Corrosion and material selection issues in the sulfur removal pipeline of sulfur recovery fluids!
Thread Content
Steam ejectors are used for the degassing of liquid sulfur in the sulfur recovery liquid sulfur tank, to extract the S and H2S gases contained therein and send them to the incinerator. The medium transported through this section of exhaust pipeline contains water vapor, S mist, and H2S; is ordinary carbon steel (with corrosion allowance considered) sufficient for this purpose? I would like to ask the experts in operation: regarding the corrosion that occurs during the operation of this pipeline, is it necessary to replace it with stainless steel? ? ?
Over time, 304 stainless steel can also become completely corroded. Is 316L better?
Carbon steel should work, but a jacket is required
A carbon steel fully jacketed pipeline will do, no problem :)
What is the temperature? If carbon steel pipes are in areas with low temperatures, along with liquid water and acidic substances, corrosion will be severe, right?
