Compressed Natural Gas (CNG) refers to gaseous natural gas compressed to a pressure greater than or equal to 10 MPa and no greater than 25 MPa. The natural gas is pressurized and stored in a gaseous state in a container. CNG Pipe refers to a pipeline that transports compressed natural gas (including associated gas produced in oil fields) from a mining site or processing plant to an urban gas distribution center or industrial enterprise user, also known as a gas pipeline.
Using natural gas pipelines to transport natural gas is a way to transport large amounts of natural gas on land. Natural gas pipelines account for about half of the total pipeline length in the world.
Compressed natural gas is an ideal alternative energy source for vehicles, and its application technology has become increasingly mature after decades of development. It has the characteristics of low cost, high efficiency, no pollution, safe and convenient use, etc., and it is increasingly showing strong development potential. Natural gas filling stations are generally divided into three basic types, namely fast filling type, normal (slow speed) filling and a mixed type of the two.
Compressed natural gas is also used in urban gas business, especially as a fuel for residents' daily life. With the improvement of people's living standards and the enhancement of environmental protection awareness, the demand for natural gas in most cities has increased significantly. The economic benefit of natural gas (pipeline natural gas) as a civil fuel is also greater than that of industrial fuel.
CNG Pipe transportation has the advantages of low transportation cost, small land occupation, fast construction, large oil and gas transportation volume, high safety performance, low transportation loss, no "three wastes" emissions, low risk of leakage, low environmental pollution, and low impact on harsh weather , Equipment maintenance is small, easy to manage, easy to achieve remote centralized monitoring and other advantages.
