How to Install Pipe Markers
How to properly install pipe markers
Pipe labeling is crucial to the safety of any facility that contains a pipe system. Labels and markers for pipes are required in many cases and keeping abreast of guidelines is ethical and responsible. A properly set up labeling system is also more convenient. While labeling a pipe system takes initial planning, it’s entirely manageable with the right knowledge and preparations. Use the following guide to install pipe markers in the most efficient, accurate way for your specific system.
How to label pipes: A step-by-step guide
There are many types of labels that you can choose from and customize to the type of piping being installed or updated. The size, color, pipe material and condition, diagrams to include, adhesive, and snaps should all be considered when deciding which pipe labels to use. Follow these steps to ensure you’re choosing the right labels for the job.
Step 1: Know your piping system
First and foremost, you should take stock of the piping system you are preparing to label. Become familiar with the system by reviewing diagrams and examining existing pipes and their associated markers. You should also keep in mind that your existing system may not have followed pipe marking guidelines.
Assessing the pipe system is crucial for ensuring safety, efficiency, and compliance. Before marking pipes with their associated markers and labels, a thorough evaluation should be conducted to understand the system's characteristics and requirements. Here are some key piping layout considerations:
- Project requirements: Including building codes, budget, licensing, and guidelines from the client and owner of the building regarding layout, design, and operations;
- Spatial arrangements: Such as how pipes are laid out, including any potential bottlenecks or site-specific constraints that need to be addressed when labeling;
- Pipe contents: Including the fluid or gas type within the pipes, pipe materials, sizing, pressure ratings, and temperature limits.
These elements are crucial in the ultimate piping design and how each pipe should be properly labeled. Also, remember to thoroughly inspect previous piping, regardless of labeling.
Step 2: Choose the right types of pipe markers
Your analysis of your piping system or your knowledge of the project requirements for new construction and installation will guide you in choosing the right pipe markers for the job.
When dealing with potentially hazardous substances, it’s of utmost importance to label the new piping correctly. Anyone who comes into contact with these pipes, including contractors, employees, first responders, maintenance staff, or the public, should be able to quickly and accurately identify the purpose of each pipe and make judgment calls on how to interact with them safely.
The main types of pipe markers include:
-
Self-adhesive: Self-adhesive pipe markers and labels are adaptable, sticky-backed labels suitable for indoor and outdoor pipes of all shapes and sizes, including small and curvy pipes. Just make sure that you are applying to a clean, dry surface for optimal adhesion. There are special opti-code self-adhesive pipe markers that follow the ANSI / ASME A13.1 standard when used in conjunction with flow arrows.
-
Snap-around: Snap-around pipe markers utilize snaps instead of adhesives, making them suitable for any pipe. This is best when working with rough, dirty, greasy, or oily surfaces or harsh indoor or weather conditions. The wrap-around design can also accommodate larger pipes using nylon ties for extension.
-
High-performance: High-performance pipe markers are specifically designed to withstand harsh conditions, including extreme weather. They typically come in self-adhesive and wrap-around and can be applied to any size or shape pipe. These durable pipe labels are made of resistant materials.
Once you have determined which types of pipe markers are most suitable for your specific labeling project, you can make a purchase list to order from.
Step 3: Design and create the labels
When ordering your markers, you have several options. Most likely, you will need to customize at least some of the necessary labels. Custom pipe markers can be printed in-house if you have the proper equipment, but it’s much easier and cost-effective upfront to order from a custom label company. They will likely have many of the pre-made certified labels that include common wording and symbols. Custom options are also available if you need different words or phrases than those in the traditional pipe coding legend.
Step 4: Install pipe markers
Applying labels to your pipes can be intimidating with all of the rules to doing so correctly. Luckily, there are resources available to help you along the way. Pipe markers and valve tags should be affixed visibly, especially when indicating the presence of hazardous materials.
You must also include arrows that indicate flow direction. As mentioned above, you should assess the type and size of the pipe, as well as the ability to clean the surface and how much it is exposed to weather and tear. To ensure the most seamless application, you can even use a handy pipe marker applicator to assist with tricky spots and speed up the process.
Understanding pipe labeling standards
An intricacy of pipe labeling is deciding which set of standards to use. There are various guidelines but, in some cases, one set of standards may not apply to every system. Instead, you will have to learn the different types of guidelines and use your best judgment to apply them to your specific facility and piping infrastructure.
OSHA and ASME / ANSI standards
The two governing bodies that set pipe labeling standards are OSHA and ASME / ANSI. OSHA doesn’t require specific labeling but instead outlines guidelines of what you should and shouldn’t do. They aim to protect employees from hazardous materials in the workplace, and piping labels are an important part of identifying those hazards. They offer color-coding standards and recognize the ASME / ANSI standard, A13.1, as the ideal blueprint for pipe identification. Here’s a brief overview of what’s included in the guidelines:
- OSHA color codes
- A legend of symbols
- The size of the label
- Placement in key areas with high visibility
- Durability to hold up to the conditions of the pipe environment
- Identification of abandoned piping
ASME / ANSI A13.1 is the most recognized pipe-labeling identification standard in the United States. It’s a valuable resource that should be referred to often and monitored for any updates.
Specialized standards
There are often industry- and system-specific standards in place in addition to those set forth by OSHA and ASME / ANSI. These are tailored to convey essential information related to the unique requirements of a given industry or piping system. For instance, in the context of ammonia refrigeration systems, adherence to specialized labeling standards is imperative due to the hazardous nature of ammonia and the need for precise identification.
Jobsites like petrochemical plants, water treatment facilities, or pharmaceutical manufacturing, may have distinct substances and processes. These industries have specific standards for pipe labeling to enhance operational safety and streamline facility management. It’s crucial to determine these safety standards when pipe labeling in any circumstance.
Common mistakes in pipe marker application and how to avoid them
Issues with pipe labeling can make for an unsafe environment. Some of the most typical mistakes include:
- Dirt that covers labels: Proper maintenance and inspections can reduce the risk of unclear labeling due to excess dirt and debris.
- Torn, peeling, or faded labels: Improper maintenance or fragile labels can lead to rips, tears, and faded lettering. Investing in high-quality pipe labels that are designed for specific surfaces, and performing regular inspections and updates can avoid this issue.
- Poor visibility: Follow OSHA and ASME / ANSI guidelines and use your best judgment when placing labels. They should be placed in high-visibility areas where it is easiest to spot them.
- Unclear wording or symbols: Again, following the guidelines will ensure you are clearly marking the piping system. Word and symbol sizes should be commensurate with the size of the pipe. You can also work with the building manager or other external help to ensure readability and clarity.
Proper planning and dedicated efforts are the key to ensuring compliant, high-quality, and durable pipe markings. Adhering to industry-specific and system-specific standards, conducting regular maintenance, considering optimal label placement, and prioritizing visibility and clarity are essential steps. By investing the necessary time and resources, you can create a safer environment, minimize the risk of errors, and enhance overall operational efficiency through pipe labeling.
