Pipeline project means construction of transportation of oil, natural gas and solid slurry pipeline project. Including pipeline line project, the library works and pipeline stations ancillary works. Pipeline project in the broad sense also includes equipment and supplies. Pipe line project with pipes, fittings, valves and other piping connections starting point, intermediate stations and terminals, pipeline transportation lines constitute the project. Is the main part of the pipeline project.

Features of pipeline project

① comprehensive and strong

Pipeline Engineering is the application of a variety of modern science and technology, integrated project, which includes a number of general construction and installation works, including some with professional engineering and construction, professional equipment and construction technology. A pipeline as well as hundreds of tons of steel consuming millions of tons, and sometimes need to invest billions of dollars, a mammoth project is seen as a large, integrated industrial construction projects around the world.

② high complexity

Large oil and gas pipelines are often thousands of kilometers long, along may have to climb high mountains, crossing rivers Innovative, or extremely difficult to pass through the marshes, and some must pass through the desert. Especially since the 1970s, gradually extending into the Arctic pipeline project and the plateau permafrost zone, and to particularly complex deepwater development project conditions. In addition, the pipeline project is closely related to the urban and rural construction by region, water resources planning, energy supply, integrated transport, environmental protection and ecological balance problems, and, in the construction of thousands of kilometers of line construction organizations, the need to address a large number of temporary problems, such as supplies, transportation vehicles, roads, water, electricity, communications, construction, pipe prefabrication plant and livelihood security, all of which make the pipeline project is more complex.

③ highly technical

Pipeline project is highly technical modern engineering. The pipe itself and the equipment used, be able to ensure a higher pressure, safety, continuous transport flammable gas oil. Working pressure onshore pipelines and some up to 80 kgf / cm 2 or more, the performance of marine pipelines under pressure even up to 140 kgf / cm 2. In addition, various properties of different oil and gas, to make pipeline transportation technology to meet different requirements. Such as natural gas and crude oil pipeline to carry gas desulfurization or dehydration pretreatment, viscous crude oil pipeline transportation and easy to pour heated or heat treatment. Pipeline was applied on environment vary widely, but also targeted disposal measures, such as insulation permafrost areas, sand fixing desert region, through or across a large river, deep underwater stable tubes. These technical issues are very complex and require a multi-disciplinary, multi-disciplinary to integrated solutions. Modern plumbing wider use of electronic technology, with a high level of automation in the management, centralized control, and efficient and reliable management of its more technical.

④ high stringency

Pipeline project must strictly meet the requirements of the quality of the design and specifications. Thousands of kilometers of pipeline systems, often under conditions of changing conditions, to long-term, efficient and safe continuous operation, the pipeline would require at any time in the best running condition.
