Feb 09,2012 asme pipe definition data corrosion allowance#0183;Now,let's suppose that the vessel has a corrosion allowance of 1/8 or 0.125 inches.0.69 (uncorroded) + 0.125 (corrosion allowance) = 0.815 inches.The 3/4 inches plate is not suitable any more,and I must go to a 7/8,or 0.875 plate.What is a Corrosion Allowance? - Definition from Nov 11,2013 asme pipe definition data corrosion allowance#0183;Definition - What does Corrosion Allowance mean? Corrosion allowance describes an extra measurement added to the thickness of the wall.This helps estimate the expected metal loss throughout the lifespan of certain equipment.Since the depth of penetration may vary from case to case,corrosion allowance has a safety factor equivalent to 2.The Case for MACA The Optimization of CorrosionDec 01,2016 asme pipe definition data corrosion allowance#0183;The term Maximum Allowable Corrosion Allowance or MACA is used to describe this approach.This paper presents some arguments in favor of optimizing the corrosion allowance of pressure vessels,using a MACA based optimization for the design of new vessels rather than a pressure optimization or MAWP philosophy.
