玻璃钢储罐防雷技术探讨

DISCUSSION ON THE LIGHTNING PREVENTION TECHNIQUE OF GLASS FIBER REINFORCED PLASTICS TANK

玻璃钢储罐具有寿命长、防腐性能好、电绝缘性好、自重轻、易制作、易清洗、免维护和抗震等优点。立式玻璃钢储罐主要用于油田的原油存储、原油沉降和污水存储等。由于罐内储存液体的可燃性,当遭受雷击时,易产生火灾危险。目前有关玻璃钢储罐的雷电防护技术措施薄弱。通过对玻璃钢储罐防雷现状的调研及雷击危害分析,根据雷电防护理论,对玻璃钢储罐雷电防护技术进行探讨。

In recent years,glass fiber reinforced plastics is gradually popularized at oilfield because of its advantages of long life,good resistance to corrosion,good insulation property,low specific gravity,easy process,easy cleaning,free of maintenance and anti-seismic.Vertical glass fiber reinforced plastics tank is usually used as crude oil tank,crude oil precipitation tank,wastewater tank and so on.As the oil and gas stored in the tank is flammable,fire would easily occur when the tank is hit by lightning.At present,the lightning prevention technique of glass fiber reinforced plastics is weak.Based on lightning prevention theory,this paper makes a discussion on the lightning prevention technique of glass fiber reinforced plastics through investigation into the present situation of the lightning prevention of glass fiber reinforced plastics tank and analysis on the harm of lightning.
