Significance and Use4.1 This practice is for use by designers and specifiers,regulatory agencies, owners, and inspection organizations whoare involved in the rehabilitation of pipes through the use of aresin-impregnated tube installed within a damaged existingpipe. As for any practice, m
20、odifications may be required forspecific job conditions.5. Materials5.1 Tube5.1.1 The textile tube shall consist of one or more layers ofabsorbent textile, for example, needle punched felt or circularknit, fiberglass or similar textile materials that meet therequirements of Practice F 1216 and Requi
21、rements and TestMethods sections of Specification D 5813. The tube shall beconstructed to withstand installation pressures, have sufficientstrength to bridge missing pipe segments, and flexibility to fitirregular pipe sections. The wetout tube shall meet ResinImpregnation Requirements of Practice F
22、1216, and shall havea uniform thickness and with excess resin distribution thatwhen compressed at installation will meet or exceed the designthickness after cure.5.1.2 The tube shall be surrounded by an impermeableflexible translucent bladder that will contain the resin andfacilitate visual monitori
23、ng of the vacuum impregnation(wetout) procedure.5.1.3 The tube shall be continuous. No intermediate orencapsulated elastomeric layers shall be in the textile that maycause de-lamination in the finished cured in place pipe. Thetube shall be sized accordingly to create a circular lining equalto the in
24、side of the main pipe.5.1.4 The tube shall be fabricated with a 2 inch ring ofcompressible textile material at the upstream and downstreamends, to create a smooth transition. The compressible textilematerial will compress to meet the host pipe at its leading endand match the wall thickness of the tu
25、be at its opposite end.5.2 Resin5.2.1 The resin/liner system shall conform to Test Methodssection of Specification 5813- 10,000-hour test and TestMethod D 3681 using a 10,000 hour test period.5.2.2 The resin shall be a corrosion resistant polyester, vinylester, epoxy resin, or silicate and catalyst
26、system that whenproperly cured within the composite liner assembly, meets therequirements of Practice F 1216, the physical properties herein,and those, which are to be utilized in the design of the SCIPLfor this project.5.2.3 The resin shall produce a SCIPL, which will complywith the structural and
27、chemical resistance requirements ofPractice F 1216.6. Design Considerations6.1 The SCIPL shall be designed per Practice F 1216,Appendix X1, Section X1.1.2.6.2 The SCIPLdesign for the sectional liner shall assume nobonding to the original pipe.7. Installation Recommendations7.1 Access SafetyPrior to
28、entering access areas such asmanholes or excavation pits, perform inspection or cleaningoperations, an evaluation of the atmosphere shall be conductedto determine the presence of toxic or flammable vapors or lackof oxygen in accordance with local, state, or federal safetyregulations.7.1.1 Cleaning a
29、nd Inspection as per NASSCO Guidelines.7.1.2 Inspection of PipelinesThe interior of the pipelineshall be carefully inspected to determine the location of anycondition that shall prevent proper installation, such as roots,and collapsed or crushed pipe. These conditions shall be noted.Experienced pers
30、onnel trained in locating breaks, obstacles,and service connections by closed circuit television shallperform inspection of pipelines.7.1.3 Line ObstructionsThe existing host pipe shall beclear of obstructions that prevent the proper insertion andexpansion of the lining system. Changes in pipe size
31、shall beaccommodated according to the pipe diameter and condition.Obstructions may include dropped or offset joints of more than20 % of inside pipe diameter.7.2 Resin ImpregnationThe tube encapsulated within thetranslucent bladder (liner/bladder assembly) shall be vacuum-impregnated with resin (wet-
32、out) under controlled conditions.The volume of resin used shall be sufficient to fill all voids inthe tube material at nominal thickness and diameter. Thevolume shall be adjusted by adding excess resin for the changein resin volume due to polymerization and to allow for anymigration of resin into th
33、e cracks and joints in the original pipe.No dry or unsaturated area in the main tube shall be acceptableupon visual inspection.7.3 Liner InsertionThe bladder and tube (liner/bladderassembly) is drawn inside the launcher through the open end.The liner/bladder assembly is contained within the launcher
34、,protecting the tube from resin loss. The launcher is insertedinto the pipe and towed to the beginning of the damagedsection. When positioned, pressurized air is introduced causingthe liner/bladder assembly to project out of the launchersimultaneously inverting and inflating the resin impregnatedtub
35、e against the host pipe. When fully inverted, the tube iscontinuous in length covering the damaged section and extendsa minium of 189 on each side of the damaged section of thehost pipe.7.4 CuringAfter liner placement is completed; pressure ismaintained pressing the liner firmly against the inner pi
36、pe wall.The liner is cured at ambient temperatures or by a suitable heatsource. The heating equipment shall be capable of delivering amixture of steam and air throughout the liner bladder assemblyto uniformly raise the temperature above the temperatureF2599062required to cure the resin. The curing o
37、f the SCIPL shall takeinto account the existing pipe material, the resin system, andground conditions (temperature, moisture level, and thermalconductivity of the soil). The temperature shall be monitoredand logged during the cure and cool down cycles.7.5 Curing ProcessingCuring shall be done withou
38、t pres-sure interruption with air or a mixture of air and steam for theproper duration of time per the resin manufacturers recom-mendations. When the heat source is removed and the tem-perature of the SCIPL reaches 100 degrees F or less, theprocessing shall be finished. For an ambient cured method,
39、acoupon suspended in the manhole will determine curing time.7.6 Bladder RemovalA visual inspection during bladderremoval will verify the completion cure.8. Finish8.1 The finished SCIPL shall be continuous over the entirelength of the rehabilitated section of pipe. The SCIPL shall befree of dry spots
40、, lifts, and delamination. The cured liner shalltaper at each end so as to accept video equipment and maintaina proper flow. After the work is completed, the installer willprovide the owner with video footage documenting the com-pleted work, as per NASSCO Guidelines.9. Recommended Inspection Practic
41、es9.1 SamplingAs designated by the purchaser in the pur-chase agreement, the preparation of a SCIPL sample is re-quired. The sample shall be the same textile tube material andresin system as used for the rehabilitated pipe.9.1.1 The minimum length of the sample must be able toproduce at least five s
