Why are PPR pipes used in different colors?

PPR pipes are available in different colors primarily for identification and differentiation purposes. The use of different colors helps in easily distinguishing between different types of pipes and their designated applications. Here are some reasons why PPR pipes are used in different colors:

Differentiating between hot and cold water: In plumbing systems, it is essential to differentiate between pipes carrying hot water and those carrying cold water. Using different colors for PPR pipes helps in visually distinguishing between the two. For example, blue color is often used for cold water pipes, while red or orange color is used for hot water pipes.

System identification: PPR pipes of different colors can be used to identify specific systems within a building. For instance, a specific color may be used for pipes supplying water to a particular floor, room, or area. This makes it easier for plumbers and maintenance personnel to locate and identify specific sections of the plumbing system.

Pipe sizing identification: PPR pipes of different colors can also indicate different pipe sizes. For example, manufacturers may use specific colors for pipes of different diameters (e.g., yellow for 20mm pipes, green for 25mm pipes, etc.). This helps in quickly identifying the required pipe size during installation or maintenance.

Plumbing code compliance: In some regions, plumbing codes or standards may specify the use of specific colors for certain types of pipes. This ensures uniformity and compliance with regulations, making it easier for inspectors and plumbers to verify the correct installation and usage of pipes.

It's important to note that the specific color coding conventions for PPR pipes can vary between different countries, regions, or even local plumbing practices. Therefore, it is advisable to consult local plumbing codes or standards to understand the specific color coding guidelines applicable in your area.
