This practice provides the design and dimensional details required for the proper selection of the type of, and correct installation procedures for, thermal insulation materials suitable for use on piping, machinery, and equipment employed in nonnuclear shipboard applications. The insulation and lagging requirements for the removable covers of valves, fittings, flanges, and machinery or equipment, as well as the requirements for thermal insulating tape, are also detailed completely.
1.1 This practice covers the selection of types and thicknesses of thermal insulation materials for piping, machinery, and equipment for nonnuclear shipboard applications within the temperature ranges specified in Tables 1-16. Methods and materials for installation, including lagging, are also detailed.
1.2 This practice addresses operating temperatures from a low of –20 °F (–29 °C) up to 1200 °F (649 °C).
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
