Color Coding

Color coding of pipelines and piping materials are standard industry practices.  Color marking will make identification easier for raw material and fluid that being transport by the pipe. There are various national and international Pipe Color Code Standards are available.

Color Coding of Piping Material – PFI ES-22

Why the color coding of piping material required ?

During construction and fabrication, various grades of carbon steel, alloy steel, and stainless steel are used. To avoid mixing of this material and easy storing and retrieving in the warehouse, piping components such as pipe, fittings, flanges, and valves are color coded.

All most all company has their own color-coding system. Pipe Fabrication Institute (PFI) Standard ES-22 provides Piping Materials color coding requirements for most used piping material grades. It also provides guidance on marking location on piping components.

Color Coding of Pipeline and Piping Identification

Oil and Gas Industries, Process industries are complex installation. Piping systems are used in these plants to transport various fluids. These pipelines transport various industrial materials such as gases such as Air, Nitrogen, Oxygen, Hydrogen, etc., liquids such as water, acids, hydrocarbon, toxic materials, etc.

Without proper pipe color code, it is extremely difficult to identify the material pipeline transporting. To reduces the safety hazard, reduce the possibility of mistakes in identification and accidents associated with the wrong identification of pipelines during the emergency, systematic color coding of pipelines and piping systems is essential. Uniformity of color marking promotes greater safety, lessens the chances of error, and reduces hazards involved in the handling of material inside the pipelines.
