What do pipeline transportation projects include?

Pipeline Construction Construction of pipelines transporting petroleum products, natural gas and solid slurries. Including pipeline engineering, station warehouse engineering and pipeline ancillary engineering. In a broad sense, pipeline engineering also includes the supply of equipment and equipment.

Pipeline transportation projects include

①Pipe body engineering

That is, a project that is welded into a whole by pipes and pipe fittings. Pipeline line engineering is a project that uses pipes, pipe fittings, valves, etc. to connect the starting station, intermediate station and terminal station of the pipeline to form a pipeline transmission line.

②Pipeline protective structure engineering

Including pipeline internal and external wall anti-corrosion, pipeline insulation and other projects. The commonly used method for pipeline anti-corrosion is coating anti-corrosion plus cathodic protection.

③Pipeline crossing project

This includes projects that cross railways, highways, rivers and canyons, tunnels that cross mountains and ridges, and projects that cross unfavorable geological areas.

④ Line supporting projects

Including branch lines, pipeline valve facilities for reserved lines, emergency shut-off valve devices, pipeline exhaust or drainage facilities, pipeline detection instruments, line protection and pipeline stabilization structures, ground pipeline support structures, line signs, etc. The process starts with line selection, that is, determining the basic direction of the pipeline from the starting point to the end point, that is, determining the plane position of the pipeline. Then conduct geological, hydrological survey and topographic survey, and conduct line design on this basis; carry out construction according to the design. Buried pipeline construction procedures include line development, pipeline pretreatment, trenching, pipeline transportation and layout, pipe bending and assembly, welding, quality inspection, pressure testing, trenching, backfilling, terrain restoration, sign setting, etc.

Warm reminder: Most of the petroleum casing used in pipeline transportation are seamless pipes（https://www.eastern-steels.com/product/seamless-steel-pipe.html）, spiral submerged arc welded pipes, etc.
