Wear Resistant

Systems
One of the main areas for wear in a
conveying system is the pipework itself.
It is now possible to install a true “fit and
forget” solution using stainless steel
straights and glass bends. Even the
vacuum line has stainless steel elbows
and of course all flexible hoses are wear
resistant. One of the main causes of pipe
work wear is too high a conveying speed
