摘要
在温室气体减排背景下,液化天然气(LNG)作为船用燃料和海运货物的市场规模不断扩大。LNG的运输、存储、加注等环节是在超低温环境中进行的,其对于相关材料的超低温性能提出了严格要求。超低温高锰钢基于其低温韧性、成本、制取工艺的优势逐渐超越传统低温材料成为研究热点,在此背景下,相关国际标准研制工作已逐渐展开。因此,本文重点分析了LNG船用钢材领域的标准现状,梳理了超低温高锰钢相关国际标准与渠道,结合船上LNG储罐高锰钢规范国际标准的内容分析,尝试给出了LNG船用钢国际标准的发展方向、主要挑战与机遇。
In the context of greenhouse gas emission reduction,the market scale of LNG as a marine fuel or maritime cargo is expanding,and the transportation,storage,and refueling of LNG are carried out in ultra-low-temperature environments,which puts forward stringent requirements on the ultra-low-temperature performance of related materials.Ultra-low temperature high manganese steel has become a research hotspot based on its advantages of low-temperature toughness,cost and manufacturing process,gradually surpassing the traditional low-temperature materials.Against this background,the development of relevant international standards has gradually begun.Therefore,this paper focuses on analyzing the current status of standards in the field of LNG shipboard steel,sorts out the relevant international standards and channels of ultra-low-temperature high manganese steel,and analyzes the content of international standards on high manganese steel for shipboard LNG tanks,to point out the direction as well as the main challenges and opportunities of the development of international standards on LNG shipboard steel.
