1. Scope

1.1 This guide describes construction and installation of prefabricated panel insulation systems for vessels, ducts, and equipment operating at temperatures above ambient. Typical applications include, but are not limited to, power plant ducts, steam generating units, precipitators, bag houses, fans, refinery storage tanks, process vessels, and coke drums.

1.2 The insulation described herein is limited to systems consisting of insulating units specially designed to fit the surfaces to be insulated, and engineered for the service requirements.

1.3 Each insulation unit is a prefabricated construction typically comprised of insulation, an outer lagging to which the insulation is attached, an inner metal mesh and foil lining, and means for securing multiple units together in an assembly.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Note 1When prefabricated panel systems are specified, Test Methods C 167, C 177, and C 1061, and Terminology C 168 should be considered.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
