What Type of Gas Line Do I Need?
April 15, 2022
Whether you’re building a new home, renovating your existing house, or upgrading to gas appliances, you may need a new gas line installation or gas line repair to get the project done. But how do you know what type of gas line you need? The simple answer is: It depends.
Hiring a trained and certified plumbing contractor is always the safest option when installing or repairing your gas piping. They can help you determine which type of gas line is best for your project based on the following factors:
- Durability and flexibility
- Geographic location
- Interior or exterior applications
A contractor may recommend a certain type of gas line for you, or you may be able to request one. Either way, considering the above factors can help you make an informed decision that aligns with your project needs and budget.

Different types of pipes for gas lines have varying prices. So if you’re on a tight budget for your project, you may be able to choose a less expensive option that still meets all your other project needs. Below, we’ve listed the most commonly used pipe material for gas lines, along with their average cost (labor not included).
- Black Iron: $20 to 25 per linear foot
- Flexible corrugated stainless (CSST): $8 TO $10 per linear foot
- Galvanized steel: $5 to $12 per linear foot
- High-density polyethylene piping (HDPE): $2 to $5 per linear foot
Of course, other factors will also affect the overall price tag of your project, including:
- Labor cost: More qualified contractors are typically more expensive. However, this also means you likely won’t have to pay for repeat work or repairs and replacements down the line.
- Line length: The longer the gas line, the more materials, time, and labor are required to complete the job.
- Line location and complexity: It can be difficult for a contractor to access a gas line, depending on its location. More inaccessible gas lines will require more labor and time. Afterward, you may need to pay for additional cosmetic work, such as landscaping or drywall repairs.
On average, the cost to run a gas line (including materials, labor, and permits) is about $550, with typical prices ranging from $265 to $850 or about $20 per linear foot. An experienced contractor can help you narrow down your options to the types of gas lines that best meet your budget while also considering other factors.
Durability and Flexibility
Not all gas pipe materials are created equal, and some are more durable than others.
Again, let’s take a look at the four most commonly used pipe materials for gas lines to help you determine which might be best for your project based on durability and flexibility.
Black iron is the most common material used to make gas pipes. Contractors often prefer it over other types of materials due to its strength, heat resistance, and because it fits snugly together with a compound that ensures an airtight seal. However, that seal can deteriorate with time, and the piping can corrode. Without routine maintenance, that could become a costly problem. Since it’s also not as flexible as other options, it requires more joints, which increases the risk of leaks.
Flexible Corrugated Stainless Steel Tubing (CSST):
CSST is another popular gas piping option and can be used in tighter spaces because it’s more flexible. Although it’s less likely to be damaged due to its enhanced flexibility, it can develop cracks with age.
Galvanized steel gas pipes are extremely durable and will not corrode. They’re also very energy efficient! However, the downside is they’re more expensive than other types of gas pipe materials that work just as well or better, mainly due to the labor-intensive installation process, which requires welding.
High-Density Polyethylene Piping (HDPE):
HDPE gas pipes are very flexible, durable, and do not corrode. They’re also resistant to punctures and cracks and can withstand higher pressure levels. The primary drawback of HDPE pipes is that underground tree roots or rocks can damage them.
The risk of natural disasters in Tampa and local safety code requirements will also influence what type of gas line you choose.
In the Tampa area, our coastal location, population, and topography make us more vulnerable to various types of natural disasters, including floods, tornadoes, and sinkholes. In fact, in November 2021, Center Square named Tampa one of the top U.S. cities most vulnerable to costly hurricane damage.
With this in mind, it’s a good idea to consider how well a gas line will hold up to natural hazards in our area. For example, contractors generally recommend CSST piping in areas with higher instances of natural disasters. However, an experienced contractor in the Tampa area can provide individualized recommendations based on local natural disaster risk profiles and safety code requirements.
Interior or Exterior Applications
Various types of gas pipe materials may last longer and perform better when installed indoors or outdoors.
For example, HDPE piping is one of the most highly recommended types of gas line for outdoor applications because it’s highly resistant to corrosion, punctures, and cracks and can withstand higher pressure levels. On the other hand, CSST piping may be a better option for indoor jobs since it’s very flexible and performs well in tight spaces.
A contractor should be able to tell you what type of gas pipe is best for your application, whether it’s an indoor or outdoor job.
