1、Designation: C1696 15Standard Guide forIndustrial Thermal Insulation Systems1This standard is issued under the fixed designation C1696; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parenthe

2、ses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This guide covers information on selection of insulationmaterials, systems design, application methods, protectivecoverings, guarantees, inspection, test

3、ing, and maintenance ofthermal insulation primarily for industrial applications in atemperature range of -320 to 1200F (-195.5 to 648.8C).1.2 This guide is intended to provide practical guidelines,by applying acceptable current practice while indicating thebasic principles by which new materials can

4、 be assessed andadapted for use under widely differing conditions. Designengineers, the general contractors, the fabricators, and theinsulation contractors will find this guide helpful.1.3 Although some insulation system designs can serve asfire protection, this guide does not address the criteria s

5、pecificto that need. API 521 Guide for Pressure-Relieving andDepressuring Systems is recommended as a reference for fireprotection. This guide will however address the fire propertiesof insulation materials.1.4 This guide is not intended for commercial, architectural,acoustical, marine, vehicle tran

6、sport, or military use.1.5 This guide does not address insulation system design forrefractory linings or cold boxes whereby these are typicallypackage units and of a proprietary insulation design.1.6 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses

7、 are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.7 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safe

8、ty and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Significance and Use4.1 When choosing a thermal insulation product or combi-nation of products, physical, chemical and mechanical proper-ties and the significance of those properties should be consid-ered. ASTM test met

37、hods are usually performed underlaboratory conditions and may not accurately represent fieldconditions depending on process temperature, environment,and operating conditions. Performance results obtained usingASTM test methods can be used to determine compliance ofmaterials to specifications but do

38、not necessarily predictinstalled performance. Values stated in the ASTM materialstandards are those that apply to the majority of materials andnot to any specific product; other tested values may exist forspecific material applications.4.2 Design of thermal insulation systems requires the un-derstan

39、ding of process requirements, temperature control, heatloss criteria, control of thermal shock, and mechanical forceson insulation generated by thermal gradients and wind envi-ronmental conditions. Sometimes, the mechanical design ofpiping and equipment needs to be modified to support insula-tion ad

40、equately and provide for insulation weatherproofing.Process requirements may dictate the control of critical tem-perature to prevent freezing, maintain viscosity, or minimizeinternal corrosion. When handling heat transfer fluids such asethylene oxide or hot oils, the selection of insulation material

41、sand the insulation system design becomes critical. whereby Ifthese fluids are absorb in insulation materials, the fluid flashpoint could be below the fluid operating temperature. Specifiedheat gain or heat loss and acceptable surface temperaturescould also dictate thermal design of insulation syste

42、ms. Envi-ronmental corrosivity, high wind, and extreme ambient tem-peratures affect the selection of weatherproofing and methodsof its securement. A combination of these factors plays asignificant role in the selection of insulation materials andapplication methods to provide long-lasting trouble-fr

43、ee ser-vice.4.3 Application methods are generally defined by the pur-chasers specifications. However, some specialty insulationsystems, such as prefabricated insulation panels for ductwork,precipitators, and tanks, will also have supplemental installa-tion requirements specified by the insulation sy

45、ausemechanical damage, vapor passage, fire, chemical attack, orany combination of these. This protection can be provided inby metal, plastic, coated or laminated composites or both,mastic coatings, or a combination of the above depending uponthe application, service, and economic requirements. Consi

46、d-ering the enormous overall cost of a new facility, and compar-ing the initial cost of the insulated portion as a small percentageof that overall cost with the substantially increased operatingcost as a result of inefficient insulation protection, it is commonsense to provide only the best insulati

47、on system available andthe best protection for that long-term investment consistentwith the appropriate design and economic requirements. Usu-ally a new facility is very expensive and the initial cost of theinsulation portion is a small percentage of that overall cost.However, increased operating co

48、sts can result from inefficientprotection.4.5 Bid invitations should contain information necessary todetermine how guarantees of materials and application will beresolved.4.6 It is recommended that the purchaser provide a qualityassurance program that defines the inspection of all materials,material

49、 safety data sheets (MSDS), and specific applicationprocedures before and during progress of the insulation work.4.7 During contract negotiations, the contractor and pur-chaser should discuss and agree to the procedures to be adopted6Available from National Fire Protection Association (NFPA), 1 BatterymarchPark, Quincy, MA 02169-7471, http:/www.nfpa.org.7Available from the U.S. Government Printing Office, Superintendent ofDocuments, 732 N.
