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head at the rear to apply and build up the wet lining, then trowel downstream for a smooth finish as the machine is withdrawn from the pipe.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,
