Significance and Use4.1 When choosing a thermal insulation product or comb
38、ination of products, physical, chemical and mechanical properties andthe significance of those properties should be considered. ASTM test methods are usually performed under laboratory conditionsand may not accurately represent field conditions depending on process temperature, environment, and oper
39、ating conditions.Performance results obtained using ASTM test methods can be used to determine compliance of materials to specifications 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 s
40、pecific product; other tested values may exist for specific material applications.4.2 Design of thermal insulation systems requires the understanding of process requirements, temperature control, heat losscriteria, control of thermal shock, and mechanical forces on insulation generated by thermal gr
41、adients and wind environmentalconditions. Sometimes, the mechanical design of piping and equipment needs to be modified to support insulation adequately andprovide for insulation weatherproofing. Process requirements may dictate the control of critical temperature to prevent freezing,maintain viscos
42、ity, or minimize internal corrosion. When handling heat transfer fluids such as ethylene oxide or hot oils, theselection of insulation materials and the insulation system design becomes critical. whereby If these fluids are absorb in insulationmaterials, the fluid flash point could be below the flui
43、d operating temperature. Specified heat gain or heat loss and acceptablesurface temperatures could also dictate thermal design of insulation systems.

A combination of these factors playsa significant role in the selection of insulation materials and application method

However, some specialty insulation systems,such as prefabricated insulation panels for ductwork, precipitators, and tanks, will also have supplemental installation requireme

48、on from external forces that can cause mechanical damage, vaporpassage, fire, chemical attack, or any combination of these.This protection can be provided in by metal, plastic, coated or laminatedcomposites or both, mastic coatings, or a combination of the above depending upon the application, servi

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 insulation protection,it is common sense to provide only the best insulation system available and the best protection for that long-term investmentconsistent with the appropriate design and economic requirements. Usually a new facility is very expensive and the initial cost ofthe insulation portion is a s
