External scanning methods only. No access to bore.

You may use ultrasonic shear wave technique, I will assume per your message that cracks runs parallel to the pipe axis. In this case you may manufacture a special transducer that fit the outer surface of the pipe, and perform the scan in order to detect on the first leg in case that cracks start at the inner surface. You may also manufacture a standard with the same geometry and material of the pipe you are inspecting. You may ask to machine several EDM notches of different lenght and depth so you can evaluate the response of your UT system. Hope that help a little Best regards ----------- Start Original Message ----------- : Greetings : Looking for a solution to detect longitudinal cracks in "in-service" pipelines 6"-12" OD, Wall thickness 12-14mm.

If possible with limitations of service condition and temprature you can go for gamma ray. ---------- Start Original Message ----------- : Greetings : Looking for a solution to detect longitudinal cracks in "in-service" pipelines 6"-12" OD, Wall thickness 12-14mm.
