Aluminum heat treater anodes are sacrificial anodes installed in heat treaters, pressure vessels and other production vessels, which are compact and easy to be replaced periodically. 

It's an optimum solution for cathodic protection in relatively high temperature and low chloride saltwater environments. The most common types are in the shapes of cylindrical and spherical. 

A threaded steel core is centered into the cylindrical anode for supporting and mounting. Eyebolt core is also available upon request. The extended end of the steel core could be hung and mounted on the top of the tank or vessel. Furthermore, it's also welded with the lead cable and completely sealed by epoxy at the joint.
