What Do the Different Colors of PVC Pipe Mean?

 The color of PVC (polyvinyl chloride) pipe is used to denote its intended purpose or application. While the color codes can vary slightly between regions or manufacturers, there are some common color codes for PVC pipes:

White PVC Pipe: White PVC pipes are often used for plumbing and potable water applications. They are suitable for carrying cold water and are also used for drainage and vent systems in residential and commercial buildings.

Gray PVC Pipe: Gray PVC pipes are typically used for drainage, sewage, and other non-pressure applications. They are commonly used in underground applications where the pipe is not exposed to sunlight.

Green PVC Pipe: Green PVC pipes are used for sewer lines and wastewater applications. They are specifically designed for underground use and are resistant to corrosion and chemicals commonly found in sewage.

Blue PVC Pipe: Blue PVC pipes are used for carrying potable (drinkable) water. They are often used in municipal water supply systems, water treatment plants, and other applications where safe drinking water is a priority.

Yellow PVC Pipe: Yellow PVC pipes are used for natural gas lines. They are marked with a yellow color to indicate that they are intended for carrying natural gas. Yellow PVC pipes are designed to be resistant to the chemicals found in natural gas.

Orange PVC Pipe: Orange PVC pipes are used for electrical conduits. They are designed to protect electrical wires and cables in underground or exposed applications. The orange color helps identify them as electrical conduits.

It's important to note that these color codes are not universal, and there might be variations based on local regulations or specific manufacturer guidelines. Therefore, it's always advisable to check with the supplier or refer to local codes and standards to confirm the intended use of PVC pipes based on their color.
