Is PEX Pipe the Ultimate Solution for Airline Air Lines? Discover the Revolutionary Truth!

PEX (cross-linked polyethylene) pipe has gained popularity in recent years as a versatile and durable option for plumbing systems. Its flexibility, corrosion resistance, and ease of installation make it a compelling choice for a wide range of applications. However, one question that often arises is whether PEX pipe is suitable for use in air lines. This blog post will delve into the pros and cons of using PEX pipe for air lines, examining its performance, safety, and compatibility.

Understanding PEX Pipe

PEX pipe is a type of plastic tubing that is manufactured from cross-linked polyethylene. This process creates a strong and flexible polymer network that provides PEX pipe with several advantages, including:

• Flexibility: PEX pipe is highly flexible, making it easy to bend and maneuver around obstacles during installation.
• Corrosion Resistance: PEX pipe is resistant to corrosion from chemicals, minerals, and oxygen, which makes it a long-lasting option for plumbing systems.
• Ease of Installation: PEX pipe can be easily cut and connected using specialized tools, reducing installation time and labor costs.

Pros of Using PEX Pipe for Air Lines

• Flexibility: The flexibility of PEX pipe makes it ideal for routing air lines through tight spaces or around obstacles, eliminating the need for elbows or fittings.
• Corrosion Resistance: PEX pipe’s resistance to corrosion ensures that it will not corrode over time, reducing the risk of leaks and maintaining air quality.
• Durability: PEX pipe has a long lifespan and can withstand high pressures, making it a reliable choice for air lines.
• Cost-Effective: PEX pipe is relatively inexpensive compared to other piping materials, making it a cost-effective option for air line installations.

Cons of Using PEX Pipe for Air Lines

• Temperature Sensitivity: PEX pipe can become brittle when exposed to high temperatures, which makes it unsuitable for use in air lines that carry hot air.
• Permeability: PEX pipe is slightly permeable to oxygen, which can lead to oxidation of metal components in the air line over time.
• UV Susceptibility: PEX pipe is susceptible to degradation when exposed to ultraviolet radiation, which requires it to be protected from sunlight in outdoor applications.

Considerations for Using PEX Pipe for Air Lines

• Temperature: PEX pipe should only be used in air lines that carry air at temperatures below 180°F (82°C).
• Oxygen Permeability: The permeability of PEX pipe to oxygen should be considered when using it in air lines that are sensitive to oxidation.
• UV Exposure: PEX pipe should be protected from UV radiation in outdoor applications by using UV-resistant coatings or by installing it in shaded areas.
• Installation: PEX pipe should be installed according to manufacturer’s recommendations and using proper fittings and tools to ensure a secure and leak-free connection.

Compatibility of PEX Pipe with Air Line Components

PEX pipe is generally compatible with most air line components, including:

• Air compressors
• Air filters
• Air dryers
• Air tools
• Air distribution systems

However, it is important to consult with the manufacturer of the air line components to ensure compatibility and avoid any potential issues.

Wrap-Up: Making an Informed Decision

Whether PEX pipe is good for air lines depends on the specific application and the considerations discussed above. For air lines that carry air at temperatures below 180°F, are not sensitive to oxidation, and are protected from UV exposure, PEX pipe can be a suitable and cost-effective option. However, for applications that involve high temperatures, oxygen sensitivity, or UV exposure, alternative piping materials may be more appropriate.

FAQ

1. Can PEX pipe be used for compressed air lines?
Yes, PEX pipe can be used for compressed air lines as long as the air temperature remains below 180°F.

2. Is PEX pipe safe for use in air lines that supply breathing air?
PEX pipe is not recommended for use in air lines that supply breathing air, as it may release trace amounts of chemicals that could be harmful to inhale.

3. How do I connect PEX pipe to air line components?
PEX pipe can be connected to air line components using specialized fittings and tools. It is important to follow the manufacturer’s instructions for proper installation.

4. What is the maximum pressure rating for PEX pipe in air lines?
The maximum pressure rating for PEX pipe in air lines varies depending on the specific type and size of pipe used. Consult with the manufacturer for specific pressure ratings.

5. How long does PEX pipe last in air lines?
PEX pipe has a long lifespan and can last for decades in air lines, provided it is properly installed and maintained.
