Corrosion Under Insulation (CUI) in pipingc systems consumes a significant percent of the maintenance budget in the petrochemical industry. Prevention of CUI by the use of (1) thermal spray aluminum, (2) stainless steel pipe, (3) expanded metal cages for personnel protection instead of insulation and (4) aluminum foil wrapping are discussed in terms of long term protection, installed cost and Life cycle cost.
Performance of formulations of antifouling coatings to protect carbon steel from effects of microbiologically influenced corrosion (MIC) and marine biofouling in a tropical harbor seawater was assessed by field and laboratory experiments. • Scanning electron microscopy (SEM). • Energy dispersive spectroscopy (EDS). • X-ray diffraction (XRD). • Seawater immersion.
