The average lifespan of a gas line can vary depending on several factors, including the type of material used, the service quality of the gas line installation expert you hired, and the maintenance it receives.
Making your gas lines at home last longer is possible if you know more about their materials and how to take better care of your gas lines through regular professional maintenance.

The Different Gas Line Materials and Their Lifespan
Steel Pipes
Steel pipes are durable for decades but corrode over time, especially without proper maintenance or if they are constantly exposed to moisture. They can last anywhere between 40 to 70 years.
Copper Pipes
Copper is less prone to corrosion than steel, but it is more prone to degradation, especially in acidic environments. Its average lifespan is roughly 20 to 50 years.
Flexible Corrugated Stainless Steel Tubing
CSST is flexible and easier to install, but professionals need to take the extra step of properly bonding and grounding it to prevent damage from lightning or electrical faults. With regular maintenance, CSST gas lines can last 30 to 50 years.
Polyethylene Pipes
PE pipes are commonly used for underground installations because they are resistant to corrosion and very durable. Compared to other gas line materials, polyethylene pipes last the longest and can outlast other materials, lasting up to 100 years.
In general, CSST is one of the best materials for gas lines in homes. It’s flexible, making it easier to install around bends and obstacles without requiring numerous fittings and joints. This flexibility also allows CSST to handle slight movements and shifts better, which often occur in Denver due to soil settlement or seismic activity.
What Factors Affect the Gas Line Lifespan?
Proper installation is the biggest factor affecting gas line lifespan. Poor installation by an unqualified professional often results in early failures and is a potential safety hazard. Only work with a certified professional when installing or increasing your gas line.
If your gas lines are properly installed, you should schedule regular inspections and maintenance to extend their lifespan. This allows gas professionals to check your gas lines for leaks and signs of corrosion and to see if the connections are properly maintained.
Finally, two underrated factors that can cause gas lines to wear prematurely and last fewer years are high usage and overloading. Using undersized piping can result in fluctuating pressures and overload, stressing the gas lines much more than they’re equipped to handle. This shortens their lifespan and puts your home at serious risk.
Make Your Gas Lines Last Longer With Professional Help
Working closely with gas installation professionals guarantees the lifespan of your gas line.
Trusted experts can check the proper sizing of your gas line so that it can handle all the cumulative demand of your current connected appliances and any future appliances you might want to install. Undersized lines are just as dangerous as poorly installed gas lines. They are prone to overstressing, premature wear, and leaks.
High-quality connections among properly sized gas lines help maintain the efficient operation of all gas appliances without overburdening the gas lines, mitigating the risk of leaks and extending their lifespan.
