ASTM WK24075

    Work Item: ASTM WK24075 - New Specification for High-Density Polyethylene (HDPE) Profile Strip for Machine Spiral Wound Liner Pipe Rehabilitation of Existing Sewers and Conduit

    (What is a Work Item?)

    Developed by Subcommittee: F17.67 | Committee F17 | Contact Staff Manager



    1. Scope

    1.1 This specification covers requirements and test methods for materials, dimensions, workmanship, extrusion quality, and a form of marking for high-density polyethylene (HDPE) profile strips used for machine-made field fabrication of spirally wound pipe liners in the rehabilitation of a variety of gravity applications such as sanitary sewers, storm sewers, and process piping in diameters of 36 to 120 in. 1.2 Profile strip produced to this specification is for use in field fabrication of spirally wound liner pipes in nonpressure sewer and conduit rehabilitation in which the spirally wound liner pipe is inserted as a fixed diameter into the existing sewer or conduit and the annular space between the liner pipe and the existing sewer or conduit is grouted. 1.3 This specification includes extruded profile strips made only from materials specified in Section 5, Materials and Manufacture, Paragraph 5.1, Polyethylene Materials. 1.4 The values in inch-pound units are to be regarded as the standard. The values in parentheses are provided for information only. 1.5 The following precautionary caveat pertains only to the test method portion, Section 11, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

    There is presently no standard specification covering rehabilitation with this product. Such a standard is required by municipal water authorities and similar groups to specify properly the products available.
