摘要
新国家标准GB/T9222-2008《水管锅炉受压元件强度计算》中采用的弯管强度计算新方法及其主要公式的由来。通过与老标准的对比分析,指出新标准弯管强度计算方法在老标准基础上有重大改进。
The strength calculation new method and main formula of bend tube in new national standard GB/T9222 -2008 are introduced herein. After the contrast and analysis between the new and old national standard, the strength calculation method of bend tube in new standard has made great advances based on the old standard are indicated.
