ASTM C667環境溫度空氣以上管道操作和設備預制纖維反射絕緣標準規范
ASTM C667 Standard Specification for Prefabricated Reflective Insulation Systems for Equipment and Pipe Operating at Temperatures above Ambient Air
ASTM C667環境溫度空氣以上管道操作和設備預制纖維反射絕緣標準規范
This specification covers the standard for all metal prefabricated, reflective insulation systems for equipment and piping operating at temperatures above ambient in air proposed for use in nuclear power-generating plants and industrial plants. The insulation unit is a rigid, self-contained, prefabricated metal construction made of an inner and outer casing arranged to form a rigid assembly with separated air spaces between the inner and outer casing and the individual reflective liners. The reflective insulation described herein is limited to systems of insulating units, designed to fit the equipment or piping to be insulated. The units shall be manufactured from metals that are in accordance with the thermal, physical, and chemical requirements not only of the insulation as unit, but also as an assembly of units forming the insulation system.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1. Scope
1.1 This specification covers the requirements for all metal prefabricated, reflective insulation systems for equipment and piping operating in air at temperatures above ambient. Typical applications are in nuclear power-generating plants and industrial plants.
1.2 Reflective insulation is thermal insulation that reduces radiant heat transfer across spaces by the use of surfaces of high reflectance and low emittance.
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 and health practices and determine the applicability of regulatory limitations prior to use.
