凝汽器钛管化学清洗的研究与应用
摘要
某电厂凝汽器钛管存在严重的结垢现象。对此
通过静态小型试验筛选出TPRI-5清洗配方
并进行了其对钛管吸氢腐蚀影响的试验。结果表明
TPRI-5清洗配方能有效去除凝汽器钛管的钙质硬垢
除垢率达95%以上
对钛管的腐蚀速率低
平均腐蚀速率为0.003(g/m2)/h
且不产生吸氢腐蚀
清洗前后钛管氢含量无变化。
Abstract
To clear the severe calcium scale on the Ti pipes of the condenser in a power plant
TPRI-5 cleaning formulation was selected through a lot of tests
and experiment about the impact of the cleaning formulation on the hydrogen embrittlement of Ti pipe was conducted.Results show that
TPRI-5 cleaning formulation can efficiently clear the calcium scale
and the scale removal rate is higher than 95%;moreover
the formulation has a 0.003 g/(m2h) corrosion rate on Ti pipe
which is very low
and during the clearning no hydrogen embrittlement occurs.Therefore
TPRI-5 cleaning formulation is suitable for Ti pipes chemical clearing.
