Research Of Long Distance Oil Pipeline Leak Detection Technology

Along with the development of the western development, the long distance pipeline construction in Shan Bei region, this task significantly intensified, according to statistics, the total length of long distance pipeline around the world has reached 2 million kilometers, the total weight of buried pipeline steel is about 200 million tons, imagine if this part of the pipe in the construction of effective corrosion protection measures were not taken, calculated on corrosion of 10% a year, the amount of steel corrosion of 20 million tons, calculated at 5000 yuan per ton, the steel corrosion off each year up to 100 billion yuan, it has not been included because of the economic losses caused by the leakage of pipeline corrosion, so the long distance pipeline corresponding corrosion measures is an effective way to reduce the economic loss and quality safety accident.This article reviewed in recent years about the long-distance pipeline anticorrosion literature both at home and abroad, this paper expounds the mechanism of long distance pipeline corrosion, to Jingbian pipeline region soil measurement analysis, find out the factors that affect soil corrosion. To Jingbian pipeline area construction of long distance pipeline anticorrosion engineering measurement analysis, to Jingbian pipeline area after the construction of long-distance pipeline anticorrosion methods contrast analysis was made on the economy, the results showed that in Jingbian pipeline areas because of its high soil resistivity, the alkaline PH value, in the similar geological structure after the proposal of long pipeline, small diameter and short, can be cancelled to be the corrosion of sacrificial anode and impressed current method outside the pipeline anticorrosion coating way circuitry, it can effectively reduce the construction cost and maintenance debugging costs, save a lot of resources, to reduce the long-distance pipeline construction costs has certain reference significance.
