Regarding the selection of materials
Thread Content
For media containing hydrogen sulfide, which material should we choose? For media containing carbon dioxide, which material should we choose? For media containing chloride ions, which material should we choose? And when two or three of the aforementioned substances are present together, how should we select a material? Additionally, I would like to know at what concentration of these media should their presence be taken into consideration when choosing a material Which standard specifies it? Please help recommend some. Thank you very much
For media containing hydrogen sulfide, we choose chromomolybdenum steel； For media containing carbon dioxide, carbon steel should be sufficient; a corrosion margin of 3 mm can be considered. For media containing chloride ions, we should choose chromomolybdenum steel ； When two or three of the above are combined, which chromium-molybdenum steel should be chosen? ； What do you think? :
Thank you for your reply. I’m new to this industry; I’m a complete beginner, haha
