Significance and Use4.1 When choosing a thermal insulation product or combi-nation of products, physical,
36、 chemical and mechanical proper-ties and the significance of those properties should be consid-ered. ASTM test methods are usually performed underlaboratory conditions and may not accurately represent fieldconditions depending on process temperature, environment,and operating conditions. Performance
37、 results obtained usingASTM test methods can be used to determine compliance ofmaterials to specifications but do 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 v
38、alues may exist forspecific material applications.4.2 Design of thermal insulation systems requires the un-derstanding of process requirements, temperature control, heatloss criteria, control of thermal shock, and mechanical forceson insulation generated by thermal gradients and wind envi-ronmental
39、conditions. Sometimes, the mechanical design ofpiping and equipment needs to be modified to support insula-tion adequately and provide for insulation weatherproofing.Process requirements may dictate the control of critical tem-perature to prevent freezing, maintain viscosity, or minimizeinternal cor
40、rosion. When handling heat transfer fluids such asethylene oxide or hot oils, the selection of insulation materialsand the insulation system design becomes critical. whereby Ifthese fluids are absorb in insulation materials, the fluid flashpoint could be below the fluid operating temperature. Specif
41、iedheat gain or heat loss and acceptable surface temperaturescould also dictate thermal design of insulation systems. 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 as
42、ignificant role in the selection of insulation materials andapplication methods to provide long-lasting trouble-free ser-vice.4.3 Application methods are generally defined by the pur-chasers specifications. However, some specialty insulationsystems, such as prefabricated insulation panels for ductwo
43、rk,precipitators, and tanks, will also have supplemental installa-tion requirements specified by the insulation system manufac-turer. defined by the specification of the manufacturer.4.4 In any application of thermal insulation, the insulationrequires protection of some type, be it protection from t
44、heelements such as rain, snow, sleet, wind, ultraviolet solarradiation, protection from external forces that can causemechanical damage, vapor passage, fire, chemical attack, orany combination of these. This protection can be provided inby metal, plastic, coated or laminated composites or both,masti
45、c coatings, or a combination of the above depending uponthe application, service, and economic requirements. Consid-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 o
46、peratingcost as a result of inefficient insulation protection, it is commonsense to provide only the best insulation 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 th
47、e initial cost of theinsulation portion is a small percentage of that overall cost.However, increased operating costs 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 recom
48、mended that the purchaser provide a qualityassurance program that defines the inspection of all materials,material 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 di
49、scuss and agree to the procedures to be adoptedfor suitable periodic inspection and maintenance of the insu-lation systems to ensure that the initial performance of thematerial will be maintained. And, where applicable, theyshould agree to the methods of repair and replacement to beadopted in case damage occurs during service or overhaul.5.
