How To Run Natural Gas Line Underground


How deep do you need to bury natural gas lines?

All trenches must be 24” deep the entire length and level at all riser locations with no rocks or debris that can damage the pipe in any way. When back-filling, be sure to use clean back-fill material. Under certain conditions, the gas line must be installed in a sleeve for additional protection. via

Can you direct bury flexible gas line?

Can it be buried? Yes, however it must be sleeved in a non-metallic conduit ½” larger than the pipe. HOME-FLEX CSST has been tested and certified by CSA and IAPMO for compliance with the industry standard ANSI LC-1 / CSA 6.26, “Fuel Gas Piping Systems using Corrugated Stainless Steel Tubing (CSST).” via

Can I bury copper gas line?

In most cases, the best option for installing copper underground is to bury it in direct contact with the soil. Copper is naturally corrosion resistant to most soils and underground environments. via

How do you run a gas line through an outside wall?

Drill a hole through the house wall using a drill bit long enough to pass all the way through the wall. Drill bits of this size can be rented at most tool rental businesses. Position the hole as close to the appliance that will be using the propane as possible, so most of the pipe run is outside rather than inside. via

The most common and cost-effective product used for underground gas piping applications is polyethylene tubing. via

    How deep are water mains buried?

    Exterior piping may be either buried or installed aboveground and shall be well supported and protected against mechanical damage. Underground piping shall be buried not less than 18 inches below the surface of the ground unless otherwise protected. via

    How do you keep natural gas lines from freezing?

    The best way to prevent freezing is by dehydration, the removal of water from the gas stream. Simply stated, with no water, there is no freezing. One way to remove water is through glycol absorption. As gas passes through the glycol inside a contactor, the glycol meets up with a mixture of water vapor and hydrocarbons. via

    What material is used for underground gas lines?

    Piping materials

    Steel, copper, brass: The most common gas piping is black steel. Galvanized steel, copper, brass or CSST (Corrugated Stainless Steel Tubing) also can be used in some areas, but some utilities specifically prohibit the use of copper. In other areas, the use of copper is widespread. via

    Can you run electrical wire next to gas line?

    When running through conduits, it is recommended that you extend electrical wires separately, especially from water and gas lines. On their own, they present no threat. However, if they become exposed and come in contact with one another, the results can be rather devastating. via

    Can a flexible gas line go through a wall?

    CSST is flexible, so it easily snakes through walls and around obstacles without the need for multiple joints. With rigid pipe, routing around each obstacle requires a joint that needs to be fitted and checked for leaks. With CSST, fittings are only needed at the ends of each run. via
