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.
