Zirconium corundum ceramics KALCOR pipes

Wear-resistant pipes for very high abrasion resistance at very high thermal shock resistance

Wear-proof KALCOR pipe systems are extremely abrasion-resistant, withstand service temperatures up to +400 °C, and also provide good resistance to temperature changes. The cast pipe cylinders are made of zirconium corundum with wall thickness as thin as 12 mm. Kalenborn also manufactures lined pipe bends from cast parts.
