Pipe Markers

I.ANSI/ASME A13.1 Pipe Labeling Standards

The ANSI/ASME A13.1 standard provides clear guidelines for pipe marking, ensuring that the contents of pipe systems can be quickly and accurately identified. Key points of this standard include:

• Size Requirements：The size of pipe markers must be determined based on the pipe diameter to ensure visual clarity.

• Color Specifications：Colors are used as an auxiliary means to identify the type of hazard posed by the medium inside the pipes. For example, black background with orange text is used for flammable fluids, while black background with yellow text is used for combustible fluids.

• Visibility and Readability：Pipe markers must have high visibility and readability, providing immediate information to staff during both routine operations and emergencies.



• Font size and label length

II. Ammonia Pipe Marking Standards

For ammonia pipelines, we provide a series of markings that comply with industry standards, emphasizing the hazardous characteristics of ammonia.

• Special Colors and Symbols：Ammonia pipelines typically use striking colors (such as yellow or orange) and specific chemical symbols for identification.

• Clear instructional information：The label should include the words "ammonia" or "Ammonia", as well as possible hazard warnings and preventive measures.

• Weather resistance and durability：Considering that ammonia pipelines are usually located in industrial environments, our markings are made of highly durable materials and can withstand the erosion of harsh conditions.

III. NFPA 99/CGA C-9 Pipe Marking

NFPA 99 and CGA C-9 standards specify the labeling requirements for gas pipeline systems in medical facilities, ensuring the safe delivery and use of medical gases.

• Color Coding：Specific color codes are used to distinguish different pipeline systems based on the type and purpose of the gas.

• Clear Identification：Markings should include the name of the gas, its purity, and any relevant safety information.

• Compliance：Our pipe markings fully comply with the latest NFPA 99 and CGA C-9 regulations, ensuring the safe operation of medical facilities.

IV. ISO/DIS 14726 Marine Vessel Pipe Marking

ISO/DIS 14726 provides standardized labeling norms for pipe systems on marine vessels, aiding crew members in quickly identifying pipe contents in complex and dynamic ship environments.

• International Standards：Universal colors, symbols, and text are used to describe pipe contents and their properties.

• Durability and Water Resistance：Given the unique marine environment, our pipe markings are made from waterproof and salt-fog resistant materials.

• Easy to identify：The mark design is simple and clear, allowing for quick recognition even in low light or restricted visibility conditions.

V. Water treatment pipeline identification

Pipe markings in the water treatment system are of crucial importance. They ensure the proper management and safe use of water resources.

• Color distinction：Use colors to distinguish different types of water treatment pipelines, such as clear water, wastewater, reclaimed water, etc.

• Clearly identify the content：The label shall include the purpose of the pipeline, the flow direction, and any relevant water quality information.

• Weather resistance and environmental friendliness：Made of environmentally friendly and highly weather-resistant materials to ensure that the markings remain clearly visible during long-term use.
