WEAR-RESISTANT QRB PIPE BENDS

Wear protection for the pneumatic handling of abrasive bulk materials

In 1998 the impact absorbers in a gas concrete factory were replaced with Kurz Tribotechnik pipe bends. Since then the pipe bends have given trouble-free service, most of the time in three-shift operation.
As a result of this action the unloading times of silo trucks have been reduced by approx. 30 minutes per vehicle per stop. This upgrade alone has achieved a saving of around 1.5 million Euro in the past 12 years. This does not take account of the downtimes that have been eliminated or the energy saved by reducing the compressor power. These pipe bends are still in operation.

A number of demands were made on the pipe bends when approaching a solution to the problem

1. High utilisation factor

2. Ease of replacement

3. Wear-resistant geometry

4. Distribute, not concentrate

5. Use of a suitable material in a
„material-optimised“ design
