Pipe Wet Mortar Lining Thickness Measurement

We are developing a Remote Lining Machine to apply cement mortar to the inside of a steel water pipeline, and seek a sensor to provide (wet) lining thickness feedback, in real time. Our pipes have been pre-cleaned using a recently developed water blasting system, back to the steel. Typically our pipes are 760 mm diameter (could be 600 mm, or >1m), with a 6.5 mm nominal wall thickness, but with considerable corrosion variation and pitting. Our machines use a mortar-supplied spinner head at the rear to apply and build up the wet lining, then trowel downstream for a smooth finish as the machine is withdrawn from the pipe. Typical target lining thickness is 15 mm, which we seek to hold to 1 mm or so. Co-ordinated access to the outside of the pipe would prove difficult. S.G of mortar approximately 2.5.

Hope the experts can suggest options, or recommend alternatives!

We may have an option for you, but you mentioned that access to the OD would prove difficult. Please contact me to discuss in more detail.

Thanks,

SONOAIR - air-coupled Phased Array Ultrasonic Inspection System

For highly attenuating materials, the performance of the system is critical. The ultrasonic sensors,
...
the scanning area and the system settings should be flexibly adapted to the test task and the material. These high expectations are met with the new and modular testing system SONOAIR. With the world’s first air-coupled phased-array UT inspection system SONOAIR we developed a technology that works with up to 4 transmitter and receiver channels with freely configurable square wave burst transmitters as wells as low noise receiving amplifiers.
