In 1914, drew the first 9 km long oil pipeline in the central United States built, from industrial development pipeline. Be used to liquid or gas pipeline, the cost of rail transport by 1 / 3, the sea transport of 2 / 3, so the last few years saw rapid development of transportation. Well known that long-distance pipeline pipeline, long-distance pipeline valves for the call, check that valves, a ball valve, gate valve, valves, plug valves use a pipeline to meet the special requirements with special features special valve. Ball claims that the pipeline for the ball. Standard ball valve technology standards of the American Petroleum Institute API Specification 6D "oil and gas industries - Pipeline Transportation - Pipeline valves" issued in January 2000, the latest version of the 22 Edition issued in 1999 and awarded with the international standard ISO14313-1999.

　　Indeed, the rapid development of the pipeline industry, something the 1950 is under the "Pipeline" magazine in 2000, statistics has built the world's 2.6 million km long pipeline has been, of which 800,000 km oil pipeline, pipeline 1, 4 million km, the other petrochemical products pipelines 400.000 km. Oil pipeline is an energy supply is a vital artery has, is all over the world, and 30,000 km per year is still increasing. The maximum sound pressure level pipeline valve PN42.0Mpa (Class2500), the maximum diameter 60 inch valve (DN1500).

　　The world's leading long-distance pipelines, such as the U.S. east coast from Alaska to the Atlantic Ocean oil pipeline, Long Iceland, wetlands in the Arctic permafrost and the United States Great Lakes, the Russian Trans-Siberian oil pipeline to the Mediterranean region from Algeria to Spain via Morocco gas pipeline, with a total length of 2,000 km through the desert, the Atlas Mountains and the Strait of Gibraltar, in Southeast Asia through Malaysia from the Philippines, Java, Sumatra, at a total length of 6276 km long gas pipeline in Thailand, of which 1094 km undersea gas pipelines, and so on.

　　Been valve structure can back be traced back to 1904, applied for the structure of the patent, but not yet commercialized, its development is also something the 1950s, this is because the United States in 1943 the invention of DuPont Teflon plastic, this material has a certain flexibility, self-lubricating properties, good corrosion resistance, very good as a valve seal. And vehicle ball machine, ball machine of progress. This valve is full bore, a low flow resistance, is suitable as a remote pipeline valve, pipeline ball valve, the valve was replaced gradually by the pipeline, plug, is a nearly 50 years, the fastest growing valve new varieties.
