There-fore, it is important to reduce the exposure of such insulatingmaterials to water-soluble

Once the manufacture is complete, caremust be exercised dur

Thispractice presents criteria which, if followed, will minimize therisks of ESCC assoc

It should be emphasized, however, that because ofthe many variable factors present, complete freedom fromESCC can not be assured under all circumstances, even whenfollowing the guidance of this practice.4.2 Continued protection of the insulation and

General5.1 Only materials that have been tested and qualified (seeNote 1) should be used as a surface treatment or as a part of thethermal insulation system applied to austenitic stainless steel.Requirements for preproduction or qualification testi
19、ng andsubsequent lot testing by the manufacturer or seller shall bespecified by the purchaser when ordering.NOTE 1For example, thermal insulation shall be tested in conform-ance to Specification C 795 using Test Method C 692 and Test MethodC 871.5.2 Where possible, qualified and unqualified material
20、sshould be kept physically segregated. Where conditions makeit necessary to have both qualified and unqualified materials ofthe same type at the job site, storage area, or in the sameshipment, all qualified materials should be clearly identifiablefrom unqualified materials. The need for special iden
21、tificationshould be specified by the purchaser when ordering.6. Handling, Transporting, and Shipping6.1 All handling and transporting of materials should bedone in a manner that will prevent contamination from externalsources.6.2 Shipment of materials from the manufacturer to theinstallation locatio
22、n of the user should be in weathertighttransportation. Provisions and responsibility for special trans-portation or packaging should be agreed upon between thepurchaser and the seller or manufacturer.7. Storage7.1 All insulation shall be stored in a manner that willprevent contamination from externa
23、l sources.7.2 All insulation and accessory materials should be storedin weathertight buildings. Storage buildings should be situatedand constructed so that they will not be subject to flooding. Thefloor should be paved, or equal, and welldrained.7.3 Insulation shall be placed on pallets or shoring t
24、oprevent direction contact with the ground or floor.7.4 If qualified and unqualified materials are stored in thesame area, they should be segregated.8. Inspection8.1 Insulation and accessory materials should be inspectedat various stages prior to application to further reduce the riskof contaminatio
25、n. Retesting may be desirable in a particularlycritical application such as pressure vessels, or when contami-nation is suspected by visual examination.8.1.1 External shipping containers, packages, or cartonsshould be visually inspected for evidence of water damage orcontamination when received at t
26、he jobsite, when removedfrom storage, and just prior to application. Any containersshowing evidence of water damage or contamination shouldnot be used. They should be clearly marked and set aside forfurther inspection, testing, disposal, or used as unqualifiedmaterial.8.1.2 Documentation shall be su

Application Precautions9.1 Although this practice will help to prevent stress corro-sion cracking of austenitic stainless steel surfaces, it should benoted that the cleanliness of the surface to which it is appliedi

Stainless steel surfaces may be con-taminated from external sources, such as airborne sea mistcarried by onshore winds, chemical fumes, ink from markingpens, adhesive on tape, accidental spills of watersolublechloride ion-bearing materials, melting salts used to clear iceand s
29、now, and many other ways. The contaminant should beremoved from the surface before insulation is applied andprecautions should be taken to prevent their entrance duringand after the installation.9.2 Any material suspected of being contaminated duringthe application should not be used and should be c
30、learlymarked and set aside for further testing, disposal, or used asunqualified material.9.3 When insulating cements are to be in contact withaustenitic stainless steel surfaces, they shall be mixed withdistilled or demineralized water.9.4 Mixing containers and tools must be thoroughly cleanedand dr
31、ied prior to use so as not to increase the chloride ioncontent of the material . Used containers, such as mortar boxesor empty paint or mastic pails, shall not be used as mixingcontainers.10. Material Control Procedures10.1 Specific material control procedures consistent withthis practice should be
32、agreed upon between the purchaser andthe manufacturer or seller and the applicator as part of thepurchase contracts. The procedures shall include the following:10.1.1 PackagingPackaging shall assure adequate protec-tion for transportation, handling, and storage on the jobsite. Ifother than manufactu
33、rers (sellers) standard packaging for thistype of material, it is required it shall be so stated in thepurchase order.10.1.2 MarkingMarking shall be as specified or as agreedupon between the purchaser and the supplier.10.1.3 Inspection and TestingAny requirements for quali-fication, inspection, or t
34、esting should be specified. Provisionsshould be made for certification or submittal of test reports, ifrequired.10.1.4 Transportation and HandlingResponsibility fortransportation of material at each stage should be established.The method of transportation and vehicle requirements shouldbe agreed upo
35、n and specified.10.1.5 StorageResponsibility for providing adequate stor-age at each stage should be established and specific spacerequirements should be determined. Specific provisions forsegregating qualified and unqualified materials should bespecified.10.1.6 Rejected MaterialSpecific procedures
36、should beestablished for marking and segregating materials suspected ofcontamination. Provisions for testing, rejecting, and disposal ofthese materials should be specified.C 929 94 (2009)211.
