What are the characteristics of the oil casing industry?[Jul 21st, 2022]
Nowadays, the domestic oil pipeline construction is in full swing, but the current large oil pipeline length is only 35,000 kilometers. Professionals estimate that in the next 10 years, China will carry out the transportation of gas oil, diesel oil, kerosene and other formed product oil casing. To accomplish the above goals, an average of 20,000 kilometers of various transportation pipelines should be created each year. The construction of domestic oil pipelines will enter a new momentum, and will reflect the following characteristics:
Transition to large-diameter and high-pressure pipelines: When other standards are basically the same, the cost of pipeline transportation will be reduced with the expansion of pipelines. Under the standard of excellent crude oil resources and guaranteed oil sources, the benefits of building large caliber oil casing will be more obvious. To increase the pressure of pipeline operation, why not increase the transmission volume, expand the station interval, reduce the number of stations, so as to reduce the investment and cost. Therefore, the use of large diameter, high pressure transport is the trend of pipe network engineering transformation. At present, the maximum longitude of crude oil pipeline in China is 720mm, such as Luning line, while the maximum longitude of overseas pipeline is 1220mm. At present, the largest direct passage of natural gas pipelines in China is the west-east gas pipeline, with a direct passage of 1016mm, while the maximum passage of overseas gas pipelines has reached more than 1400mm. In China, there is still a big difference in the diameter and pressure difference of pipeline construction compared with the world standard.
Adopt pipe fittings with high hardness, toughness and good malleability; High intelligent pipeline operation. The above is the field characteristics of oil pipelines, welcome to come to consult.
