摘要
阐述了U型膨胀节内压失稳与爆破机理,介绍了其失稳与爆破时极限设计压力公式及来源,提出了防止U型膨胀节内压失稳与爆破的措施。
The paper discusses the mechanism of inner-pressure unbalance and demolition of U-type dilatation nodes,and introduces the formula and origin of pressure in the course of unbalance and demolition.The author puts forward the measures of how to avoid the case.
