Did you know that excavation efforts in the United States are causing an underground cable to be destroyed every three minutes? The National Utility Notification Hotline (811) provides this disturbing information. It emphasizes the crucial significance of exercising caution before commencing any excavation activity. In this blog post we are going to learn about importance of high density polyethylene pipe color codes.
Gas, water, and electrical lines are often buried slightly beneath the surface, out of sight. Digging without first assessing what’s beneath the earth may be both costly and dangerous. However, precautions are in place to prevent mishaps, such as labeling the surface and color-coding subterranean pipelines. These precautions assist workers understand what is present and where before they begin excavating. APWA Uniform Color Code.
The American Public Works Association (APWA) Uniform Color Code is the most reliable reference to recognizing the colors of underground high-density polyethylene (HDPE) pipes. This uniform code establishes solid and striped colors for subterranean pipes, allowing construction teams, excavators, and utility providers to immediately identify the type of pipe discovered during an excavation.
Different hues or tones can also be used to identify pipeline owners. For example, in the telecommunications business, numerous owners often have pipes in the same subsurface location. Using a color system reduces confusion and ensures that stakeholders understand who controls each pipeline.
Here is a color guide for HDPE pipe based on the APWA code:
The Plastic Pipe Institute (PPI) likewise adopts the APWA color code, which promotes industry standardization and safety. PPI strongly advises that the color yellow be used solely for gas distribution pipes, ensuring that these lines are immediately visible in the field. For further information, seethe PE Handbook of PE Pipe, Chapter 14 on Pipe and Conduit, Section 6.2, and APWA Uniform Color Code.
HDPE is made from tiny, colorless resin pellets, and color is added throughout the production process. Carbon black additives are used to protect against UV rays, as colored pipes fade when exposed to sunshine. ASTM F2160 requires that stabilizers used on colored conduit protect it for one year of outdoor storage. Even with UV stabilizers, colorful tubing can fade over time, thus black tubing is suggested for applications that need extensive exposure to sunlight.
