What Type of Pipe Is Used for Gas Lines


What Type of Pipe Is Used for Gas Lines?

When it comes to installing gas lines, it is crucial to select the right type of pipe to ensure safety and efficiency. Gas lines are used to transport natural gas or propane from the main supply to residential or commercial buildings. Here are some commonly used types of pipes for gas lines:

1. Steel pipes: Steel pipes are the most common choice for gas lines due to their durability and strength. They can withstand high pressure and extreme weather conditions. However, steel pipes are prone to corrosion over time, so they require regular maintenance and coating.

2. Copper pipes: Copper pipes are another option for gas lines. They are corrosion-resistant, making them a reliable choice. However, copper pipes can be more expensive than steel pipes and may require special connectors for gas applications.

3. Polyethylene (PE) pipes: PE pipes are lightweight, flexible, and resistant to corrosion and chemicals. They are often used for underground gas lines due to their durability and ease of installation. However, special fittings are required to connect PE pipes.

4. Corrugated stainless steel tubing (CSST): CSST is a flexible pipe that is easy to install and requires fewer fittings. It is made of stainless steel and coated with a protective jacket. CSST is commonly used for residential gas lines due to its flexibility and resistance to corrosion.

5. PVC pipes: PVC pipes are not recommended for gas lines as they are not suitable for conveying natural gas or propane. PVC pipes can crack or break under pressure, leading to hazardous leaks.
