1 概况自从1956年在南京永利宁厂机械分厂试制成功中国第一台多层包扎式高压容器到1965年,我国自己建设的中小型化肥厂和各种化工厂、炼油厂所用的压力容器,除部分由前苏联和东欧一些国家引进外,其余全部是我国自己工厂制造的。当时我国的高压容器制造技术水平与世界先进国家的差距不算大,如1965年,我国制造设计压力为32MPa的氨合成塔外壳直径已到φ1000mm,已采用了16Mn、15MnV等低合金高强度钢。可是十年“文化大革命”的空前浩劫,使我国的压力容器制造水平一下子
1 Overview Since 1956, Nanjing Yongli Ning Machinery Plant trial successfully produced China’s first multi-layer bandaged pressure vessel to 1965, China’s own construction of small and medium fertilizer plant and a variety of chemical plants, refineries used in pressure vessels, Except for some imported from some countries in the former Soviet Union and Eastern Europe, the rest were all manufactured in our own factories. At that time, the gap between China’s high-pressure vessel manufacturing technology and the advanced countries in the world was not large. For example, in 1965, the diameter of the ammonia synthesis tower with the design pressure of 32 MPa in China has reached φ1000 mm. Low-alloy high-strength steels such as 16Mn and 15MnV have been used . However, a decade of “Cultural Revolution” unprecedented havoc, so that China’s pressure vessel manufacturing level suddenly
