摘　　要：我国用9Ni钢已建投运的LNG接收站20余座,近百台储罐。北京燃气天津调峰站用法国GTT技术,拟建8台以上22~27万m 3的LNG薄膜罐,单台罐不锈钢的用量约为同等规模9Ni钢用量的十分之一,焊接材料数量和价格同比大幅减少,对用9Ni建造LNG储罐形成巨大挑战。本文重点对薄膜罐与9%镍钢全容罐技术应用进行了对比分析。China has more than 20 LNG Receiving Stations with totally about 100 tanks built with 9Ni steel under operation.Tianjin Peak Regulating Station of Beijing Gas Co.,Ltd.intends to build more than eight LNG membrane tanks of 220,000-270,000 m 3 each using French GTT technology.The consumption of stainless steel for a single tank is about one tenth of that of 9Ni steel of the same size,and the quantity and price of welding materials are greatly reduced.It is a great challenge for building LNG storage tanks with 9Ni steel.In this paper,the comparison between application of membrane tank and 9%nickel steel full containment tank technology is analyzed.
