Do You Know The Identification Lines on PE Pipes?

Do you know the identification lines on PE pipes?

In construction, municipal, industrial and other fields, PE pipes are widely used for their excellent performance. The identification lines on PE pipes are not only for decoration, but also key to distinguishing their uses and properties. Let's explore the information conveyed by these identification lines and knowledge about PE flame-retardant pipes.

I. Identification lines on PE pipes

• Red identification line: PE mine pipe

PE mine pipes are specially designed for mining environments like coal mines. They have excellent flame-retardant and anti-static properties, ensuring safety in flammable and explosive mine environments. PE mine pipes can be divided into five types: mine water supply/drainage pipes (KS), mine shotcrete pipes (KJ), mine positive pressure air pipes (KFZ), mine negative pressure air pipes (KFF), and mine gas drainage pipes (KW). These pipes play important roles in water supply, drainage, air supply, shotcrete and gas drainage in mines, ensuring safe and efficient mining production.

• Blue identification line: PE water supply and drainage pipes

PE pipes with blue identification lines are mainly used in water supply and drainage systems. PE water supply pipes, as upgraded products of traditional steel and PVC drinking water pipes, can withstand certain pressure and are often used in urban water supply networks to provide safe drinking water transmission for residents and industries. PE drainage pipes, with advantages like wear resistance, acid and alkali resistance, high temperature and high pressure resistance, are increasingly replacing traditional steel and cement pipes in sewage treatment and municipal engineering, becoming the preferred material and effectively solving urban drainage problems while enhancing the efficiency and lifespan of drainage systems.

• Yellow identification line: PE gas pipe

PE gas pipes, used for natural gas and liquefied petroleum gas (LPG) transmission, replace traditional steel and PVC gas pipes. PE gas pipes have orange and yellow identification lines. Orange lines indicate PE100 material grade, while yellow lines indicate PE80. These pipes ensure safe and stable gas supply for urban and industrial use.

• No color line: HDPE siphon drainage pipe

Besides colored PE pipes, HDPE siphon drainage pipes have no color lines. They use siphon force to create negative pressure, moving rainwater or sewage from high to low areas. These pipes are used in high-rise buildings and commercial complexes, improving drainage efficiency and reducing waterlogging.

II. Introduction to PE Flame-retardant Pipes

Definition and Characteristics PE flame-retardant pipes are polyethylene pipes with excellent flame-retardant properties, made through special processes. They're created by adding flame retardants or other modifiers to regular PE pipes. This allows them to inhibit combustion and slow fire spread when exposed to flames, enhancing the safety and reliability of pipe systems. PE flame-retardant pipes not only have good flame-retardant properties but also retain the original advantages of PE pipes, such as corrosion resistance, wear resistance, and impact resistance, ensuring stable performance in various complex environments.

III. Application Fields

PE flame-retardant pipes are widely used, particularly in places with high fire safety requirements. In power projects, they can be used as cable protection pipes, preventing fires caused by cable overheating or external flames, and ensuring safe power transmission. In industrial buildings like chemical plants and pharmaceutical workshops, where flammable and explosive gases or dust may occur, they can be utilized in ventilation systems and material conveyance pipes, reducing fire and explosion risks, and ensuring safe production. Additionally, PE flame-retardant pipes are applied in communication projects, petrochemical industry, fire fighting systems, and more, offering crucial support for the safe development of various industries.

IV. Performance Advantages

Outstanding flame retardancy: When PE flame-retardant pipes encounter flames, they can quickly form a heat-insulating protective layer to prevent further flame spread. Their flame-retardant effect complies with relevant national standards and industry regulations, effectively reducing the probability and harm of fires.

Good high-temperature resistance: In high-temperature environments, PE flame-retardant pipes can maintain good physical and chemical properties. They won't soften, deform, or decompose due to rising temperatures, ensuring the normal operation of pipe systems.

Low smoke and halogen-free characteristics: When PE flame-retardant pipes burn, they produce less smoke and no halogen components, preventing the generation of toxic and harmful gases. This helps ensure the safe evacuation of people during fires and the smooth conduct of firefighting operations.

V. Conclusion

The identification lines on PE pipes are crucial for distinguishing their uses and properties, with different colors representing applications in various fields. As a special type of pipe, PE flame-retardant pipes play an important role in places with high fire safety requirements. Understanding the meaning of PE pipe identification lines and the relevant knowledge about PE flame-retardant pipes helps us correctly select and use pipes in practical applications, ensuring project safety and quality.
