25、- 5 - CLC/TS 50430:2005 1 Scope This document is a family specification that covers gas pipe cables and sub-ducts for installation by blowing and/or pulling / dragging in high pressure gas pipes. Systems built with components covered by this standard are subject to the requirements of sectional spec
26、ifications EN 60794-3 and EN 60794-4 where applicable. Gas pipe cable and sub-duct constructions have to meet the different requirements of the gas- companies and/or associations regarding chemical, environmental, operational interactions and in general maintenance conditions. A table of preferentia
27、l applications, describing gas pipe cable characteristics versus methods of installation is reported in Annex A for high pressure gas pipe cables. Clause 4 describes a blank detail specification for gas pipe cables and sub-ducts for installation by blowing and/or pulling / dragging in/into high pres
28、sure gas pipes. It incorporates some minimum requirements. Detail specifications may be prepared on the basis of this family specification. The parameters specified in this standard may be affected by measurement uncertainty arising either from measurement errors or calibration errors due to lack of
29、 suitable standards. Acceptance criteria should be interpreted with respect to this consideration. The number of fibres tested is representative of the sewer cable and should be agreed between the customer and supplier. 2 Normative references The following referenced documents are indispensable for

The materials in the gas pipe cable and/or as well as accessories including fixing elements i.e. I/O-ports and sub-ducts shall not
43、 present a health hazard within its intended use. 4.1.2 Sub-ducts In case of use, the sub-duct with outer nominal diameters ranging from xx mm to yy mm shall be able to resist pressure differences needed for installation by blowing and able to withstand the gas pressure within the gas pipe. They sha
44、ll be circular and the outer and inner surfaces a low coefficient of friction. The material shall withstand all possible chemical attacks by the natural gas itself, as for instance the PE 100. Inner- and outer-diameter and overall minimum wall thickness shall be specified. 4.1.3 Gas pipe cables A ga
45、s pipe cable in accordance to this specification should be suitable for installation in high pressure gas pipes by the following installation methods, also applicable the access gas pipe network: blowing and /or pulling into a sub-duct, previously installed into the high pressure gas pipe between tw
46、o I/O - ports; direct installation into the gas pipe in between two adjacent I/O-ports. The attenuation of the installed cable at the operational wavelength(s) shall not exceed values agreed between the customer and supplier. There shall be no fibre splice in a delivery length unless otherwise agree
47、d by the customer and supplier. It shall be possible to identify each individual fibre throughout the length of the sewer cable.
