Oil and gas pipeline

Views: 4    

Oil and gas pipeline measures 14 to 42 inches in diameter, but is usually 20 to 36 inches. It is often composed of 40-foot lengths but lengths may be as long as 60 or 80 feet. The pipe is wrapped and coated for protection against corrosion, especially since it runs underground. About half of all gas and oil is moved by pipeline.

Oil and gas from its source to a refinery and then from a refinery to the people who use the gasoline and other products made there is with a pipeline. Made from steel or plastic tubes, a pipeline can be as short as the length from a production facility to a nearby storage tank or as long as several thousand kilometres.

Pipelines may also be used to get oil or gas from its source to a terminal, a special facility where ocean-going tankers fill up for their journeys across open waters.

Pipelines can be built above land, under land or under water. When a pipeline runs through an environmentally sensitive area or close to a city or town, burying it is one way to minimize the likelihood and impact of potential accidents.

General technical requirements of the oil and natural gas pipelines are mainly three points, the necessary strength, stiffness, impact toughness and weldability, due to the transmission medium - oil and gas is not the same, as well as natural gas rich gas and used purifiedthe difference between natural gas, as well as conveying the lot (different section of the river crossing and overland conveyor section (there is one, two, three, four regions) and undersea conveyor section), different technical requirements of the steel pipe.
