Continuous Thickness Control of Centrifugally Cast Concrete Pipes by an Ultrasonic Echo-System
Large diameter pipes of prestressed concrete with a length of 10–20 ft. used for water transport are made in rotating moulds. To control the thickness of these concrete pipes during production, an ultrasonic pulse-echo system mounted at the end of the feeder is used. Basically, the air gap between f...
