KALFLEX® Wear Resistant Flexible Pipe Systems

Effective Wear Protection in Pipes and Elbows Adapts to Movement Quickly and Easily

KALFLEX® wear resistant flexible pipe system for wear protection in conveying system components.KALFLEX wear resistant flexible pipe systems provide a cost effective solution for connecting conveying system components that move due to vibration, thermal expansion, or as a result of intended movement. The flexible pipe systems can be easily integrated into existing pipe systems using normal flanging and works well in pneumatic conveying equipment. The elbows are useful in replacing worn components of undetermined angle or radius.

The interior of flexible KALFLEX is composed of individual wear resistant segments to provide flexibility. The pipes and elbows are enclosed in an engineered rubber jacket to ensure stability and tightness. Depending on the application, KALFLEX lined piping components can be supplied with KALMETALL®-C hard cast iron or KALOCER® high alumina ceramic for wear protection.

KALFLEX Components Lined with KALMETALL®-C or KALOCER® Protect Pipe and Bends From Extreme Wear


KALFLEX® lined piping and elbows can be lined with KALMETALL®-C or ALRESIST®. KALMETALL®-C For Impact Wear and Sliding Abrasion

KALMETALL®-C hard cast iron segments are used in KALFLEX components to withstand wear from impact and sliding abrasion. Select from a variety of alloying compounds with hardness from 580-700 HV, to optimize protection in specific applications. Diameters range from 20 mm to 150 mm (.79" to 5.91") ID.

KALOCER® For Use in Extreme Wear

KALOCER alumina oxide ceramic segments with a Moh’s hardness of 9, are used in KALFLEX components exposed to extreme abrasive wear. When KALOCER® is used, the end segments are made of KALMETALL®-C and the flanges are carbon steel for strength. Diameters range from 50 mm to 100 mm (1.97" to 3.94") ID.
