Abstract:

A means of attaching and supporting lagging that integrates attachment and support for both insulation and lagging. Angle irons are welded to the hot surface. Insulation pins are also welded to the hot surface at two different levels in a pattern that will support the insulation. The insulation is impaled on the insulation pins. A first subgirt is placed on the angle irons and welded at one end only to an angle iron. The insulation pins are received and extend through bores in the first subgirt. A second subgirt is received on insulation pins at a different level. A fastener is installed oil the end of each insulation pin to hold the subgirts against the outer surface of the insulation. The end of each pin is bent to retain the fasteners in place. The lagging panels are bolted to the subgirts.
