Standard specification for steel castings , general requirements , for pressure - containing parts 承压部件用钢铸件一般要求的标准规范
Standard specification for steel investment castings general requirements , for pressure - containing parts 承压部件的钢熔模铸件一般要求的标准规范
The main reason of the life loss of steam drum , which is located outside the boiler , is the low cycle fatigue 炉外承压部件中的汽包,其寿命损耗的主要方式是低周疲劳。
Standard specification for steel castings , martensitic stainless and alloy , for pressure - containing parts , suitable for high - temperature service 高温设备承压部件用合金钢和马氏体不锈钢铸件标准规范
The pressure component inside the boiler , represented by superheater , whose main reason of life loss is long - term creep 对于以高温过热器为代表的炉内承压部件,其寿命损耗的主要方式主要是长期蠕变。
And then a software system was developed under visual c - r environment for evaluation the fatigue life of boiler drum 最后本文用visualc + +开发一套适用于锅炉承压部件(汽包为代表)的疲劳寿命评估分析系统。
Standard specification for castings , iron - nickel - chromium and nickel alloys , specially controlled for pressure retaining parts for corrosive service 防腐设备承压部件用特殊控制的铁镍铬及镍合金铸件的标准规范
Fatigue failure in the power plant boiler drum and pressure piping is the common failure , which caused by fatigue loading and others 锅炉承压部件(汽包等)及压力管道在交变载荷和其它因素作用下发生疲劳破坏是一种常见的失效方式。
In the light of the fact that elastic creep damage happens to heat resistant steel used as pressure elements like steam pipeline and steam pockets in heat - engine plants at high temperature and under high pressure , this article gives a complete constitutive description of the damage , building up the theory of phenomenology about creep damage 摘要针对火电厂中蒸汽管道与汽包类承压部件用的耐热钢,在承受高温高压时发生弹性蠕变损伤问题,给出完整的损伤本构描述,建立起唯象学蠕变损伤理论。
In this paper , the strength theory is adopted to analyze the stress of the pressure component of boiler , and the calculation method of metal fatigue and creep is adopted to estimate the life loss of the boiler . meanwhile , the short - cut calculation method is put forward which can meet the requirement of on - line monitoring . on the basis of above , the on - line monitoring and management system of boiler life is developed 本文采用强度理论和疲劳、蠕变寿命计算方法,分别对电站锅炉的炉外、炉内主要承压部件进行了应力分析和寿命计算,并提出满足在线监测要求的简化计算方法,在此基础上,开发了锅炉承压部件的寿命在线监测和管理系统。
