pwht ceramic beads


Our alumina ceramic beads for PWHT is high temperature resistance, excellent insulating property, and efficient thermal conductivity and heat transfer,higher density, higer surface finish and better uniformity, and be repeatedly used much longer

PWHT ceramic beads is widely used as components of flexible ceramic heating pad(ceramic pad heater) and channel heaters at operation of pre and postweld heat treatment; welding process, stress-relieving, ship-building, other heat-resistance-environment. pwht alumina ceramic beads
