In recent years, the number of different types of pipe materials is increasing, plus there are lined pipes with various liner materials. </P><P>Do you label the host pipe material AND the liner material? Do you identify if it is a 'burst' pipe? Do you differentiate smooth pipe vs. ribbed pipe. For example,various spirals and profiles exist and many are not compatible in terms of fittings, etc. which becomes problematic for field crews doing emergency repairs.</P><P>Labeling everything makes for a cluttered map; however, relying on asbuilt drawings for everything has its own issues.</P><P>FredThu, 01 May 2008 16:21:22 GMTFred S.
