Pipeline Labeling

Pipelines are used to transport a wide range of different things throughout facilities every day. They are widely seen as the safest and most efficient way to move liquids and gasses from place to place as they are needed. When using pipelines in a facility, it is necessary to ensure that the pipes that are used are properly labeled.

If a pipe is not labeled, people working on the piping may not know what is in the pipe, and therefore not take the necessary precautions. This is especially important since pipes carry such a wide range of different solutions, making it impossible to predict what is inside without tracing the pipe back, which would be inefficient.

If an employee opens up a pipe that he expects to be water, but it is actually some type of toxic gas or fluid, it is easy to see how this could cause a very serious problem. Fortunately, pipeline labeling is a fairly easy process, and can virtually eliminate the risk of someone working with a pipe without knowing what is flowing inside.

When learning about the best ways to label piping in a facility, it is a good idea to follow the free pipe-marking guide offered by Creative Safety Supply.

How to Label Pipelines

Labeling pipes can be an easy process, as long as the person or team doing the labeling has the right equipment, and is following all the rules and regulations governing this process.  Investing in getting everything that is needed is well worth the effort for any company that has piping that needs to be labeled.

Pipe Marking Tape

Pipe marking tape is commonly used to help the pipes stand out, and convey information about what is being transported inside the pipe. This can be general colored tape that is made for pipes, or companies can use pipe marking labels. Labels are necessary whenever information has to be passed along.

Using this type of tape it is easy to apply the labels to any type of pipe that is in use. Labels can be made to the exact size that is needed based on the diameter of the pipe that needs to be marked. This can only be done if the right equipment is available, or if the facility orders custom made pipe marking tape to be used in that facility.

Pipe Marking Equipment

Most facilities that do their own pipeline markings will want to have an industrial label printer to create and print off the labels that are needed. These printers come with software that can be used to design the exact type of label that is needed so that it complies with ANSI and other requirements. One of the best things about having a label printer like this on site is that the labels can be customized as needed, and they can be printed off whenever a new one is required.

Pipe markings are often quite different from other types of labels, so it is important to plan everything out and get it right. These markings should include an arrow to indicate which direction the pipe is flowing, and additional information about what is in the pipe. Reviewing the requirements for pipeline markings is going to be essential for safety and compliance. These requirements are discussed later in this article.

Pipe Markers

There are a variety of different designs of labels that can be used. The specific one that is right for a given situation will depend on things like how much information needs to be conveyed, what is in the pipes, the environment that the pipe is in, and much more. The following are some common types of pipe markers that facility owners or safety managers should be aware of so they can use them if appropriate:

  • Arrow Tape - Arrow tape is simply a strong tape that has arrows on it. When installed, it will clearly show which direction the pipe flows. This is often used along with pipe marking labels or signs.
  • Shrink Wrap Labels - Wrapping a pipe with a label and then having it shrunk down to tightly fit over the pipe is an effective option. This is typically done with a heat gun, and will allow information to be shown on all sides of the pipe itself.
  • Pipe Markings - Pipe markings, which are the standard pipe labels that contain information about what is in the pipe, among other things, are likely the most common way that a pipe is labeled today. They offer important information both for those working with the pipes, and emergency workers who need to be aware of what is in them.
  • Patterned Tape - Patterned tape can draw additional attention to a pipe when necessary. This could be a black and yellow stripe that is meant to remind people to take caution when working on the piping. Like the arrow tape, this option is typically going to be used along with standard pipe marking labels.

Pipeline Labeling Standards

There are many pipeline labeling standards that need to be followed. Some of these standards are put in place by regulatory agencies like OSHA, and others are recommended by ANSI and other institutions. Still others will simply be policies put in place by a given company. There are many standards regarding what the labels must say, as well as where they must be placed.

ANSI Pipe Labeling

The ANSI A13.1 standard is the most commonly followed standard for marking pipes today. It is often referred to as ANSI/ASME A13.1, but whatever it is called, it should be known by all facilities. It received a major update in 2007, and then was again reaffirmed in 2013.

While ANSI is not a governmental agency, and has no legal power to force any company to follow their standards, almost all companies do try to comply with them. In addition, when OSHA and other governmental agencies choose to make requirements regarding pipe markings, they will almost always turn to ANSI standards as the bases of the law.

ANSI is a very respected institution throughout virtually every industry, which is why businesses tend to listen to their recommendations. Their standards are made in such a way as to help improve safety, without putting any type of undue burden on the businesses or the employees. This is an excellent balance that has helped to drive improved pipe safety for years.

Pipe Color Code

Labels used on pipes will typically need to follow the color codes established by ASME in their A13.1 standards, which were most recently updated and affirmed in 2013. The following are the most common pipe color code standards that will be used in most facilities:

  • White Text on Red Background - This is to be used for fire-quenching fluids.
  • Black Text on Orange Background - This is to be used for fluids that are toxic and corrosive.
  • Black Text on a Yellow Background - This is for flammable fluids.
  • White Text on Brown Backgrounds - This is for combustible fluids.
  • White Text on Green Background - This is for water that is for cooling, boiler feeds, and other needs.
  • White Text on Blue Background - This is for pipes containing compressed air.

There are also a variety of different color combinations that are reserved for 'user-defined' things. This is important since it will allow facilities to use pipe markings with colors that they can be confident won't mean something else in the coming years.

The current user-defined colors for pipe markings are white text on purple background, white text on grey background, white text on black background, and black text on white background. It can be helpful to carry a quick pocket guide to identify what each of the colors mean. Many facilities will also put up larger signs that contain the color meanings, which would look something like this:

Keeping Pipe Markings Visible

Once pipe markings are applied to the pipes, it is important to ensure they remain visible to everyone who may be in the area. This would include people who are working directly on the pipes, and those who may be working around them at any time.

To ensure a pipe remains visible, it is necessary to ensure there is lighting available to show the markings. It is also important to keep the labels clean. Pipe markings are made with a high quality materials so that they can be cleaned using just about any normal cleaning solutions. Maintenance teams can wipe them down if they become dirty with dust or grease.

Should a label become damaged, it needs to be replaced right away to ensure the information displayed on the label is always easy to see. Even if most people working in the area have become familiar with what is on the labeling, emergency responders would not know, which is why it is so critical to ensure that pipeline markings are easily visible and readable at all times.
