Powering your property

Does your business or home have a gas line running from a meter or tank? Many commercial properties and homes use natural gas or propane gas for cooking, heating, and water heater. Especially in restaurants, it is the preferred way of cooking because it can be controlled better than electric burners and ovens. While there are many people that prefer to cook with electricity and heat their homes and water with electricity, there are just as many that prefer gas.

Some remote areas do not have access to natural gas, so they use propane gas that is delivered by trucks. Either way, natural or propane, for the gas to go from the source to the home or business, it runs through a gas line, then another gas line runs to the various places that need gas.

What is a gas line?

 A gas line is either a hose or pipe that connects a gas appliance to the main source of natural or propane gas for a commercial building or residence, including apartment buildings, offices buildings, or anywhere gas is needed. Both natural and propane use a gas line you can bury from the source of the gas to the home or structure. There is a gas line to the water heater, cook stove and oven, and furnace distribute that gas as needed, with the gas line and fittings for each connection.

There are also gas lines at gas stations that run from the gas pump to the vehicles as gas is pumped into the tanks. Within each vehicle, there is a gas line from the gas tank to the carburetor and motor to make that power the vehicle. For the purpose of this article, we’re are going to discuss structural gas line purposes and answer questions. 

Which pipe is best for gas lines?

There are several kinds of materials that are approved to use for a gas line. However, there are building codes within every city, county, or jurisdiction that define what is acceptable within their areas and the purpose of any gas line. Before installing or burying a gas line, verify this with the appropriate agency. The materials suitable for a gas line are:

  • Aluminum: All jurisdictions will approve the use of aluminum pipes for a gas line that is not going to be buried.
  • Copper: Type L or Type K copper piping is approved for use as a gas line.  
  • Ductile Iron: For gas line work underground, Ductile iron pipes are approved by some jurisdictions.
  • PE Pipes: PE (Polyethylene) can be used for outside gas lines.
  • PVC Pipes: PVC (Polyvinyl Chloride) can be used for outside gas lines.
  • Steel: If there isn’t any concern about corrosion from the environment, steel pipes make a suitable gas line and is one of the most common type of gas lines inside structures.
  • Yellow Brass: For interior gas line installation, yellow brass pipes are acceptable.

Along with these different types of materials for a gas line, there are flexible connectors to fit each one that is used for connecting any appliances to the gas source. You should verify that the flexible connector chosen is approved for the intended purpose. 

Can PEX be used for gas line?

There is a PEX pipe that can be used for a gas line. It is a composite of aluminum/plastic and if five layers called Pex-Al-Pex Pipe G-Pex. This pipe consists of a welded aluminum layers inner and outer made of polyethylene and bonded together with a special adhesive that is hot melted. The gas line approved PEX is red.

What are residential gas lines made of?

For natural gas, black metal pipe was the only choice available. Today, jurisdictions and municipalities allow several alternative pipe materials for gas line plumbing, in lightweight metals or plastics.  

In most homes today, corrugated stainless steel tubing, a flexible pipe is used to connect appliances to the rigid gas lines that come from the supply source.  High – density polyethylene, a plastic material, comes in large spools and is usually used by contractors for whole-house gas line plumbing if the local jurisdiction allows it. Typically, this gas line pipe material is reserved for commercial and industrial applications. Some jurisdictions approve using it in residential gas line installation.

Black iron pipe, the traditional original for natural gas line plumbing, is still around and worth its difficulty to install. The supply of natural gas is safely encased within the thick-walled pipe. A black iron pipe that may be exposed to moisture can corrode and rust.

How deep should a gas line be?

This can vary based on where you’re located, to be certain you’re burying any of your uses to meet the jurisdiction requirement and call the local government offices. The climate can dictate the depth of waterlines, typically is a 24” minimum of 24″ so it is below the freeze line.

It is rare to find a gas line frozen because it doesn’t freeze the same as water pipes. Other factors that can determine the depth is your landscaping. This can change the slope, which can affect your sewer lines. Natural gas line service to a residence is 18″ to 36″ and the gas main is 24″ to 48″.
