Short-distance and long distance pipeline, no matter seamless steel pipe for oil and gas transportation, or welded one for water transportation, would have great difference on choosing.

To some extent, working pressure and diameter would decide the pipeline’s design of framework technical parameters.

First of all, working pressure directly determines the number of pumping stations and compressor stations, steel consumption in the power station unit and piping.

Working pressure on the economy and security of the pipeline project is the first. Working pressure is an important part of the design of oil and gas pipelines, the technical and economic conditions of its great influence on the pipeline, the pipeline operating pressure is not too high; optimum working pressure gas pipeline and gas pipeline construction investment and operating costs related to; generally, the high pressure tends to work best value.
