2、he 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. Scope*1.1 This practice covers t

3、he procedures for the reconstruc-tion of pipelines and conduits (4 to 60 in. (100 to 1500 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). Theresin/fabric tube can be cured by

4、 either the flow through thefabric tube of mixed air and steam or hot water or by use ofultraviolet light. When cured, the finished cured-in-place pipewill be continuous and tight fitting. This reconstruction processcan be used in a variety of gravity flow applications such assanitary sewers, storm

24、Where a removable calibration hose is used, the internalsurface shall consist of a resin rich layer for high chemical andabrasion resistance. The fabric tube shall further be constructedwith longitudinal unidirectional glass roving of sufficientstrength to negotiate a pulling force at least equal to

25、 the weightof the liner. The fabric tube shall tolerate circumferentialchanges in the existing conduit. In order to allow a close fitinstallation in deformed host pipes, as well as to avoid wrinklesin the final CIPPproduct, the fabric tube shall be produced withan under measurement of at least 1 % o

26、f the host pipesnominal diameter, and the ability to be over-expanded by atleast 1 % of the host pipes nominal diameter. The ability toover-expand is essential to avoid annular spaces or cavitiesbetween the host pipe and the liner and thereby to guarantee theconditions assumed in the static calculat

Where theinspection reveals an obstruction that cannot be removed byconventional sewer cleaning equipment, then a robot

38、 with acutter or other suitable tool should be used to remove theobstruction.6.1.4 Inspection of PipelinesInspection of pipelines shallbe performed by experienced personnel trained in locatingbreaks, obstacles and service connections by closed circuittelevision or man entry. The interior of the pipe
