浙江至德鋼業有限公司是專業生產不(bu)銹鋼(gang)管工廠，企業技術人員根據多年的不銹鋼管生產經驗，總價認為管道在運行過程中，常見堵、漏、腐等問題，失效形式總結如下。

 材(cai)(cai)料(liao)溫(wen)(wen)(wen)(wen)度(du)(du)低(di)(di)于(yu)其(qi)脆(cui)性(xing)轉(zhuan)變溫(wen)(wen)(wen)(wen)度(du)(du)時(shi)，其(qi)沖擊韌性(xing)急劇(ju)下(xia)降，造成脆(cui)性(xing)斷(duan)裂。操作(zuo)溫(wen)(wen)(wen)(wen)度(du)(du)等于(yu)或(huo)低(di)(di)于(yu)-20℃時(shi)，按(an)規(gui)范要求選用(yong)(yong)低(di)(di)溫(wen)(wen)(wen)(wen)材(cai)(cai)料(liao)是無疑的。由于(yu)地區環境溫(wen)(wen)(wen)(wen)度(du)(du)的影(ying)響(xiang)，或(huo)如液化氣體急劇(ju)汽化，管道金屬溫(wen)(wen)(wen)(wen)度(du)(du)可能等于(yu)或(huo)低(di)(di)于(yu)-20℃時(shi)，亦應按(an)相當(dang)低(di)(di)溫(wen)(wen)(wen)(wen)材(cai)(cai)料(liao)選用(yong)(yong)，并要求按(an)設計最低(di)(di)溫(wen)(wen)(wen)(wen)度(du)(du)做沖擊試(shi)驗。
