Difference between oil pipeline and natural gas pipeline
The pipeline varies according to the transportation medium,and the requirements for some parameters are different. Only by understanding their differences can we produce pipes with different parameters according to different needs. Now let’s take a look at the main differences between oil pipelines and natural gas pipelines.
Difference in temperature: oil needs to be heated for transportation, which is generally heated to 70°C for outgoing and 33°C for downstream incoming.As for the gas, the lower the temperature of natural gas is, the better it is for transportation. Therefore, in the compressor station with higher outlet temperature, an air cooler should be set at the outlet to reduce the temperature.
Different flow rates: the speed of oil transportation is required to be fast, while that of natural gas is required to be slow. Because if the flow rate of natural gas is too fast, the friction between the natural gas and the pipe wall will increase significantly, and the vibration of the pipeline within the allowable stress range will increase, and the service life and operation safety of the pipeline will be affected.
Different compatibility: The oil pipeline is customized according to the physical properties of crude oil. Different oil sources have great differences in viscosity, freezing point, density, etc., so the compatibility of the crude oil pipeline with other resources is poor after the completion of the pipeline. The natural gas pipeline has strong compatibility with different resources, and it can basically be transported regardless of the gas source.
According to these obvious differences, there are different requirements for the internal and external surface treatment, strength parameters and other data of the pipeline. As an enterprise specializing in supporting products for pipeline engineering, Haihao Group can manufacture pipes of different specifications for different needs. Other accessories such as flanges, elbows, tees, valves, etc. can be customized by Haihao. We also support prefabrication. If you need pipeline products, no matter what scenes they are used for, Haihao has corresponding products for you.
