The computer monitors the pressure, flow rates, and other parameters at various locations along the pipe. It also performs many on-line com- putations and sends commands to the field to control the operation of the valves and pumps. Manual intervention is frequently needed to modify the automatic operations, as when tanks, or when different batches of fuels are directed to different temporary storage the system must be shut down or restarted. 
Pipeline components. A pipeline is a system that consists of pipes, fittings, pumps for oil pipelines or compressors for gas pipelines, booster stations, stor- age facilities connected to the pipe, intake and outlet structures, flowmeters and automatic control equipment (computers). Booster stations are needed only for long pipelines that require more than one pumping station. The distance between booster stations for large pipelines is on the order of 50 miles.
Pipeline Network Composition. A pipeline network consists of various parts oil, gas or products through them from location to location. delivery network is the initial injection station. This is that work together to move oil and gas products. The starting point of a pipeline delivery network is the initial injection station where the product is fed into the pipeline system, which has comprehensive facilities attached to the storage tanks of the plant. The flow of products throughout the pipeline is regu- lated so that safe product supplies are ensured. A smooth product flow is maintained by compressors or pumping stations. These facilities are stationed at regular intervals along the network based on terrain topography, nature of the products transported and other operational requirements. Partial delivery stations, known also as intermediate stations, allow the pipeline operator to deliver part of the product being transported. Block valve stations are necessary to protect and maintain the pipelines with these valves, the operator can isolate any segment of the pipeline for maintenance work (e.g., to isolate a rupture or leak). Pipeline block valve stations are usually located every 30 to 50 km. the location depends on the nature of the product being transported, the trajectory of the pipeline and the operational conditions. Final delivery station, known also as outlet station, or terminal, - this is where the product will be distributed to the consumer it could be a tank terminal for liquid pipelines or a connection to a distribution network for gas pipelines.
Various technologies and strategies are implemented for operating and monitoring pipelines, from physically walking the lines to satellite surveillance. Through the advanced techniques pipeline operators watch the rate, pressure and pipeline use of movement of products. Pipeline maintenance crews work to ensure the integrity of pipeline infrastructure. They make sure that welding operations, valve inspections, pipeline repairs, corrosion prevention system checks and electronic equipment maintenance are performed safely and according to pre-established procedures.
