As the main force of long distance pipeline, what is the difference between oil pipeline and gas pipeline? Oil pipeline we are given priority to with common crude oil pipeline.

1. Different power sources: the same need for energy, crude oil pipeline and natural gas pipeline power sources are different. The power source of crude oil pipeline is centrifugal pump, and the power source of natural gas pipeline is compressor.

2. The temperature requirements are different: the same is the transmission; crude oil pipeline and natural gas pipeline on the temperature requirements are different, one to heat the other to cool. The freezing point of domestic crude oil transported by crude oil pipeline is generally higher, while the lower the temperature of natural gas pipeline is, the more convenient to transport.

3. Different flow velocity requirements: the same flow, crude oil pipeline and natural gas pipeline convection speed requirements are different; one is faster than the other is slower. Crude oil pipeline will set the volume; natural gas pipeline does not have low volume related problems.

4. Different rules of pressure drop: Due to the existence of friction resistance, energy loss occurs in the process of oil and gas pipeline transportation, and the pressure decreases with the increase of transportation distance. The pressure drop range of crude oil pipeline is more uniform, and the pressure drop of natural gas pipeline is generally slow first and then fast.

5. Different modes of distribution and transportation: crude oil pipeline and natural gas pipeline have similar resource sites, but the downstream users are very different, one is wholesale and the other is retail. Crude oil pipelines transport crude oil from oil fields to refineries, and natural gas pipelines can be distributed in any city along the pipeline.

6. Different compatibility: after the completion of crude oil pipeline and natural gas pipeline, the compatibility of other resources is different, one is picky and the other is tolerant. Crude oil pipeline is tailored according to the physical properties of oil, while natural gas pipeline has strong compatibility with different resources.

7. Different stability: crude oil pipeline and natural gas pipeline transport stability is different, a stable and a fluctuation. Upstream of the crude oil pipeline is the oil field, downstream is the refinery, are not affected by the season. The corresponding gas source of natural gas pipeline is relatively stable, while the demand of downstream market changes greatly.

8. Different environmental impacts: In the process of pipeline construction, it is inevitable to pass through various environmentally sensitive areas, but the impact of crude oil pipeline and natural gas pipeline on the environment is different, one is serious, the other is slight. Once the crude oil pipeline leakage, light will cause environmental pollution, serious will cause fire, the consequences are very serious. Even if there is a leakage accident in the natural gas pipeline, the valve chamber at both ends of the leakage point will be automatically shut off, and the gas stored in this section of the pipe will be quickly emptied, causing relatively little impact on the surrounding environment.
