1、Designation: F 2718 09Standard Specification forPolyethylene (PE) and Cement Materials for anEncapsulated Cement Mortar Formed in Place Liner System(FIPLS) for the Rehabilitation of Water Pipelines1This standard is issued under the fixed designation F 2718; the number immediately following the desig
2、nation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers requi
3、rements and test methodsfor materials for a semi-structural polyethylene (PE) encapsu-lated cement mortar formed-in-place liner system (FIPLS)intended for the rehabilitation of water pipelines of nominalsize 4 in. to 12 in. This renewal process involves installing acollapsed PE liner, folded at the
4、time of insertion, into anexisting pipeline, expanding the PE liner, and then pumpingcement mortar into the annulus between the liner and the main.1.2 The liner and cement mortar are progressively roundedby means of an air pressure propelled pig and expanded againstthe interior surface of the origin
5、al host pipe.After rounding, theline is maintained under pressure until the cement mortar curesand the liner is completely self supporting.1.3 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provide
6、d for information onlyand are not considered standard.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility
7、of regulatory limitations prior to use.1.5 There is no similar or equivalent ISO standard.2.

16、and gaps and seal leaking joints in the host pipe andhaving sufficient inherent stiffness to be self supporting withoutdependence on adhesion to the pipe wall.3.3.1 DiscussionAppendix A of AWWA Manual M28 “Structural Lining Design Issues,” contains a more detaileddiscussion of structural classificat
17、ion of lining techniques. Thefollowing is taken from Manual M28: “Class II and Class IIILinings are both interactive and semi-structural systems. Sincethe stiffness of such a lining is less than that of the host pipe,all internal pressure loads are transferred to the host pipeleading to their classi
18、fication as interactive. Such a lining isrequired only to independently sustain internal pressure loadsat discontinuities in the host pipe, such as corrosion holes orjoint gaps, or if the host pipe is subject to structural failure.”4. Materials4.1 Basic Materials:4.1.1 PE MaterialsThe liner and the
19、hooks shall be madefrom PE material meeting the minimum physical properties aslisted in Table 1.4.1.2 The cement mortar is used to fill the ring cavitybetween the polyethylene liner and the host pipe. The cementmortar shall have the minimum physical properties as in Table2.5. Sampling5.1 Cement mort
20、ar:5.1.1 Samples will be taken of the cement mortar materialand tested throughout the installation process to confirm itscompliance to the properties listed in Table 2.6. Requirements6.1 The cement mortar component of the formed-in-placeliner system (FIPLS) shall have a 28 d compressive strength of7
21、 000 psi (48.2 MPa) as tested by Test Method C 109/C 109M.6.2 WorkmanshipThe PE liner shall be essentially uni-form in color and opacity. There shall be no evidence of splits,cracks, crazing, or breaks.7. Inspection7.1 Inspection of the materials shall be made as agreed uponby the purchaser and the
22、seller as part of the purchaseagreement.8. Rejection and Rehearing8.1 If the results of any test do not meet the requirements ofthis specification, these test(s) may be conducted again inaccordance with an agreement between the purchaser and theseller. There shall be no agreement to lower the minimu
23、mrequirement of the specification by such means as omittingtests that are a part of the specification, submitting or modify-ing a test method, or by changing the specification limits. Inretesting, the product requirements of this specification shall bemet and the test methods designated in the speci
24、fication shallbe followed. If, upon retest, failure occurs, the quantity ofproduct represented by the testing does not meet the require-ments of this specification.9. Quality Assurance9.1 When the product is marked with this designation,ASTM F 2718, the manufacturer affirms that the product wasmanuf
