Significance and Use4.1 This

24、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 benecessary for a particular insulation jacketing system. Thisguide is not

25、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. Materials and Manufacture5.1 Jacketing materials may be composed of a single ma

26、te-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-applied composite with theinsulation.5.2 Metallic:5.2.1 Metallic jacketing mat

27、erials 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 (pitch and depth) may be specified by the pur-chaser for interchangeabili

28、ty, 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 Aluminum jacketing should be manufactured incompliance with Specification

29、 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 of the aluminum may be coated with paint orplastic film.5.2.1.2 Coated stee

30、l 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, galvanizing, or coating with another type ofcorrosion resistant metal alloy. Metal

31、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 composition and physical properties ofSpecification A240/A240M.4Available from Techn

33、 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 common type of laminated jacketing is flexiblelow permeance vapor retarders,

34、which should be manufacturedin compliance with Specification C1136.5.3.2 Textile or cloth jacketing materials are woven orknitted of textile yarns. Commonly available forms are 4, 6, or8 oz/yd2(0.14, 0.20, or 0.27 kg/m2) cotton canvas, variousweaves of glass fiber yarns, presized glass cloth, knit,

35、or wovenplastic fibers.5.3.3 Plastic jacketing materials are manufactured in vari-ous forms and types. Thicknesses generally available are from0.003 to 0.035 in. (0.08 to 0.89 mm). Various materials can beused such as poly-vital chloride (PVC), CPVS, fiberglassreinforced plastic (FRP), and others.5.

36、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 definitiondoes not include tar paper, asphalt paper, or other paperboardmate

37、rials or other products, such as rag felt, that are made outof waste and they do not represent a continuous and resistantbase for a jacketing.5.3.5 Rubber containing membranes are manufactured fromcombinations of layers of various rubber containing materialssuch as butyl rubber or rubberized bitumen

38、 with layers of othermaterials such as plastic films, metallic foils, reinforcingfabrics, or a combination thereof.5.4 Classifications used in jacketing specificationsEach ofthe various ASTM specifications for jacketing contains adifferent classification system appropriate for that material.While ea

39、ch individualASTM specification should be consultedfor the details, the general outlines for each of these systemsare shown below.5.4.1 Specification C1136 Flexible Low Permeance VaporRetarders,5.4.1.1 Classified into seven Types based on physical prop-erties and structural requirements,5.4.2 Specif

Physical and Chemical Performance Considerations6.1 This

43、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 certainnone are overlooked, the user should consider all materialsinitially and

44、 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 criteria.Prior to selection, consideration should be given to the ex-pected inten

45、sity 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 applyingloads directly on the jacketing material such as when piping isused like a l

46、adder?6.2.1.2 Impact ResistanceIs the jacketing material locatedwhere there is a probability of it being routinely struck byfalling tools or other objects or being hit by traffic moving by?6.2.1.3 System MaintenanceDoes the system that the jack-eting material is on require maintenance at regular int

47、ervalsthat would require the removal and reinstallation of thejacketing material?6.2.1.4 Puncture ResistanceIs the jacketing material eas-ily punctured? See 9.2.2.6.3 Weather ResistanceConsideration should be given tothe ability of a jacketing system to be exposed outdoorswithout a significant loss

48、of properties. Factors to consider inselection of the jacketing materials, that comprise the jacketingsystem, are the following.6.3.1 Possible effects of precipitation, including rain, snow,sleet, hail, frost, and dew as appropriate for the use area.6.3.2 Possible effect of ultra violet radiation fr

49、om sunlight.6.3.3 Maximum wind velocity.6.3.4 Possibility of abrasion caused by blowing sand or salt.6.3.5 Possible effect of high humidity or fog.6.4 Water Vapor Transmission (Vapor RetardingCapability)Consideration should be given to the ability of ajacketing material to inhibit transport of water vapor through it.Some factors to consider are the following:6.4.1 Water vapor tends to travel from areas of high vaporpressure to areas of low vapor pressure. See 9.2.1.6.4.2 Water in insulation tends to reduce its efficiency.Therefore, if the system constantly runs a
