What is a gas pipe system?

Gas pipes are a piping system in your home that is used to transport natural gas from the supply directly to the heating system. The system is composed of branch lines, which go to the individual appliances throughout the house. Bypass lines lead to drop lines, which are risers that fall to an appliance. The pipe inside the house is called a gas supply line or construction line.

The branches go to the individual devices. The bypass line terminates in a bypass line, which is a vertical pipe that descends to the apparatus from an aerial bypass line. This drop line is called a riser if it carries gas to an appliance from a bypass line below the appliance. Gas pipes refer to pipes that carry water heated in the boiler through your house to the radiators.

The gas pipeline is used to transport gas, which is needed for daily cooking and bathing. The pipeline consists of pipes, flanges, bolts, gaskets, valves, relief devices, fittings and the pressure-containing parts of other piping components. It also includes hangers and brackets and other equipment necessary to avoid overloading parts that contain pressure. It does not include supporting structures, such as building frames and studs or building foundations.

Natural gas goes from the main pipe to a home or business on what is called a service line. Typically, the natural gas company is responsible for maintaining and operating the pipeline and facilities up to the residential gas meter. All equipment and gas supply lines downstream of the residential meter are the responsibility of the customer. Pipes must not be installed in or through a duct or ventilation duct.

No hidden pipes will be installed in such partitions %26 concrete walls. Fittings in hidden locations will be limited to threading, welding or welding. Underground penetrations are prohibited in foundations below the level. Some jurisdictions that used very old codes had fuel gas and ventilation systems covered by several chapters of the old BOCA or Uniform Plumbing Code or Uniform Mechanical Code.

The piping upstream of the gas meter and the meter itself are usually the responsibility of the gas company. I have inquired about many combustible gas explosions where the purge operations were carried out on new pipes that had experienced a loss of odor due to the gas having been in the pipeline for an extended period of time. Natural gas moves through the transmission system at a speed of up to 30 miles per hour, so it takes several days for Texas gas to reach a utility reception point in the Northeast. For a given project, the design professional must first determine if one of the above combustible gases is available on site through a local utility company or gas service provider (several projects I have participated in) with used methane gas captured from wells drilled in landfills for operating electrical generators.

They chose to develop a standard route rather than focusing on the need for temperature limiting switches or flue gas temperature sensors for fuel gas appliances that want to use plastic combustion tubes. Propane is also a common fuel gas in rural areas where the gas supply is in liquid form; it evaporates in the piping system at lower pressures. When natural gas from a transmission pipeline reaches a local gas company, it usually passes through a gate station. Refer to the fuel gas appliance manufacturer's recommendations for the minimum and maximum gas pressures for proper operation of the equipment.

The National Combustible Gas Code is the oldest model fuel gas code and has been revised and renumbered for many years. I do not recommend the use of plastic pipes in equipment that burns fuel, unless the fuel gas appliance has a thermal limit switch or a flue gas temperature sensor integrated into the smoke outlet connection of the equipment. Before you have a contractor, do the installation of gas pipes at home, make sure they are using the correct type of gas pipes. Gas flowing from higher to lower pressure is the fundamental principle of the natural gas supply system.

Typically, natural gas is piped from gas fields to utilities in high-pressure pipelines that can see pressures in thousands of psi. The space between the %26 line and the gas pipe must be sealed to prevent any gas leakage from entering. The two model codes in the United States are the International Combustible Gas Code, administered by the International Code Council, and the National Combustible Gas Code NFPA 54. .
