1、Designation: F 2019 03An American National StandardStandard Practice forRehabilitation of Existing Pipelines and Conduits by thePulled in Place Installation of Glass Reinforced Plastic(GRP) Cured-in-Place Thermosetting Resin Pipe (CIPP)1This standard is issued under the fixed designation F 2019; the

2、 number immediately following 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 (e) indicates an editorial change since the last revision or reapproval.1.

3、Scope1.1 This practice covers the procedures for the reconstruc-tion of pipelines and conduits (4 to 48 in. (100 to 1200 mm)diameter) by the pulled-in place installation of a resin-impregnated, flexible fabric tube into an existing conduitfollowed by inflation with compressed air (see Fig. 1). There

4、sin/fabric tube can be cured by either the flow through thefabric tube of mixed air and steam or by use of ultraviolet light.When cured, the finished cured-in-place pipe will be continu-ous and tight fitting. This reconstruction process can be used ina variety of gravity flow applications such as sa

5、nitary sewers,storm sewers, process piping, electrical conduits, ventilationsystems, and pressure applications.1.2 The values stated in inch-pound units are to be regardedas the standard. The values given in parentheses are forinformational purposes only.1.3 This standard does not purport to address

6、 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 of regulatory limitations prior to use.2.

Gravity pipes shall becleaned with hydraulically powered equipment, high velocityjet cleaners, or mechanically powered

31、 equipment in accordancewith NASSCO Recommended Specifications for Sewer Col-lection System Rehabilitation. Pressure pipelines shall becleaned with cable attached devices or fluid propelled devicesin accordance with AWWA Manual on Cleaning and LiningWater Mains, M28.6.1.3 Line ObstructionsThe origin

32、al pipeline should beclear of obstructions such as solids, dropped joints, protrudingservice connections, collapsed pipe, and reductions in thecross-sectional area of more than 40 % that may hinder orprevent the installation of the resin impregnated fabric tube.Where the inspection reveals an obstru

33、ction that cannot beremoved by conventional sewer cleaning equipment, then apoint repair shall be made to remove the obstruction.6.1.4 Inspection of PipelinesInspection of pipelines shallbe performed by experienced personnel trained in locatingbreaks, obstacles and service connections by closed circ

34、uittelevision or man entry. The interior of the pipeline shall becarefully inspected to determine the location of any conditionsthat prevent proper installation of the impregnated tube, suchas protruding service taps, collapsed or crushed pipe, andreductions in the cross-sectional area of more than

35、40 %. Theseconditions shall be noted and corrected prior to the installation.6.1.5 Pre-Measurement of Service Connections:6.1.5.1 A pre-measuring of all service locations shall beperformed by experienced personnel. Due to the reinforcementof the fabric tube visible indentations by the lateral connec

36、tionsmay not be readily identified.6.1.5.2 The measurements shall be noted in a log alsocontaining information about the clockwise position of theopening.6.1.6 Bypassing:6.1.6.1 Where bypassing the flow is required around thesections of pipe designated for reconstruction, the bypass shallbe made by

37、plugging the line at the up-stream end of the pipeto be reconstructed and pumping the flow to a downstreampoint or adjacent system.6.1.6.2 The pump and bypass lines shall be of adequatecapacity and size to handle the flow. Services within the reachshall be temporarily out of service.6.1.7 Public adv
