Most Edmonton homes are fitted with gas lines. Natural gas fulfills about 1/4th your household’s energy requirements. However, most homeowners don’t have much information about gas lines and how they work. Ideally natural gas travels from the wellhead to your house through a series of pipelines. These pipelines are known as –
- Flow lines
- Gathering lines
- Transmission lines
- Distribution lines
- Service lines
Each of them carries natural gas at different pressures. The higher the pressure of gas in a pipeline, the more dangerous repercussion it may have if there is a problem.
If you suspect a problem in your gas piping immediately call emergency services. It’s important to understand each of the gas lines in further detail.
Flow lines move gas from the wellhead to a nearby storage tank. They carry raw un-odorized gas. Flow lines are relatively narrow compared to other pipes and are 4 feet below the ground. They are often at risk of corrosion from carrying wet gas.
Gathering lines collect gas from multiple lines and transport it to a centralized processing unit. They carry the same gas as flow lines and are also located underground but are a bit larger in diameter compared to flow lines. They too have a tendency to corrode due to the material they carry.
Transmission lines carry compressed natural gas from compressor to distribution facility. They travel long distances sometimes even inter states. These pipes are very large and carry gas in very high pressure. They can fail due to corrosion or defective welding.
Distribution lines are also known as mains. These pipelines are a link between high pressured transmission lines and low pressure service lines. They are medium sized and operate with a pressure lower than their carrying capacity. They contain odorized gas which reaches your house meter.
Service Lines are connected to the meter and supply natural gas to your house. They are narrow and carry low pressure odorized gas. Did you know that the pungent smell is added to the gas before distribution for your safety? They are usually made of plastic, steel or copper.
Maintaining gas lines is a very serious business. A small leak can put your family in jeopardy. Natural gas lines should be only handled by certified plumbers. Don’t trust some novice to save a few bucks, and absolutely never try any DIY things on gas lines – you don’t want to take that risk.
