Detect flaws in pipeline infrastructure during construction or over the passage of time. Detect flaws such as construction defects, corrosion, ground movement, hot-tap made by error, and others.
- Inspect sewers
Inspect sewage drains in order to detect explosive gases using gas analysis equipment.
- Examine civil structures
Perform non-destructive testing on civil structures such as bridges and pipelines in order to find abnormalities or damage.
- Record test data
Record data which has been identified specifically during preceding tests in order to verify that outputs of the test produce specific results or to review the reaction of the subject under exceptional or unusual input.
- Prevent pipeline deterioration
Ensure the conservation of pipelines by undertaking adequate maintenance of the system and its coating properties. Prevent corrosion formation, leaks, and other problems.
