36、gnificance 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 methods are usually performed underlaboratory conditions and may not accurately repres

37、ent 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 not necessarily predictinstalled performance. Values stated in the ASTM materialsta

38、ndards 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-derstanding of process requirements, temperature control, heatloss criteria, control of th

39、ermal 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 adequately and provide for insulation weatherproofing.Process requirements may dictat

40、e 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 materialsand the insulation system design becomes critical. whereby Ifthese fluids are abso

41、rb 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 systems. Envi-ronmental corrosivity, high wind, and extreme ambient tem-peratures affect

42、 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-free ser-vice.4.3 Application methods are generally defined by the pur-chasers specif

43、ications. 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 system manufac-turer. defined by the specification of the manufacturer.4.4 In any app

44、lication of thermal insulation, the insulationrequires protection of some type, be it protection from theelements such as rain, snow, sleet, wind, ultraviolet solarradiation, protection from external forces that can causemechanical damage, vapor passage, fire, chemical attack, orany combination of t

45、hese. 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. Consid-ering the enormous overall cost of a new facility, and compar-ing the initial cos

46、t 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 insulation system available andthe best protection for that long-term investment consistent

47、with 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 costs can result from inefficientprotection.4.5 Bid invitations should contain inform

48、ation 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 safety data sheets (MSDS), and specific applicationprocedures before and during pr

49、ogress of the insulation work.4.7 During contract negotiations, the contractor and pur-chaser should discuss 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.
