Pipeline Color Code Standard and Labels Charts -A Complete Guide


Pipeline Color Code Standard and Piping Color
Codes Chart Welcome to the hardhatengineer.com. In this video, you will learn about color
coding of pipe material and pipeline using American, British and Indian standard. You will learn about which color to use; the
size of the color label and the location of the color coding. So please watch full video. Please subscribe to my channel because it

are standard industry practices. Color marking will make identification easier
for the raw material and fluid that is transported by pipeline. There are various national and international
Pipeline Color Code Standard available. Such as
1. ASME A13.1 – Scheme for the Identification
of Piping Systems 2. BS 1710 – Specification for Identification
of Pipelines and Services 3. IS 2379 – Pipelines Identification Color
Code 4. PFI ES-22 – Recommended Practice for Color
Coding of Piping Materials Let’s start with
Color Coding of Piping Components As per PFI ES-22
Why color coding of piping components? 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 own color coding
system. Pipe Fabrication Institute (PFI) Standard
ES-22 provides Piping Materials color coding requirements for most commonly used piping
material grades. It also provides guidance on marking location
on piping components. Here in the images, you can see the solid
green strip on the elbow, tee, and reducer. This is killed carbon steel. If there is a white strip with any other color,
it indicates it is a welded product. See this reducer. Here you can see the example of stainless
steel 304L reducer with two black strips and welded ss317L pipe. This RTJ flange is of alloy steel grade A335
Gr P12. Here are the examples of color coding on the
valve. This is full chart of the color code; you
can check that by visiting my website hardhatengineer.com. The second point of this video is color coding
of the pipeline. Before I explain you further, please like

Oil and Gas and Process industries are complex installations. Piping systems are used in these plants to
transport various fluids. These pipelines transport various industrial
materials gases such as Air, Nitrogen, Oxygen, Hydrogen, etc., liquids such as water, acids,
hydrocarbon, toxic materials and so on. Without proper color coding, it is extremely
difficult to identify the fluid being transported by pipeline. To reduces the safety hazard and the possibility
of mistakes in the identification and also the accidents associated with wrong identification
of pipeline during an emergency situation, systematic color coding of pipeline and piping
system is essential. Uniformity of color marking promotes greater
safety, reduces the chances of error and hazards involved in the handling of material inside
the pipelines. There are national and international standard
that provides the guidelines for uniform color coding in industries. As said earlier, these standards are ASME
A13.1, BS 1710 and IS 2379. The purpose of 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. These standard uses different methodology
to identify the material. They use a base color, band color, letters
labeling and direction arrow to identify fluid inside the pipeline. Let’s check the requirements of the three
standards. ASME A13.1 – Scheme for the Identification
of Piping Systems ASME A13.1 which was earlier ANSI A13.1. ASME A13.1 – 2015 edition has six fixed
colors, and four users define colors that can be used to identify the hazardous material. In this standard, fluids are categorized as
a Flammable, Combustible, Toxic, Corrosive and Fire Quenching. You can see these colors in the table. Size of Label and Letters are also specified
in the standard. Here you can see the example of the labeling. Now all these dimension tables are available
on my website hardhatengineer.com so you can easily access them at your convenience. The second standard is
BS 1710 – Specification for Identification of Pipelines and Services BS 1710 uses two types of color coding to
identify the content of pipe and hazard. 1. Base color that used to indicate the content
of the pipe. And
2. Safety colors that used as a band color which
applied in conjunction with the base color to create various service identifier. Here in this table you can see the basic and
safety colors. BS 1710 -2014 has two types of labeling, 1st
when only basic identification color is used. As shown here. You can also see the requirement of the minimum
width of the band. 2nd way is basic identification color with
safety color. As shown here. You can also see the requirement of the minimum
width of the band. The third strandard is
IS 2379 – Pipelines Identification Color Code
IS 2379 is Indian Standard for the color coding requirements. It is quite comprehensive and little complex
as compared to BS and ASME standard. IS 2379 is more in line with BS 1710. It used the ground color, 1st band color,
second band color and letter labeling to identify fluid content and associated hazards. Refer table for the ground color that used
in pipeline marking. Here in this table, I have shown the color
coding of some of the most commonly used fluid in the refinery. Here you can see the Size of Label and Letters
as per IS 2379 2006 edition. Location and the position of the color coding
labels. Coloring and identification labels on the
pipe should apply in such a way that it is clearly visible from the all the approach
especially when pipes are overhead. ASME B13.1 and IS 2379 provides guidance on
the positions of the labeling. As per the general guideline provided in the
standards label shall applied At close to valves or flanges. At intersection points, adjacent to changes
in direction and at branches. where pipes pass through walls, floors, and
culvert. at start and end points, at regular interval on straight pipe and at battery limits. You can check all the color coding tables
and label dimension by visiting my website hardhatengineer.com. The link is given in the description. This is all about color coding. Don’t forget to subscribe to my channel. Please like and share my video with your friends. If you want to request a video, write in the
