Highly Specialized & Appropriate Non-Destructive Testing
Do You Have A Project We Can Help With?
Role of Non-Destructive Testing
- Detection of material characteristics which renders a part to be unsuitable,
unsafe or unusable for the intended purpose. - Describes any local variation in material geometry on the basis of physical, chemical or
metallurgic properties. - Increases productivity, serviceability, and reliability.
- Ensures safety.
- Determines the integrity of a component.
- To comply with the requirements of laid down specifications.
- To comply with law requirements.
Magnetic Particle Inspection
Process for detecting surface and sub-surface discontinuities in ferro-electric material by using an electric field.
Advantages
- Best method for detecting fine, shallow surface cracks
- Fast method
- Very little limitations in respect to the size/shape of the test part
- Very portable method
Components Tested
- Winder brake components
- Sheave wheels
- Rope attachments
- Rigging and lifting equipment
- Conveyance components
- Winder gearboxes
- Compressor parts
- Main/booster ventilation fans
- Chairlifts
- Winder drum shafts
- Large mills
Ultrasonic Inspection
In ultrasonic testing, very short pulse-waves are launched into materials to detect internal flaws or characterize materials.
Advantages
- Works well for cracks, lack of fusion, porosity and inclusions
- Excellent for laminations or discontinuities parallel to the surface
- It can be used on a wide variety of materials
- It has very high penetration capabilities
- Very portable method
- Gives immediate results
Components Tested
- Winder brake components
- Sheave wheels
