FABRIC EXPANSION JOINT FOR SERVICE
PRESSURE TO -1KG/CM², 370°C |
|
Late Dec./2006, in a local fossil power plant in Taiwan, cracks developed on a metal expansion joint, which was used to stop ambient air from being sucked into the over-heated steam pipe (-1kg/cm², 370°C). To repair or to replace the failed metal joint will be very difficult and can only be done with the system being shut down. Alternative to solve the problem became immeniant. We were called on and came up with a very cost effective new designed composite fabric expansion. We spent less than 7 days to get the job done (from order to installation) whilst the system remained in operation. Since then, the pressure in the duct came down again to and maintained at -1kg/cm². The power plant people were happy with the results. |

非金屬-帆布膨脹接頭耐壓創新高紀錄,至 -1kg/cm² (370°C) |
| 2006年12月底, 於國內中部之火力發電廠, 連接過熱(370°C) 蒸汽管之金屬接頭破裂, 導致管內之壓力無法維持於 -1kg/cm². 修復補焊或更新此金屬接頭之工程十分艱鉅, 且必須停機方可進行. 對電廠而言其損失將非常高. 本公司有幸參與並建議以本公司設計最經濟之覆合式帆布接頭為替代方案. 全案自設計, 製作至安裝完成僅7天 (期間該部機組仍繼續運轉). 目前該管內壓力已可降至並維持於-1kg/cm2, 機組亦回復正常運轉. 值得一提者為案內接頭所承受 -1kg/cm² 之壓力 遠超出國內外所有膨脹接頭製造廠商產品耐壓上限(約0.3kg/cm²), 更何況其操作溫度高達370°C. |
