style="text-indent:25px">蒸汽管道泄漏的現(xiàn)象和原因：蒸汽泄漏時，有大量的白色蒸汽冒出，伴隨有強烈的噪音，導(dǎo)致鍋爐房指示的蒸汽大量增加，壓力下降。管道破裂；閥門泄漏；墊片泄漏；管道焊接不符合規(guī)范要求；操作人員誤操作。蒸汽管道泄漏時的處理和要求：當(dāng)發(fā)現(xiàn)管道蒸汽泄漏的人員,要立即向當(dāng)班班長、段長、車間及調(diào)度匯報。分廠及車間有關(guān)人員立即到送現(xiàn)場,在保證人身安全的前提下,查找泄漏點,確定泄漏影響范圍,關(guān)閉相關(guān)閘門,必要時關(guān)停總閥泄漏處周圍要做如安全措施,防止蒸傷人。同時要密切監(jiān)視損壞部位的發(fā)展趨,,做好事故預(yù)想。</p><p style="text-indent:25px">蒸汽管道設(shè)計時應(yīng)該注意的要點：在選擇管徑時，要根據(jù)蒸汽的需求量。當(dāng)管徑太大的時候，就會增多投資，加大熱損失，同時也會增加冷凝水。當(dāng)管徑太小的時候，就會造成蒸汽使用點的壓力，蒸汽流量不足，較后使水錘和沖蝕的現(xiàn)象發(fā)生。因此在選擇管徑的時候，不能過大或者過小。在布置管道的時候，一定要符合應(yīng)力的要求，嚴格的進行應(yīng)力的計算。管道上π形補償器的設(shè)置、補償器固定點的推力以及與設(shè)備相連的蒸汽管道的配管等的設(shè)置都要滿足應(yīng)力的要求，這樣操可以使設(shè)計工作的效率得到提高。蒸汽管道設(shè)計時應(yīng)該要根據(jù)蒸汽的需求量設(shè)計。</p><div
