Blasch 99% Alumina Hex Ferrules are pre-engineered for each installation and come properly sized, accurately molded, and completely wrapped with all required fiber insulation. Installation is as simple as taking them out of the box and slipping them into the boiler tubes. No castable refractory is used between the Blasch Ferrules and only the most minimal amount is required around the periphery. Operators can save days on turnaround without the need to painstakingly install, and then cure out, large expanses of castable refractory.
Our 99% Alumina Hex Ferrules have several long term advantages over traditional INCOLOY ferrules and castable installations including absolute resistance to metal dusting and carbon monoxide corrosion.
