Importance of Pipe Labels

In industrial or plant settings, effective pipe labelling is a crucial factor in enabling the rapid identification of pipe contents and comprehending valve functions. This is accomplished by strategically employing appropriate colour codes and informative legends.

Labels must be positioned in a way that ensures easy visibility to plant personnel as they approach. They should provide immediate and comprehensive information about pipe contents, flow direction, and the safety status of the contents, whether they pose a hazard or are safe to handle.

When defined and installed correctly, pipe labels offer several benefits:

Enhanced Safety: Improves safety by clearly identifying pipes and their potential hazards.

Facilitates Maintenance and Reduces Downtime: Simplifies maintenance procedures, reducing downtime and aiding quick troubleshooting.

Streamlines Commissioning: Simplifies the commissioning process by facilitating a logical and organised workflow, leading to enhanced efficiency and reduced completion time.

Ensuring adherence to regulations: Promoting a secure and compliant industrial workspace.

Key Considerations when Choosing a Pipe Label

When it comes to choosing the right pipe labels, it’s vital to focus on these critical areas:

Standard Format: Adhere to the appropriate standard format, ensuring that your labels follow ANSI-ASME standard A13.1-2020 standards. Additionally, make sure that the texts on the labels are clear and well-structured, effectively communicating information about pipe contents and potential hazards.

Colour Schemes: Select colours based on the specific application of the pipes. Using the right colours can help convey important information about the pipes’ contents.

Text Height: Determine the appropriate text height based on the size of the pipe. This ensures that labels remain legible and informative.

Visibility: Ensure that your labels are highly visible within the infrastructure. This is crucial for quick and easy identification, enhancing overall safety.

Durability of Labels: Opt for labels that possess the durability required to withstand the harsh conditions often encountered in industrial environments.

At Million.com.sg, we seamlessly incorporate these vital considerations into our label customisation services. This guarantees that your labelling needs not only meet but exceed industry best practices, ensuring a safe and compliant working environment.

How to Stick the Pipe Label Properly

Pipe labels should be positioned for easy visibility from the standard angle of approach. For instance, if the pipe is overhead, the label should be located below the pipe’s centreline, and if the pipe is at or below eye level, the label should be above the centreline.

For optimal visibility, adhere to the ANSI-ASME standard A13.1-2020 standards for pipe identification, which recommends the following:

  • Use arrows on labels to indicate the flow direction.
  • Label pipes adjacent to valves and flanges.
  • Place labels at points where the pipe’s direction changes.
  • Label pipes every 25 to 50 feet on straight sections.
  • Mark pipes on both sides of floor or wall penetrations.

If necessary, consult a workplace safety consultant to ensure compliance with the correct standards.
