【摘要】：随着国家对绿色新兴能源应用的大力推广,近两年中国天然气尤其是LNG市场呈爆发式增长,直接导致对LNG储罐等深冷容器的旺盛需求。因LNG储罐制造门槛不是很高,很多传统压力容器生产企业纷纷介入LNG储罐的生产制造,市场竞争非常激烈,成本压力凸显,仅依靠生产过程中的精细化成本控制已不能满足市场竞争的需要。LNG储罐由内外筒组成,按照常规设计,仅内筒体所用奥氏体不锈钢板材料费就占据整台储罐成本的35%,所以在满足安全性能的前提下,关键是实现内筒轻量化。而采用室温应变强化技术是近年应用在奥氏体不锈钢板提高屈服强度、减薄壁厚、降低成本、增强市场竞争力的最有效手段之一。然而,应变强化技术的应用是一个复杂的过程。应变强化技术在国外应用虽然日趋成熟,但国内应用该技术尚处于起步阶段,案例不多,尤其是应用应变强化技术前后对LNG储罐成本具体影响的研究也较少。本文将结合该技术首次在XX公司60m3LNG储罐项目上的实际应用,通过对应用该技术前后的实际成本进行比较分析,探讨该技术在成本管理控制上所起到的积极作用,以及应用过程中出现的障碍与问题,然后提出改进措施和注意事项,为该技术在其它类似产品项目管理上的应用起到降低成本的积极引导作用,有助于提高企业绩效和市场竞争力,并为实施该技术企业的成本管理控制提供参考和借鉴。
[Abstract]:With the promotion of green and emerging energy application, the natural gas market in China, especially the LNG market, has been exploding in the past two years. Because the manufacturing threshold of LNG storage tanks is not very high, many traditional pressure vessel manufacturers have been involved in the production and manufacture of LNG storage tanks. The market competition is very intense, the cost pressure is prominent, only rely on the fine cost control in the production process can not meet the needs of the market competition. LNG storage tank is composed of inner and outer barrel, according to the conventional design. The material cost of austenitic stainless steel plate used in the inner cylinder alone accounts for 35% of the cost of the whole tank, so the safety performance is satisfied. The key is to lighten the inner cylinder, and the room temperature strain strengthening technique is used in recent years to improve the yield strength, reduce the thickness of the wall and reduce the cost of austenitic stainless steel plate. One of the most effective means to enhance market competitiveness. However, the application of strain strengthening technology is a complex process. Strain strengthening technology is becoming more and more mature in foreign countries. However, the domestic application of the technology is still in its infancy, and there are few cases. Especially the application of strain strengthening technology before and after the specific research on the cost of LNG storage tank is less. This paper will be combined with this technology in XX company 60m3 LNG tank project practical application for the first time. Through the comparative analysis of the actual cost before and after the application of the technology, this paper discusses the positive role of the technology in cost management and control, as well as the obstacles and problems in the process of application. Then put forward the improvement measures and points for attention for the application of this technology in other similar products project management to play an active role in reducing costs to help improve enterprise performance and market competitiveness. And provides the reference and the reference for the implementation of the technology enterprise cost management control.
