Ultrasonic Inspection is a non-destructive testing method capable of detecting both surface and sub-surface flaws in components and welds. UT can also be used to measure the thickness of materials, a common method of evaluating metal losses due to corrosion or erosion.
KAOTHEEM APPLIES UT
- To determine the extent of internal and/or external corrosion/erosion in process piping and pressure vessels
- For new fabrication weld inspection to verify code compliance:
– ASME Section V for pressure vessels
– ASME B31.1 and B31.3 for piping
– API 1104 for pipelines
ADVANTAGES
- Ultrasonics can be used to detect, locate and characterize flaws that other NDE methods cannot:
– Some capabilities of determining the size, orientation and nature of internal flaws
– High penetrating power for detection of defects deep in the material
– High sensitivity allowing for location of extremely small flaws
- Only one surface needs to be accessible
- Field Ready
– Systems are portable and battery powered
– Light enough to easily take onto scaffolding
– Non-hazardous to operations or other nearby personnel, and has no effect on equipment or materials in the vicinity
LIMITATIONS
- Parts that are rough, irregular in shape, or very small or thin are more difficult to inspect
- Surfaces must be prepared by cleaning and removing scale, loose paint etc. prior to inspection
- Manual operation requires careful attention by experienced technicians
