E. Lettering:

1. Stencils or Markers: Contents identification labels and directional arrows shall be painted directly on piping using stencils.

2. Pipe identification markers shall be vinyl or polyester construction with an adhesive strip, coiled to wrap completely around the pipe (no straps) and have subsurface printing. Pipe less than 6 inches shall be have lettering to meet ASME A13.1 standard and shall be Marking Services Inc., MS-970 or MS-995; Accuform Subsurface Snaptite; Or Equal. Pipe 6 inches or larger shall have 2-inch lettering on a 12-inch field minimum and shall be Marking Services Inc., MS-995; Accuform Subsurface Snaptite; Or Equal.

3. The size of the letters for identification labels shall be as follows:

Pipe Outside Diameter* (inches)	Letter Size (inches high)
5/8 to 1-1/4	1/2
1-1/2 to 3	1
Over 3	2

*Outside pipe diameter shall include insulation and jacketing.

4. Identification markers shall have letters, directional arrows and colors as follows: Plant Water Black Letters on Yellow Field

2.2 IDENTIFICATION OF VALVES AND SHORT PIPE LENGTHS

A. Identifying devices for valves and the sections of pipe that are too short to be identified with lettered labels, and arrows shall be identified with engraved metal tags as specified in the OCSD Tagging Procedure standard and elsewhere in Division 16 and 17.

2.3 IDENTIFICATION OF PIPE 5/8-INCH OR SMALLER

A. Where the outside diameter of pipe or pipe covering is 5/8 inch or smaller, metal tags shall be provided instead of lettering. Tags shall have the specified identifying lettering stamped in the tag and shall be fastened to the pipe with suitable chains. Metal tags and chains shall be stainless steel. Where tags are used, pipe shall be color-coded as specified in Article entitled “Identification Schedule” herein.

2.4 REMNANTS OF ABANDONED PIPE

A. Remnants of buried abandoned pipe that extend into tunnels or are otherwise visible shall be identified at the point of emergence by original service, job number of original installation, and job number of demolition project.

B. The information shall be stenciled on the wall adjacent to the remaining penetration. Lettering shall be black, 1 inch high, and painted on a white background. If no adjacent surface is suitable for the lettering, an engraved metal tag shall be used.
