在海洋底下开采石油及天然气过程中,常常伴随H_2S,CO_2及氯等有害气体,另外海水等对钢材侵蚀非常历害,因此在石油工业中代替钢材及保护用化费达数十亿美元。由于玻璃钢等复合材料耐蚀性好,在深海开采石油方面的应用将有潜力,在深水中用作主结构设计将可减轻重量15%～20%。另外用玻璃钢等复合材料,其投资将减少,通常讲玻璃钢肯定比钢贵,但与其他耐腐材料比有竞争性。对管材及管道系统而言玻璃钢比碳钢贵1.5～2.5倍,但安装费用 In the process of oil and gas exploration under the ocean, it is often accompanied by harmful gases such as H 2 S, CO 2 and chlorine. In addition, seawater and other harmful effects on steel erosion have long been detrimental to billions of dollars in the oil industry. Due to the good corrosion resistance of FRP and other composite materials, the application of deep-sea oil exploration will have the potential. Using it as a main structural design in deep water will reduce the weight by 15% -20%. In addition with FRP and other composite materials, the investment will be reduced, usually speaking FRP is definitely more expensive than steel, but with other corrosion-resistant materials than competitive. For pipe and piping systems, FRP is 1.5 to 2.5 times more expensive than carbon steel, but at the expense of installation
