对主蒸汽管断裂原因进行了分析。
炼油厂许多主蒸汽管线，直经和质量较大，管线在管架上常被拉裂。
Many main vapor pipes in oil refineries have long diameter and big weight, so the pipes often crack on the common supporters. A new sliding supporter is designed to solve the problem.
热力钢弯管是主蒸汽管道的薄弱部位之一，其寿命直接关系到整个管道系统寿命。
The heat - resisting steel elbow is one of the weak parts of the main vapour piping, the life of which is directly related to the life of entire piping system.
本课题选取适合寿命评估的高温高压部件，如主蒸汽管道及过热器管进行寿命管理研究。
In this paper, high temperature and high-pressure components fitting for life assessment such as main steam pipeline and boiler tube were selected for life management studying.
结果表明，断裂是由腐蚀疲劳引起的，阀体材质不舍格和焊接结构不合理是主蒸汽管失效的主要原因。
The results shown that the rupture is caused by corrosion fatigue. The main reasons of failure of main vapour tube are unqualified valve material and unreasonable welded construction.
实现产出和消耗蒸汽的连续平衡。主压力控制方法控制着输入锅炉的总热量以及流入每个锅炉联管箱的蒸汽量。
Achieve continuous balance between produced and consumed steam. This master pressure control approach controls total heat input into boilers, as well as total steam flow into each header.
