Problems solved by technology
[0003] The exploitation of offshore oil requires the laying of oil pipelines on the seabed for oil transportation. Unlike land, submarine oil pipelines need to withstand huge water pressure and various conditions brought about by harsh environments. At present, in offshore oil exploitation, The annual repair and maintenance costs for submarine pipelines are huge, and when the pipelines are connected, the underwater operation time is too long, so it is necessary to design an oil transportation pipeline with strong pressure resistance, which can adapt to the harsh environment of the seabed and is easy to connect, and can be used for a long time Sometimes, due to special reasons such as artificial maintenance and installation of oil pipelines, or natural disasters, the flange connection is easy to be loosened due to external impact, and then the oil transportation works normally. Therefore, a petrochemical pipeline is proposed to solve the above problems

Description
technical field [0001] The invention relates to the field of petroleum transportation, in particular to a petrochemical transportation pipeline. Background technique [0002] Petroleum is one of the main objects of geological exploration. It is a viscous, dark brown liquid known as "industrial blood". There are oil reserves in some areas of the upper crust; the main components are various alkanes, naphthenes, and aromatic hydrocarbons The oil-forming mechanism of petroleum has two theories of biosedimentary oil and petrochemical oil. The former is more widely accepted. It is believed that oil is formed by organisms in ancient oceans or lakes after a long evolution. It belongs to biosedimentary oil and is non-renewable. The latter believes that oil is produced by the carbon in the earth's crust itself, which has nothing to do with biology and is renewable; the properties of oil vary according to the place of origin, the density is 0.8-1.0g / cm3, the viscosity range is very wid...
