Significance and Use4.1 This practice is for use by designers and specifiers,regulatory agencies, owners, and inspection organizations whoare involved in the
21、 rehabilitation of pipes through the use of aresin-impregnated tube installed within a damaged existinghost pipe. As for any practice, modifications may be requiredfor specific job conditions.5. Materials5.1 Tube:5.1.1 The textile tube shall consist of one or more layers ofabsorbent textile, for exa
22、mple, needle punched felt or circularknit, fiberglass or similar textile materials that meet therequirements of Practice F1216 and the Requirements and TestMethods sections of Specification D5813. The tube shall beconstructed to withstand installation pressures and to havesufficient strength to brid
23、ge missing pipe segments and flex-ibility to fit irregular pipe sections. The wet-out tube shall meetthe Resin Impregnation Requirements of Practice F1216, andshall have a uniform thickness with excess resin distributionthat when compressed at installation will meet or exceed thedesign thickness aft
24、er cure.5.1.2 The tube shall be surrounded by an impermeableflexible translucent bladder that will contain the resin andfacilitate visual monitoring of the vacuum impregnation (wet-out) procedure.5.1.3 The tube shall be continuous. No intermediate orencapsulated elastomeric layers shall be in the te
25、xtile that maycause delamination in the finished cured-in-place pipe. Thetube shall be sized accordingly to create a circular lining equalto the inside of the host pipe.5.1.4 The tube shall be fabricated with a 2 in. (5.1 cm) ringof compressible textile material at the upstream and down-stream ends,
26、 to create a smooth transition. The compressibletextile material will compress to meet the host pipe at itsleading end and match the nominal thickness of the tube at itsopposite end.5.1.5 The tube shall be fabricated to include a hydrophilicneoprene rubber O-ring at each end of the tube. The O-rings
27、hall be attached to the inner side of the liner tube prior to resinimpregnation.5.2 Resin:5.2.1 The resin/liner system shall conform to the TestMethods section of Specification D5813- 10,000-hour test andthe Test Method D3681 using a 10,000 hour test period.5.2.2 The resin shall be a corrosion resis
28、tant polyester, vinylester, epoxy resin, or silicate and catalyst system that whenproperly cured within the composite liner assembly, meets therequirements of Practice F1216, the physical properties herein,and those, which are to be utilized in the design of the SCIPLfor this project.5.2.3 The resin
29、 shall produce a SCIPL, which will complywith the structural and chemical resistance requirements ofPractice F1216.6. Design Considerations6.1 The SCIPL shall be designed in accordance with Prac-tice F1216, Appendix X1, Section X1.1.2.6.2 The SCIPLdesign for the sectional liner shall assume nobondin
30、g to the original host pipe.7. Installation Recommendations7.1 Access SafetyPrior to entering access areas such asmanholes or excavation pits, performing inspection, or clean-ing operations, an evaluation of the atmosphere shall beconducted to determine the presence of toxic or flammablevapors or la
31、ck of oxygen in accordance with local, state, orfederal safety regulations.7.1.1 Cleaning and Inspectionin accordance withNASSCO Guidelines.7.1.2 Inspection of PipelinesThe interior of the pipelineshall be carefully inspected to determine the location of anycondition that shall prevent proper instal
32、lation, such as rootsand collapsed or crushed pipe. These conditions shall be notedso that they can be corrected before installation of the SCIPL.Experienced personnel trained in locating breaks, obstacles,and service connections by closed circuit television shallperform inspection of pipelines.7.1.
33、3 Line ObstructionsThe existing host pipe shall beclear of obstructions that prevent the proper insertion andF2599 162expansion of the lining system. Changes in pipe size shall beaccommodated according to the pipe diameter and condition.Obstructions may include dropped or offset joints of more than2
34、0 % of the inside pipe diameter.7.2 Resin ImpregnationThe tube encapsulated within thetranslucent bladder (liner/bladder assembly) shall be vacuum-impregnated with resin (wet-out) under controlled conditions.The volume of resin used shall be sufficient to fill all voids inthe tube material at nomina
35、l 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 the cracks and joints of the host pipe.No dry or unsaturated area in the main tube shall be acceptableupon visual inspection.7.
36、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,protecting the tube from resin loss. The launcher is insertedinto the host pipe and towed to the beginning of the damagedsection
37、.After positioning, pressurized air is introduced causingthe liner/bladder assembly to project out of the launchersimultaneously inverting and inflating the resin-impregnatedtube against the host pipe. When fully inverted, the tube iscontinuous in length covering the damaged section and extend-ing a
38、 minimum of 18 in. (45.7 cm) on each side of the damagedsection of the host pipe, with the hydrophilic O-rings posi-tioned between the liner tube and the host pipe.7.4 CuringAfter the liner tube placement is completed;pressure is maintained, pressing the liner firmly against thehost pipes inner wall
39、. The liner is cured at ambient tempera-tures or by a suitable heat source. The heating equipment shallbe capable of delivering a mixture of steam and air throughoutthe liner/bladder assembly to uniformly raise the temperatureabove the temperature required to cure the resin. The curing ofthe SCIPL s
40、hall take into account the existing host pipematerial, the resin system, and ground conditions (temperature,moisture level, and thermal conductivity of the soil). Thetemperature shall be monitored and logged during the cure andcool down cycles.7.5 Curing ProcessingCuring shall be done without pres-s
41、ure interruption with air or a mixture of air and steam for theproper duration of time in accordance with the resin manufac-turers recommendations. When the heat source is removed andthe temperature of the SCIPL reaches 100F (37.8C) or less,the processing shall be finished. For an ambient cured meth
42、od,a coupon suspended in the manhole will determine curing time.7.6 Bladder RemovalA visual inspection during bladderremoval will verify the completion of the cure.8. Finish8.1 The finished SCIPL shall be continuous over the entirelength of the rehabilitated section of the pipe. The SCIPL shallbe fr
43、ee of dry spots, lifts, and delamination. The cured linershall taper at each end so as to accept video equipment andmaintain a proper flow. The hydrophilic O-ring shall bepositioned between the liner tube and the host pipe producinga compression gasket seal that is compatible with all pipingmaterial
44、s. After the work is completed, the installer willprovide the owner with video footage documenting the com-pleted work, in accordance with NASSCO Guidelines.9. Recommended Inspection Practices9.1 SamplingAs designated by the purchaser in the pur-chase agreement, the preparation of a SCIPL sample is
45、re-quired. The sample shall be of the same textile tube materialand resin system as used for the rehabilitated pipe.9.1.1 The minimum length of the sample must be able toproduce at least five specimens for testing in accordance withTest Method D790.9.2 Short-Term Flexural (Bending) PropertiesThe ini
46、tialtangent flexural modulus of elasticity and flexural strengthshall be measured for gravity pipe applications in accordancewith Test Method D790 and shall meet the minimum require-ments of Table 1.10.
