Color Coding of Pipeline and Piping Identification
Oil and Gas Industries, Process industries are complex installations. 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.

Identifying the material pipeline transporting without a proper pipe color code is extremely difficult. Systematic color coding of pipelines and piping systems is essential to reduce the safety hazard and the possibility of mistakes in identification and accidents associated with the wrong identification of pipelines during an emergency situation. Uniformity of color marking promotes greater safety, lessens the chances of error, and reduces hazards in handling material inside the pipelines.

National and international standards provide the guidelines for uniform color coding in industries that are used to color code of pipes to identify.

ASME A13.1 - Scheme for the Identification of Piping Systems
BS 1710 - Specification for Identification of Pipelines and Services
IS 2379 - Pipelines Identification Colour Code
These standard uses different color code methodology to identify the pipe material. They use a base color, band color, letters, and direction arrow to identify fluid inside the pipeline.
ANSI/ASME A13.1 - Scheme for the Identification of Piping Systems
The purpose of the ASME/ANSI A13.1 Standard is to establish a common system that assists in the identification of hazardous materials conveyed in piping systems and their hazards when released into the environment.

ASME A13.1 - 2015 edition has six fixed colors, and four users define colors that can be used to identify hazardous material. In this standard, the following categories are used;

Flammable - Fluids or vapor or produce vapors that can be ignited and continue to burn in air.
Combustible - Fluids that can burn, but are not flammable.
Oxidizing - Oxidizing fluid is any gas or liquid that may, generally by providing oxygen, cause or contribute to the combustion of other material more than air does.
Toxic and Corrosive - Fluids that are corrosive or toxic, or will produce corrosive or toxic substances when released.
Fire Quenching - Fluid Such as water, foam, and CO2 used in sprinkler systems and firefighting piping systems.

Packaging & Shipping

1. All of our stainless steel seamless pipe & tubes are packaged as per international standard to prevent any possible damage or loss. By default, we will use thick woven plastic bag to bundle the finished pipes together in batches.
2. For some special pipes & tubes that are vulnerable to dirt, scratches, stress or rough handling, we will suggest wooden case for protection. Kindly note, wooden case can incur extra cost, not only its own cost, but also the increased freight cost, which is especially true for air transportation.
3. For enhanced customer experience, we also provide dedicated package as per your special requirements.
