Wall thickness measuring device
Note ___________________________________________________________________
Delivery lines are subject to constant wear. Measurement of the wall thickness is
particularly important before starting on large jobs. You will obtain reliable results for your
measurements if you carry out the test with the measuring device recommended by KCP

Danger of explosion ______________________________________________________
The delivery line can burst if it reaches the right delivery pressure, particularly if a
blockage has built up and, if the wall thickness of the delivery line has declined below the
minimum requirements.
_______________________________________________________________________
Caution ________________________________________________________________
Only tap the delivery line with hardwood (hammer handle). Otherwise dents may be
caused which lead to even faster wear. In addition, the hardening lining of high wear
resisting pipes may flake off the inside of the pipe. The pipe can burst at points that have
suffered heavy wear.
