Dear all,
I was trying to find a reason why almost all corrosion circuit guidelines (of different companies) always use the 50 psi change in pressure and 25 F change in temperature to break the corrosion circuit and start a new one. While I understand (I think!) why they break the circuits at 25 F temperature change, I cannot find a reason behind the 50 psi (approx. 4 bar) rule!
Can somebody shed light on this?
By the way, for the 25 F (approx. 13 C) rule - I think this is because the corrosion rate of CS doubles every 10 C increase in temperature (a rule of thumb used in corrosion).
Regards,
Abdulaziz
