KALCOR pipes and pipe bends

Zirconium corundum

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, thereby enabling the production of asymmetrical cross-sections.

Suitable flange connections make it easy to join KALCOR pipes and pipe bends to other existing lines.
