GREEN pipes with replaceable wear protection lining
In hydraulic and pneumatic conveying applications, abrasive materials such as ash, sand or sinter dust cause steel or cast iron pipes to wear. Lining them with wear-resistant materials extends service life and reduces maintenance costs.
Green pipes and pipe bends have a wear-resistant lining that can be removed and recycled at the end of their service life. The wear-resistant lining’s special mounting concept makes it possible to remove the old lining without destroying the steel shell. The existing steel pipes are subsequently relined with new material cylinders.
The method used gives the lining the same service life as conventionally lined pipes and pipe bends.
Wear-resistant green pipes: Sustainable and economical
Returning the worn pipes and pipe bends to Kalenborn eliminates disposal costs and no expenses are incurred to manufacture new steel pipes. Companies reduce their CO2 load on the environment.

Clever wear protection monitoring KALDETECT protects
KALDETECT electric is a good prerequisite for the smooth replacement of the wear protection lining in green pipes.
It gives the operator an early indication when the protective lining is worn, thereby keeping the steel pipes from becoming damaged and preventing possible environmental damage.
The wear protection lining is equipped with a low-voltage measuring conductor. If the lining inside the pipe is worn through by abrasion at any point, the conductor is interrupted and suitable evaluation logic identifies the affected section of piping. An alarm is triggered and the plant can be shut down automatically.

KALDETECT electric is a measurement system with CE approval by TÜV. It meets basic safety requirements and has an IP 66 protection rating (dust-tight and protected against powerful water jets).
