Significance and Use4.1 When choosing a thermal insulation product or combination of products, physical, chemical and mechanical properties andthe significance of those properties should be considered. A

37、STM test methods are usually performed under laboratory conditionsand may not accurately represent field conditions depending on process temperature, environment, and operating conditions.Performance results obtained using ASTM test methods can be used to determine compliance of materials to specifi

38、cations but donot necessarily predict installed performance. Values stated in the ASTM material standards are those that apply to the majorityof materials and not to any specific product; other tested values may exist for specific material applications.4.2 Design of thermal insulation systems requir

39、es the understanding of process requirements, temperature control, heat losscriteria, control of thermal shock, and mechanical forces on insulation generated by thermal gradients and wind environmentalconditions. Sometimes, the mechanical design of piping and equipment needs to be modified to suppor

40、t insulation adequately andprovide for insulation weatherproofing. Process requirements may dictate the control of critical temperature to prevent freezing,maintain viscosity, or minimize internal corrosion. When handling heat transfer fluids such as ethylene oxide or hot oils, theselection of insul

41、ation materials and the insulation system design becomes critical. whereby If these fluids are absorb in insulationmaterials, the fluid flash point could be below the fluid operating temperature. Specified heat gain or heat loss and acceptablesurface temperatures could also dictate thermal design of

42、 insulation systems. Environmental corrosivity, high wind, and extremeambient temperatures affect the selection of weatherproofing and methods of its securement. A combination of these factors playsa significant role in the selection of insulation materials and application methods to provide long-la

Considering the enormous overall cost of a new facility, and comparing the initial cost of the insulated portion asa small percentage of that overall cost with the substantially increased operating cost as a result of inefficient insulat

Usually a new facility is very expensive and the initial cost ofthe insulation portion is a sm

However, increased operating costs can result from inefficientprotection.4.5 Bid invitations should contain information necessary to determine how guarantees of materials and application will beresolved.4.6 It is recommended that the purchaser provide a quality assurance program that defines the inspection of all materials,material safety data sheets (MSDS), and specific application procedures before and during progress of the insulation work.4.7 During contract negotiations, the contractor and purchaser should d
