壓力容器返修焊縫，同一部位返修超過2次合格嗎？

制造過程中的焊接返修是不可能完全避免的。為了保證焊接返修的質(zhì)量，有下面幾方面要求。

不銹鋼反應(yīng)釜不能運行的原因

不銹鋼反應(yīng)釜的閘閥打開不當(dāng)，或者閥門的開閉順序不對，造成裝置的工作壓力過高或蒸汽倒流。冷凝水沒有及時排出或?qū)嶋H操作有問題，從而導(dǎo)致設(shè)備在實際操作中能夠經(jīng)受住壓力。因為在實際工作中，制冷壓縮機會被抽吸，所以氣體會進入裝置，制造出爆炸性的混合物。過早地關(guān)掉水泵將造成設(shè)備局部過熱熔化和破裂。把不適當(dāng)?shù)脑贤度氲讲缓线m的原料中，造成在購買過程中產(chǎn)生的熱裂紋和爆裂。

化工設(shè)備管理方法分析

隨著化工企業(yè)規(guī)模的逐步擴大，化工設(shè)備的管理內(nèi)容也日趨復(fù)雜。能否呆用科學(xué)的方法對化工設(shè)備進行管理是當(dāng)前化工企業(yè)的重要研究課題。

化工設(shè)備的防腐蝕措施

現(xiàn)在隨著工業(yè)的發(fā)展，尤其是在一些工業(yè)園區(qū)，化工公司不在少數(shù)，化工設(shè)備的使用更是不在少數(shù)。化工設(shè)備作為生產(chǎn)中的主流設(shè)備，對化工設(shè)備的防腐蝕保護。因為一旦化工設(shè)備遭到腐蝕，會的縮短設(shè)備的使用壽命，增切企業(yè)的生產(chǎn)成本，嚴(yán)重的還會引發(fā)重大的生產(chǎn)事故，為企業(yè)帶來損失。今天小編就為大家介紹一下，化工設(shè)備該如何進行防腐。

化工設(shè)備在生產(chǎn)中的作用詳解

包括化工設(shè)備在內(nèi)的所有化工機械都是化學(xué)工廠中實現(xiàn)化工生產(chǎn)所采用的工具。化工產(chǎn)品生產(chǎn)過程的正常運轉(zhuǎn)，產(chǎn)品質(zhì)量和產(chǎn)量的控制和保證，離不開各種化工設(shè)備的適應(yīng)和正常運轉(zhuǎn)。化工設(shè)備的選配需通過對整個化工生產(chǎn)過程的詳細計算、設(shè)計、加工、制造和選配，要適應(yīng)化工生產(chǎn)所需要。
