Providing numerous examples of sheet metal lagging applications, this publication assists the designer, contractor and plant engineer in understanding and solving the complexities involved in the design, fabrication and installation of sheet metal lagging systems. It presents accepted industrial practices for the application of sheet metal lagging to industrial duct, pipe, tanks, boilers, furnaces and other accessories. Also illustrates the requirements of the most commonly encountered insulated surfaces, such as boiler walls, flues, ducts, precipitators, air heaters, economizers, tanks and fans.
