GB6654-1996《压力容器用钢板》标准的技术水平虽较原标准GB6654-86有了一定的提高,但相对压力容器的使用要求及国外先进水平标准而言,仍存在着一定的差距。全国压力容器标准化技术委员会一直在努力促进压力容器用钢板标准水平的提高,先后与武汉钢铁公司、舞阳钢铁公司、重庆钢铁公司等单位协商,促进这些钢板生产厂制订了技术水平高于GB6654-1996标准的企业标准,从而为修订该国家标准奠定了基础。 20世纪90年代初期,根据我国压力容器向大型化发展的需要,中国通用机械工程总公司与武汉 GB6654-1996 “pressure vessel steel” standard technical level although the original standard GB6654-86 has been a certain increase, but the relative pressure vessel requirements and foreign advanced level standards, there are still some gaps. National Pressure Vessel Standardization Technical Committee has been working hard to promote the standard level of pressure vessel to improve the steel plate, one after another with the Wuhan Iron and Steel Company, Wuyang Iron and Steel Company, Chongqing Iron and Steel Company and other units to negotiate and promote the development of these steel plate production technology level higher than GB6654-1996 Standard corporate standards, which laid the foundation for the revision of the national standards. In the early 1990s, according to the needs of large-scale development of pressure vessels in China, China General Mechanical Engineering Corporation and Wuhan
