2.02 MECHANICAL IDENTIFICATION MATERIALS:
A. General: Provide manufacturer's standard products of categories and types required for each
application as referenced in Division 21, 22 and 23 sections. Where more than single type is
specified for application, selection is Installer's option but provide single selection for each
product category.
2.03 PLASTIC PIPE MARKERS:
A. Snap-On Type: Provide manufacturer's standard pre-printed, semi-rigid snap-on, color-coded
pipe markers, complying with ANSI A13.1.
B. Insulation: Furnish 1" thick molded fiberglass insulation with jacket for each plastic pipe
marker to be installed on uninsulated pipes subjected to fluid temperatures of 125° F or
greater. Cut length to extend 2" beyond each end of plastic pipe marker.
C. Small Pipes: For external diameters less than 6" (including insulation if any), provide full-band
pipe markers, extending 360 degrees around pipe at each location, fastened by one of the
following methods:
1. Snap-on application of pre-tensioned semi-rigid plastic pipe marker.
2. Adhesive lap joint in pipe marker overlap.
3. Laminated or bonded application of pipe marker to pipe (or insulation).
4. Taped to pipe (or insulation) with color-coded plastic adhesive tape, not less than 1-
1/2’’ wide; full circle at both ends of pipe marker, tape lapped 3’’.
D. Large Pipes: For external diameters of 6" and larger (including insulation if any), provide
either full-band or strip-type pipe markers, but not narrower than 3 times letter height (and of
required length), fastened by one of the following methods:

1. Laminated or bonded application of pipe marker to pipe (or insulation).
2. Taped to pipe (or insulation) with color-coded plastic adhesive tape, not less than 1-
1/2’’wide; full circle at both ends of pipe marker, tape lapped 3’’.
3. Strapped-to-pipe (or insulation) application of semi-rigid type, with manufacturer’s
standard stainless steel bands.
E. Lettering: Manufacturer’s standard pre-printed nomenclature which best describes piping
system in each instance, as selected by Engineer in cases of variance with name as shown or
specified.
F. Lettering: Comply with piping system nomenclature as specified, scheduled or shown, and
abbreviate only as necessary for each application length.
G. Arrows: Print each pipe marker with arrows indicating direction of flow, either integrally with
piping system service lettering (to accommodate both directions), or as separate unit of plastic.
2.04 PLASTIC TAPE:
A. General: Provide manufacturer's standard color-coded pressure- sensitive (self-adhesive)
vinyl tape, not less than 3 mils thick.
B. Width: Provide 1-1/2" wide tape markers on pipes with outside diameters (including insulation,
if any) of less than 6", 2-1/2" wide tape for larger pipes.
C. Color: Comply with ANSI A13.1, except where another color selection is indicated.
2.05 PLASTICIZED TAGS:

A. Coordination: Where identification is to be applied to surfaces which require insulation,
painting, or other covering or finish, including valve tags in finished mechanical spaces; install
identification after completion of covering and painting. Install identification prior to installation
of acoustical ceilings and similar removable concealment.
3.02 PIPING SYSTEM IDENTIFICATION:
A. General: Install plastic pipe markers, with application system as indicated under "Materials" in
this section.
1. Include arrows to show normal direction of flow.
2. Install on pipe insulation segment where required for hot non-insulated pipes.
B. Locate pipe markers and color bands as follows wherever piping is exposed to view in
occupied spaces, machine rooms, accessible maintenance spaces (shafts, tunnels, plenums)
and exterior non-concealed locations.
