Q1: Cov qauv tsis muaj tseeb tshaj plaws hauv almoy hlau kav?
A1:Phab ntsa thinning los ntawm yaig-corrosion ua rau muaj kev kub ntxhov ntau dua li Welds or}} Cov kev ntxhov siab ntawm kev ntxhov siab hauv cov kev pabcuam hauv qab no {8} rupture ua qhov tseem ceeb hauv kev siv kub hnyav tshaj qhov kev txwv tsim kho mob tawg lossis dej-submerged .
Q2: Yuav ua li cas thiaj li yog Metallurgical kev soj ntsuam txiav txim tsis tau ua rau?
A2:Fractographe qhia seb puas tau pib ua haujlwm los ntawm kev ntsuas hluav taws xob tsis zoo rau kev kho mob los sis cov khoom siv hluav taws xob tsis raug cai muab cov ntawv me me muab cov ntawv qhia dav dav Kev Tshaj Tawm Kev . Cov txheej txheem no ua ke los tsim lub hauv paus ua rau tsis ua {}}
Q3: Cov kev coj ua zoo tshaj plaws rau kev tiv thaiv kev yaig-corrosion hauv cov kav dej?
A3:Maintaining flow velocities below erosion-corrosion thresholds (typically 3-6 m/s for water). Using erosion-resistant alloys like 6% Mo super austenitics in severe services. Installing flow straighteners to eliminate impingement at bends. Applying hard-facing or ceramic linings in high-wear chaw .} thickness tsom qhia cov teeb meem teeb meem ua ntej tsis ua tiav.
Q4: Yuav ua li cas thiaj li muaj kev ntxhov siab corrosion cracking yuav mitigated hauv alloy kav?
A4:Selecting resistant materials like duplex stainless steels for chloride environments. Applying stress-relief heat treatment after welding and forming. Controlling operating temperatures below cracking thresholds. Using inhibitors to modify the corrosive environment. Avoiding stagnant conditions that concentrate corrosive Hom .} Tus qauv tsim nyog me me kev nyuaj siab thiab kev ntxhov siab ntau.
Q5: Cov tswv yim zoo dab tsi nthuav tag nrho cov yeeb nkab hluav taws xob lub neej?
A5:Implementing risk-based inspection programs focusing on critical areas. Establishing corrosion monitoring programs with multiple techniques. Training personnel to recognize early warning signs of degradation. Maintaining proper chemical treatment programs for internal protection. Keeping complete material and service history records for lifecycle analysis. Developing proactive replacement plans based on remaining Kev ntsuam xyuas lub neej .
