This 2in. x 14in. Self-Adhesive Domestic Cold Water Decal provides a reliable and clear way to label domestic cold water pipes. When installing a plumbing system, standards from the American National Standards Institute (ANSI) and the American Society of Mechanical Engineers (ANSI) recommend that all piping to be labeled according to:
- The type of piping system
- The contents of the pipes
- The direction in which the contents of the pipes flow
These 2in. x 14in. self-adhesive sprinkler pipe markers feature 1-1/4 'DOMESTIC COLD WATER' lettering over a 14in. green background. The decals are constructed using glossy vinyl film, will withstand temperatures between -40F (4C) and 180F (82C), and are ideal for use on 2-1/2in. to 7-7/8in. pipes.
Where do I place these pipe markers?
The 2in. x 14in. Self-Adhesive 'DOMESTIC COLD WATER' Decals tell technicians, firefighters, inspectors, and anyone working with the piping system that it contains cold water for use in plumbing applications. However, they do not include arrows to communicate the direction of water flow.
2in. x 14in. Self-Adhesive 'DOMESTIC COLD WATER' Decals should be installed on pipes between 2-1/2in. and 7-7/8in. in size at locations such as:
- Near valves and flanges
- Where a pipe changes direction (wherever elbows are used)
- On both sides of ceiling, wall, or floor penetrations
- At any line entry or re-entry point
- Every 25-50 on straight pipe runs
Are Kolbi pipe markers right for my piping system?
Piping labels that use white markings on green backgrounds are reserved for piping systems that carry materials of low hazard not meant for fire sprinklers or fire-fighting. These Style C Kolbi labels will fit pipes with an outer diameter between 2-1/2in. and 7-7/8in..
Note that a pipe's outside diameter is always larger than the pipe's nominal size or trade name.The outer diameter of a pipe may be a quarter-inch, half-inch, or three-quarters of an inch larger than the nominal size (or larger, if insulating materials are installed on the pipe's exterior).
After the label is applied the piping system cannot drop below -40F (4C), or rise above 180F (82C), or the labels may fall off. During application, the piping system must be clean, dry, and cannot measure above 50F (10C).
How do I apply these decals to my pipe?
Follow these steps to stick Kolbi pipe markers on domestic cold water pipes:
- Be sure that the surface of the pipe is clean, dry, and measures at or above50F (10C) before applying the label
- Determine the normal point of approach, the angle the decal will likely be viewed from
- Remove the back film
- Place the decal over the pipe and rub it until securely attached
