Experts, We are facing a situation where the LPR readings is showing Corrosion of around 13 MPY, Coupons (45days) retrieval is showing 17 MPY, in Cooling water System with Several HE and equipments
The whole system along with the HX are complete Carbon Steel built, under such readings there should have been heavy corrosion that could be seen in the water conditions, but the Return Water shows iron Fe2 Less then 0.4ppm consistently for more then past 3 months. Has anyone faced such experience? In what circumstances the Readings could be misleading?
