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.
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.

With fused cast basalt and ceramics, Kalenborn relies on natural materials that are renewable. After the worn lining has been removed, its materials are recycled and fed back into the process for manufacturing new wear-resistant materials.
