台灣地處亞熱帶,高溫潮濕及鹽分均偏高之海島型腐蝕環境,加上近來工業污染日益嚴重,對鋼鐵的腐蝕是個普遍而且嚴重的問題。本研究的主要目的是提高石化環境下結構與設備之防蝕性能,為了瞭解腐蝕劣化型態及原因,遂分別進行可靠度壽命試驗、取樣試片檢驗、目視檢查、成分分析、Deposit與水質分析,結合以維護策略之矯正維護所強調應用非破壞檢測與腐蝕診斷之精密檢測兩種方法,作為缺陷分析及把握腐蝕狀況之變遷,提供設備腐蝕劣化傾向的參考資料。非破壞檢測技術採用PT、MT及磁漏檢測和厚度測量等方式,進行設備缺陷或裂縫之檢測;腐蝕診斷檢測主要以目視檢查及腐蝕生成物或沉積物取樣作高層次診斷分析為主,來進行設備腐蝕現況及腐蝕之判斷。本文針對目前常見的鋼鐵材塗裝系統,包括環氧樹脂聚胺面漆、氟素樹脂面漆、聚胺基甲酸酯樹脂面漆、環氧酚醛樹脂面漆及奈米陶瓷漆等塗裝系統進行大氣曝露試驗,希望藉由實地腐蝕試驗,累積更多腐蝕數據及經驗。經九個月的大氣曝曬結果,證實環氧樹脂聚胺面漆塗裝系統具有優異的防蝕性能,適合於嚴苛腐蝕環境下之鋼鐵設備使用。因此,透過正確的設備腐蝕檢測與評估,才能達成有效之石化設備維護管理,降低現場設備腐蝕風險。主要結論如下:經過文獻蒐集及一系列之實驗與診斷檢測運用,建立了石化廠設備腐蝕維護檢測之標準,包括完成了石化設備腐蝕檢測技術及檢測標準、石化設備腐蝕分類、維護策略建置等技術。且已經順利在公司及集團公司內的腐蝕維護檢測中使用,情行相當良好。
Located in the subtropical zone, Taiwan is an island of high temperature, humidity and high salinity, namely a corrosive environment. In addition, industrial pollution has been increasingly severe recently. Thus, steel corrosion is now a widespread and serious problem. This study aims to enhance anti-corrosion properties of the structure and the equipment in a petrochemical environment. In order to understand the types and reasons of corrosion and degradation, this study conducted reliability life testing, sampling coupon testing, visual inspection, component analysis, and analysis of deposits and water. In addition, two precision measurement technologies, nondestructive testing and corrosion surveillance, were employed based on the idea of corrosive maintenance of maintenance strategies to conduct defect analysis and have a grasp of changes in corrosion, in order to offer reference for the tendency of equipment corrosion and degradation. The nondestructive testing included PT, MT, magnetic flux leakage testing, and thickness measurement to see whether there is any defect or chink on the equipment, while the corrosion surveillance included visual inspection and high-level analysis of samples of corrosion products or deposits, in order to understand the status quo of equipment corrosion and make judgments on corrosion. In this study, some coating systems for iron and steel in common use, such as epoxy resin polyurethane coating, fluoropolymer resin coating, polyurethane coating, epoxy novolac resin coating and nano ceramic coating were tested with the atmospheric exposure test. It is hoped to obtain more corrosion data and experience by means of such an on-site corrosion testing. After exposure to the atmosphere for nine months, epoxy resin polyurethane coating was found to have excellent anti-corrosion performances, and therefore is suitable for the iron and steel equipment in a severely corrosive environment. As a result, only through adequate testing and evaluation of equipment corrosion can we fulfill effective maintenance management of the petrochemical equipment, and at the same time minimize the risk of the equipment being corrosive. The conclusion is as follows. After literature search and a series of experiments and diagnostic tests, the standards of corrosion maintenance testing for the equipment of petrochemical plants are therefore established, including testing techniques and standards for petrochemical equipment, corrosion category, maintenance strategies, etc. The above standards have been successfully applied to the corrosion maintenance testing by the Company and the Group with positive outcomes.
