Pipeline transportation engineering Construction of pipelines for transporting oil products, natural gas and solid slurry. Including pipeline line engineering, station depot engineering and pipeline ancillary engineering. In a broad sense, pipeline engineering also includes the supply of equipment and equipment.
Pipeline transportation projects include
①Pipeline 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 transportation line.
②Pipeline protection structure engineering
Including pipeline inner and outer wall anticorrosion, pipeline insulation and other projects. The common method of pipeline anticorrosion is coating anticorrosion plus cathodic protection.
③Pipeline crossing project
Including projects crossing railways and highways, projects crossing rivers and canyons, tunnel projects crossing mountains, projects crossing unfavorable geological areas, etc.
④ Line ancillary works
Including branch lines, pipeline valve facilities for reserved lines, emergency cut-off valve devices, pipeline exhaust or liquid drainage facilities, pipeline line inspection instruments, line protection and pipe stabilization structures, ground-mounted pipeline support structures, line signs, etc. The construction procedure of the pipeline line engineering is to select the route first, that is to determine the basic direction of the pipeline from the starting point to the end point, that is, to determine the plane position of the pipeline. Then carry out geological, hydrological survey and topographic survey, etc., and design the line on this basis; carry out construction according to the design. The construction procedures for buried pipelines include line development, pipe pre-processing, trenching, pipe transportation and layout, pipe bending and assembly, welding, quality inspection, pressure testing, trenching, backfilling, landform restoration, and sign setting.
Tips: The octg pipes used for pipeline transportation are mostly seamless pipes, SSAW pipes, etc.
