[优秀毕业设计精品] LNG市场及其储罐的技术现状和发展方向.doc

摘要 本次设计主要从安全、经济的角度进行LNG港口接收站的系统设计，并通过计算和取材进行LNG储罐的结构设计；并结合制造、维护等工艺要求进行LNG储罐的施工建造流程设计和罐壁的焊接工艺设计；不仅使制造工艺简单；而且操作使用方便。本设计的20万立方米大型储罐尽量遵循有关国家标准及部颁标准；严格规范；力求做到设计合理；确保使用安全。本次设计对比了两种建造方案，并选择了最优的一种。并且在关键问题处理上取得了突破。 关键词： LNG站 大型 储罐 焊接 ABSTRACT This design mainly from the security, economic perspective LNG port terminal of the system design, calculation and drawn for by the structural design of LNG storage tanks; and the combination of manufacturing, maintenance and other technical requirements for the construction of LNG storage tank design and construction process tank wall welding technology; not only the manufacturing process is simple; and easy to operate. The design of the 200,000 cubic meters of large storage tanks as far as possible follow the relevant national standards and ministerial standards; strict norms; tried to be designed; to ensure safe use. This design compares two kinds of construction programs. And select the best one. And key issues in the handling of a breakthrough.
