Pipe bursting is a trenchless method of replacing buried pipelines (such as sewer, water, or natural gas pipes) without the need for a traditional construction trench. "Launching and receiving pits" replace the trench needed by conventional pipe-laying.
Legislation passed in 2014 [12] requires gas suppliers to make greater efforts to control some of the 20,000 documented leaks in the US state of Massachusetts. The new law requires grade 1 and 2 leaks to be repaired if the street above a gas pipe is dug up, and requires priority be given to leaks near schools.
Maximum Allowable Operating Pressure (MAOP) is a pressure limit set, usually by a government body, which applies to compressed gas pressure vessels, pipelines, and storage tanks. For pipelines, this value is derived from Barlow's Formula , which takes into account wall thickness, diameter, allowable stress (which is a function of the material ...
Natural gas (and similar gaseous fuels) are pressurized into liquids known as natural gas liquids (NGLs). [5] Natural gas pipelines are constructed of carbon steel. Hydrogen pipeline transport is the transportation of hydrogen through a pipe. Pipelines are one of the safest ways of transporting materials as compared to road or rail, and hence ...
Meanwhile, manufactured gas was more commonly used than natural gas in the early 19th century, first introduced in Baltimore in 1816 with underground pipes laid starting in 1851. [6] Gas plants could be sited within cities, and many major U.S. cities such as New York, Chicago, San Francisco had gas distribution lines for manufactured gas by the ...

The Federal Energy Regulatory Commission (FERC) is an independent agency of the United States government that regulates the interstate transmission and wholesale sale of electricity and natural gas and regulates the prices of interstate transport of petroleum by pipeline.
The flow of a gas or hydrocarbon liquid down a pipe line causes erosion as a result of the contact between the pipe wall and the medium being transported. The main factors that increase erosion are the flow rate and the contamination levels present in the gas or hydrocarbon fluid.
