一、前言 凝汽器铜管遭受腐蚀,给电厂的安全经济运行带来很大危害。我厂曾因铜管的严重腐蚀,经二年时间运行后二台五万机组的凝汽器铜管就被迫全部调换更新,换管70吨,仅铜管材料费就达180万元。此外,由于凝汽器泄漏,污染锅炉给水,严重威胁高温高压锅炉的安全运行。因此,滨海电厂选用新的耐腐蚀管材是迫切任务。为了开发我国凝汽器的新耐腐蚀管材,水电部和冶金部于1978
I. Introduction Condenser copper pipes are subject to corrosion, which brings great harm to the safe and economical operation of power plants. Because of the serious corrosion of copper pipes in our factory, after two years of operation, two sets of condenser copper pipes of 50,000 units were forced to be replaced and replaced for 70 tons, and the cost of copper pipe materials alone reached 1.8 million yuan. In addition, due to the condenser leakage, pollution boiler feed water, a serious threat to the safe operation of high temperature and pressure boiler. Therefore, the selection of new coastal power plant corrosion-resistant pipe is an urgent task. In order to develop a new corrosion-resistant pipe condenser in China, Ministry of Water Resources and Metallurgy in 1978
