Metal-On was a Johns-Manville pipe insulation that came from the factory already jacketed in metal.1,2 J-M's 1970 sworn answers in a lawsuit describe it as Thermobestos pipe insulation "with a factory-applied jacket of aluminum," and a 1970 item in Asbestos, the industry's trade journal, as a factory-assembled system of an aluminum jacket, a vapor barrier and Thermobestos insulation, snapped over bare pipes and held with straps and stainless steel bands.1,3 J-M's employee magazine said in 1961 that its Research Center had "married" Thermobestos, its calcium silicate pipe insulation, with J-M's metal-forming experience to make a weatherproof insulation for high or low temperature pipes.4 A 1960 photo in the same magazine shows a version with a stainless steel jacket.5
An insurance company's 1981 list of asbestos products, compiled from other companies' answers in lawsuits, gives Metal-On, listed as pipe, as made from 1959 to 1973.6 J-M's employee magazine mentions Metal-On production at the Manville, New Jersey plant in December 1959, and in 1961 shows a worker in the Manville Industrial Insulations Plant forming the aluminum jacket to fit over the Thermobestos.4,7 In 1967 Asbestos magazine reported Metal-On produced by Canadian Johns-Manville, for temperatures up to 1,200°F.8
J-M said in 1961 that Metal-On was used on the wash decks of tankers, on smoke stacks and outdoor steam lines, and in chemical and power plants.4 It was used throughout the piping of Hydro-Quebec's new thermal generating station at Tracy, Canada, in 1966, except on the boiler piping, and at an Atomic Energy of Canada laboratory in Ontario in 1967.8,9 A 1971 J-M ad said "asbestos fibers added increased strength and fire-safety" to the Metal-On on the external deck piping of the ship Manhattan.2
