then be used for trending over time or compared against set standards to identify remaining life or wear rates within the system.
Application for Ultrasonic Thickness Analysis
There are two methods of receiving the ultrasound waveform, reflection and attenuation.
In reflection (or pulse-echo) mode, the transducer performs both the sending and the receiving of the pulsed waves as the “sound” is reflected back to the device. Reflected ultrasound comes from an interface, such as the back wall of the object or from an imperfection within the object. The diagnostic datacollector displays these results in the form of a signal with an amplitude representing the intensity of the reflection and the distance, representing the arrival time of the reflection.
In attenuation (or through-transmission) mode, a transmitter sends ultrasound through one surface, and a separate receiver detects the amount that has reached it on another surface after traveling through the medium. Imperfections or other conditions in the space between the transmitter and receiver reduce the amount of sound transmitted, thus revealing their presence. Using the couplant increases the efficiency of the process by reducing the losses in the ultrasonic wave energy due to separation between the surfaces.
