Natural gas pipeline construction

What is in a natural gas pipeline?

Oil pipelines are made from steel or plastic tubes which are usually buried. The oil is moved through the pipelines by pump stations along the pipeline . Natural gas (and similar gaseous fuels) are pressurized into liquids known as Natural Gas Liquids (NGLs). Natural gas pipelines are constructed of carbon steel.

How does a natural gas pipeline work?

Natural gas that is transported through interstate pipelines travels at high pressure in the pipeline, at pressures anywhere from 200 to 1500 pounds per square inch (psi). This reduces the volume of the natural gas being transported (by up to 600 times), as well as propelling natural gas through the pipeline.

How close can you build to a natural gas line?

50 feet

What is stringing in pipeline construction?

STRINGING : Pipe is transported in to the easement and laid end to end next to where the trench will be dug. 5. BENDING: Where required, specialized machinery is used to bend the pipe to conform with the contours of the land and the pipeline route.

How fast does natural gas flow in a pipeline?

Pumping through the transmission lines Large compressors similar to jet engines (with up to 36,000 horsepower) move natural gas through the pipeline at around 40 km an hour. The compressor station and pipeline form a fully enclosed system so natural gas does not escape.

What is the largest natural gas pipeline?


What are the 3 biggest uses of natural gas?

Natural gas is a fossil fuel . Natural gas is a non-renewable hydrocarbon used as a source of energy for heating, cooking, and electricity generation. It is also used as a fuel for vehicles and as a chemical feedstock in the manufacture of plastics and other commercially important organic chemicals.

How many PSI is a natural gas line?

The natural gas pressure of the gas line leading to the home ranges from approximately 1/4 psi to 60 psi , depending on the number of homes or businesses served by the line . This compares to pressures of up to 1,500 psi for large-volume pipelines used to move the gas from the well fields to the local utilities.

Are natural gas pipelines safe?

According to the U.S. Department of Transportation, pipelines are the safest , most reliable and cost effective means of transporting energy products, such as natural gas , over long distances.

Is it dangerous to live near a gas pipeline?

In general, gas lines are much less susceptible to failure than, for example, aging water pipes . But when something does go wrong, the damage can be far greater than flooded streets and homes. Over the years, pipeline breaks have killed dozens of people and resulted in millions of dollars in damage to property.

Can you build a house over a gas line?

There are provisions in the Gas Safety (Installation and Use) Regulations 1998 (regulation 19), which include provisions that persons may not install gas pipes under buildings. There are however no provisions which deal conversely, with people not erecting buildings over existing gas service pipes .

Can you dig around a gas line?

Gas lines are typically metal or plastic. If plastic, they ‘re very likely thick enough to withstand most hand digging with a shovel. Laws typically require hand digging within some distance (18″ in my state) of a marked line .

How dangerous is pipeline work?

For the last 10 years, oil and gas extraction workers have had one of the highest fatality rates in the nation. In 2016, pipeline construction workers died on the job 3.6 times more often than the average American worker.

What are the different types of pipelines?

Types of Oil and Gas Pipelines Petroleum pipelines transport crude oil or natural gas liquids, and there are three main types of petroleum pipelines involved in this process: gathering systems, crude oil pipeline systems, and refined products pipelines systems.

What is row in pipeline?

A pipeline right-of-way ( ROW ) is property in which a pipeline company and a landowner both have a legal interest. Each has a right to be there, although each has a different type of use for the land. A pipeline requires regular observation, integrity assessment and maintenance to maintain the safety of its operations.
