浙江至德鋼業有限公司是專業生產不銹(xiu)鋼管(guan)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)于其脆性轉變溫(wen)(wen)(wen)(wen)度(du)(du)時(shi)，其沖擊(ji)韌性急(ji)劇下(xia)降，造成脆性斷裂。操作溫(wen)(wen)(wen)(wen)度(du)(du)等于或低(di)(di)于-20℃時(shi)，按(an)規范要求(qiu)選用(yong)低(di)(di)溫(wen)(wen)(wen)(wen)材(cai)(cai)料(liao)是無(wu)疑的。由于地區環境溫(wen)(wen)(wen)(wen)度(du)(du)的影響，或如液化氣體急(ji)劇汽化，管道金(jin)屬溫(wen)(wen)(wen)(wen)度(du)(du)可能等于或低(di)(di)于-20℃時(shi)，亦應按(an)相當低(di)(di)溫(wen)(wen)(wen)(wen)材(cai)(cai)料(liao)選用(yong)，并要求(qiu)按(an)設計最低(di)(di)溫(wen)(wen)(wen)(wen)度(du)(du)做沖擊(ji)試驗。
