Testing chemical injection lines (CIL) with eddy current serves protecting against grooves, cracks and mechanical damages during the production of semi-finished parts and completion, and has already been successfully implemented by DELTA TEST for more than 10 years.
The test device is designed in such a way that the line can be tested during coiling up or down as initial or maintenance inspection without interfering with the normal workflow. For this, the test is performed with several sensors as well as position encoding sensors, so that the position of defects can also be determined retrospectively.
DELTA TEST does also have a special probe system with exchangeable powerful encircling coils for the inspection of special coil tubings mainly used in the oil and gas industry. Coil tubings have a similar design compared to chemical injection lines but a bigger diameter. Our equipment is suitable for ferritic or non-ferritic materials with a diameter range from 19.05 – 50.8 mm (3/4“ – 2“).
