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. |

非金属-帆布膨胀接头耐压创新高纪录,至 -1kg/cm² (370°C) |
|
2006年12月底, 於国内中部之火力发电厂, 连接过热(370°C) 蒸汽管之金属接头破裂, 导致管内之压力无法维持於 -1kg/cm². 修复补焊或更新此金属接头之工程十分艰巨, 且必须停机方可进行. 对电厂而言其损失将非常高. 本公司有幸参与并建议以本公司设计最经济之覆合式帆布接头为替代方案. 全案自设计, 制作至安装完成仅7天 (期间该部机组仍继续运转). 目前该管内压力已可降至并维持於-1kg/cm², 机组亦回复正常运转. 值得一提者为案内接头所承受 -1kg/cm² 之压力 远超出国内外所有膨胀接头制造厂商产品耐压上限(约0.3kg/cm²), 更何况其操作温度高达370°C. |
