Innovation at WAFO WAFO bi-metal cylinders for highest demands

process controlled bi-metal centrifuging plant.

Through the use of a tried and tested line inductor, a carrier pipe is materially carefully heated up and in a second stage subjected to a high rotation rate. Through this so-called centrifugal swing, the embedded hard material alloy binds into a uniform diffusion zone with the carrier pipe. In combination with a thought out process technique a stress relieved end product results with regular qualities, as well as for the inside cladding as for the carrier material.

According to the operation and application conditions different centrifuging alloys are developed. The carrier materials were foreseen beforehand with a safety coefficient of 1,2 with respect to the cylinder hardness and the high-temperature limit of elasticity.
