Classification Of Oil Pipelines In Pipeline Cleaning!
Group Cost of A Long-Distance Oil Pipeline
A long-distance oil pipeline includes two parts: an oil station and a pipeline.
Oil Station
The main function of the oil transportation station is to pressurize and heat the oil products. The oil transportation station at the starting point of the pipeline’s other name is the initial station. Which receives oil products from oil fields, Refineries, or ports. Then, it is transmitted to the next station after metering. During the transportation process, due to dirt or terrain height, the oil pressure drops continuously. Therefore, in the long-distance pipeline, it is necessary to set up an intermediate oil transfer pump station to pressurize the oil.
In addition, users also need to conduct regular pipe cleaning. For the pipeline heated for transmission, the temperature of oil products gradually drops during the transmission process. This requires an intermediate heating station to heat the oil. The oil pump station and heating station are set together, they are called heat pump stations. The oil transmission station at the end of the pipeline is” the terminal station”. Which receives the oil and gas from the pipeline. Then it is transferred to oil refineries, railways, and waterways. The terminal station has equipment such as many oil tanks and an accurate metering system.
Pipeline
The pipeline part of a long-distance oil pipeline includes the pipeline itself, valve chambers along the line, crossing structures through rivers, highways, and valleys, cathodic protection facilities, communication, automatic control lines, etc. Long-distance oil pipelines are welded by steel pipes and generally laid underground. This part is also the main part of pipeline cleaning.
To prevent the soil from corroding the steel pipes, the pipes are covered with an anti-corrosion insulation layer and protected by the electric method. Block valve chambers are set at intervals at both ends of long-distance oil pipelines and large crossing structures. Once an accident occurs, cutting off the oil in time in the pipeline can prevent the expansion of the accident and facilitate emergency repair. The communication system is an important facility for a long-distance oil pipeline. Which is used for the production scheduling of the whole line and the transmission of system monitoring information. The main communication modes include microwave, optical fiber, and satellite communication.
