Hello,
I need help. I am working in a proyect design of a pressure vessel and I need to select the appropriate material.The vessel will be filled with Ethyl Mercaptan which is corrosive, and a customer requirement is that the vessel material must be carbon steel. I am aware that in the calculation I must introduce a corrosion factor.
My question is the following; Could the Ethyl Mercaptan modify the molecular structure of the carbon steel, turning it into a weaker material?
The carbon steel available is: ASTM A-516 Grade 70
Its chemical composition is: C: 0.31; Mn: 0.85 - 1.20; P: 0.035; S: 0.035; Si: 0.15 - 0.40; Cb: 0.020
Yield strength: 38Ksi Mínimun
Tensile strength: 70-90 KSI min
The filling substance is: CH3CH2SH – (Ethyl mercaptan)
Thanks very much
