Gas Station Buried Pipeline Renovation

With China’s traffic network development, a petrol station more and more distribution along the roads in modern highway traffic network, become necessary in infrastructure. Gas station in the process of operation exposed all kinds of problems, not meet the actual needs or security the request of production, need improvement.This paper studied gas station in the process of reconstruction main links-buried process piping transformation. This article from the buried process piping materials, the oil form, corrosion protection, oil and gas recovery, engineering construction key link for research. Gas station buried process piping choose to use seamless steel tube, in steel have serious corrosion in the soil conditions of use oil resistance, resistance to erosion, conducting electrostatic composite pipe--PE complex pipe. Through the empirical formula to determine self-suction pump in positive pressure injection in length and oil pipeline way buried depth of the relationship. Use the equation (cypress to determine the diameter and length of the oil pipeline. Through to the self-suction pump fuel supply way and the potential negative pressure pump positive pressure injection way contrast determination by potential oil pump technology as a reform of the fuel gas station preferred way. And point out that the buried process piping in construction should be paid attention to. Through the analysis of the characteristics of gas station soil environment, the comparison in the actual construction process of found buried process pipeline corrosion, according to the site conditions, make sure to put outer protective layer to prevent buried pipeline corrosion of main methods. Through the contrast of anti-corrosion materials to select a proper epoxy coal pitch with cold bound for the long-distance buried pipeline.In addition, this paper also on the gas station at discharging oil link and fuel oil and gas loss is too big, to link environmental pollution is severe and body health effects to the worker, larger transformation in a gas station to the oil&gas recovery transformation.
