24、significant loss of mechanical properties.4. Significance and Use4.1 This standard is intended to be used by engineers anddesigners as a guide to assist them in selecting appropriatethermal insulation jacketing materials. As a guide, it can beused to identify performance characteristics that might b

25、enecessary for a particular insulation jacketing system. Thisguide is not a specification and therefore should not be used assuch. It might, however, be useful in writing a specification.Specification C921 can also be used to determine properties ofjacketing materials for thermal insulation.5. Mater

26、ials and Manufacture5.1 Jacketing materials may be composed of a single mate-rial or a lamination of several components. The material maybe in the form of rolls or sheets or preformed to fit the surfaceto which they are to be applied. The materials may be appliedin the field or may be a factory-appl

27、ied composite with theinsulation.5.2 Metallic:5.2.1 Metallic jacketing materials are those whose primarymaterial (usually the component of greatest thickness) is metal,such as, aluminum, coated steel, and stainless steel. The metalmay be smooth, corrugated, or embossed. The dimensions ofcorrugations

28、 (pitch and depth) may be specified by the pur-chaser for interchangeability, constant rigidity, and control ofsizes. The inner surface of metallic jacketing materials may becoated or covered with a moisture resistant film to retardpossible galvanic and/or chemical corrosion of the jacketing.5.2.1.1

29、 Aluminum jacketing should be manufactured incompliance with Specification C1729 which incorporates byreference the chemical composition and physical properties ofSpecification B209. Where ambient conditions are particularlycorrosive or when a higher surface emissivity is desired, theouter surface o

30、f the aluminum may be coated with paint orplastic film.5.2.1.2 Coated steel jacketing materials can be manufac-tured in compliance with several Specifications includingA366/A366M and A1008/A1008M using alloys 1010, 1015, or1020 steel. The outer surface is typically protected byaluminizing, galvanizi

31、ng, or coating with another type ofcorrosion resistant metal alloy. Metal thicknesses generallyavailable are from 0.010 to 0.019 in. (0.25 to 0.46 mm).5.2.1.3 Stainless steel jacketing should be manufactured incompliance with Specification C1767 which incorporates byreference the chemical compositio

33、nufac-tured from combinations of plastic films, plastic composites,metallic foils, reinforcing fabrics, papers, or felts selected toobtain the required performance characteristics. Laminatedjacketing for outdoor applications should be manufactured incompliance with Specification C1775.5.3.1.1 One co

Thicknesses generally available are from0.003 to 0.035 in. (0.08 to 0.89 mm). Various materials can beused such as poly-vi

36、tal chloride (PVC), CPVS, fiberglassreinforced plastic (FRP), and others.5.3.4 Saturated felt or cloth jacketing materials are manu-factured from various base felts or cloths that have beenimpregnated with bitumen or resinous materials. Examples:Glass fiber, polyester fiber, polyolefin fiber. This d

Physical and Chemical Performance Considerations6.1 This section includes a number of performance issuesthat should be considered when using this guide to select ajacketing material for thermal insulation. Some may not beapplicable to the particular application. However, to be cert

44、ainnone are overlooked, the user should consider all materialsinitially and then eliminate those that are not applicable.6.2 Abuse ResistanceConsideration should be given to theability of a jacketing material to withstand a variety of physicalconditions in excess of required functional design criter

45、ia.Prior to selection, consideration should be given to the ex-pected intensity and types of abuse as well as the length of timethe jacketing material is expected to withstand a given level ofabuse.6.2.1 Abuse May Include the Following Factors:6.2.1.1 Foot traffcWill people or equipment be applyingl
