GEROtec MININGAbrasion-resistant pressure pipe for mining and open-cast mining

The inner protective layer guarantees long-term resistance to abrasive wear when transporting media containing solids. Available in 2-layer (GEROtec MINING I) or 3-layer (GEROtec MINING II) pipe wall construction. The economical alternative to traditional materials in industrial, plant and mining applications.

Suitable Installation

Sand bedding

When laying in a sand bed, the excavated material must be replaced with a sand bedding in accordance with DIN EN 805. Restrictions on the grain sizes of the bedding material must be observed.
Without sand bedding

Due to the verification by an independent testing institute, the installation is possible without a sand bed. This eliminates the additional expense of replacing the excavation with a sand bedding in accordance with DIN EN 805 (transport, landfill).
Ploughing

In the ploughing method, the soil is displaced by a plough blade and the pipeline is placed on the bottom of the soil.
Milling

In the milling process, a pipe trench is cut into the subsoil by machine and the pipeline is laid on the bottom of the trench.
