1、Designation: F2718 09 (Reapproved 2015)Standard 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 F2718; the number immediately fol
2、lowing the designation 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 specificat
3、ion covers requirements 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
4、, folded at the 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 surfa
5、ce of the original 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

It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the
7、 applica-bility of regulatory limitations prior to use.1.5 There is no similar or equivalent ISO standard.2.

17、 M28 “Structural Lining Design Issues,” contains a more detaileddiscussion of structural classification 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
18、of the host pipe,all internal pressure loads are transferred to the host pipeleading to their classification 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
19、 subject to structural failure.”4. Materials4.1 Basic Materials:4.1.1 PE MaterialsThe liner and the 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.
20、 The cementmortar shall have the minimum physical properties as in Table2.5. Sampling5.1 Cement mortar: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 mo
21、rtar component of the formed-in-placeliner system (FIPLS) shall have a 28 d compressive strength of7000 psi (48.2 MPa) as tested by Test Method C109/C109M.6.2 WorkmanshipThe PE liner shall be essentially uniformin color and opacity. There shall be no evidence of splits,cracks, crazing, or breaks.7.
22、Inspection7.1 Inspection of the materials shall be made as agreed uponby the purchaser and the seller as part of the purchaseagreement.FIG. 1 PE and Encapsulated Cement Mortar Formed-In-Place-Liner System (FIPLS)F2718 09 (2015)28.
