预防锅炉受热面管材带裂纹流转的措施

Discussion on Flow of Cracked Tube Materials for Boiler Heat Surfaces

为了减少因原材料本身缺陷而影响火力发电厂锅炉机组水压试验或168h试运行,以及锅炉日常运行而造成的财产损失及人身安全,通过四个原材料裂纹案例分析,从人的因素、检测设备的因素、规章制度的因素、环境因素四个方面分析了出现管材带裂纹流转至锅炉制造企业的原因,并给锅炉制造企业及监理单位提出了预防建议。

To reduce the influence of drawbacks of raw material itself on hydrostatic test or 168 h commissioning of boiler unit in thermal power plants, or on property loss and human security during daily operation of boiler, the reason why tube materials with cracks flow to boiler manufacturer is analyzed from four aspects, namely factors of personnel, testing equipment, rules, and the environment, based on 4 actual cases. Suggestions on prevention of similar problems are finally proposed to boiler manufacturers and supervision units.
