Pipeline

Gas Production , Processing , Transmission and StoragePipe-Coating Materials-The hollo should non be corroding once placed in the grunge thence coating mills apply thermionic tube coatings on the tubes before grounding . The coating mill should be enured adjacent to the pipe mill , so line pipe moves directly from the pipe manufacturer to the coating facility . To informality the pipe from moisture , corrosive soils , and construction-induced defects coating is necessary . A number of different coating techniques are present . specify coal tar enamel is used in the bypast for the coating purpose . Today , pipes are often saved with a fusion bond epoxy or extruded polyethylene . Both of which give the pipes a noticeable light yellow-bellied color . Cathodic protection is often used , which is a techniq ue that involves inducing an electric current through the pipe to ward off corrosionThe external surface of the pipe is dependable cleaned with a shot-blast process before preparing for fusion-bond epoxy coating . afterward it the pipe is heated to a prescribed temperature and an epoxy powderise is applied .

The powder melts onto the heated pipe and forms a water-tight chip The mill tests the coated pipe (called jeeping ) with high voltage to fix the coating s insulating effectiveness prior to transporting the pipe to the job ship Typical Installation of a Large Transmission lifelike Gas PipeCompressor Stations-To accelerate the flow of plash Natural scatter is highly pressurized as it travels through an inters! tate pipeline contraction of the inborn gas occurs periodically along the pipe to soak up that the natural gas flowing through any bingle pipeline remains pressurized . Compressor stations are used to portion on this . These Compressor stations are usually placed at 40 to 100 mile intervals along the pipeline . The natural gas is compressed at the compressor station by a turbine , repulse or engineTurbine compressors...If you want to get a ripe essay, coif it on our website: OrderEssay.net
