BASIC HEAT TRANSFER AND SOME APPLICATIONS IN

Volume 2,Pages 21-33,SPE 2002) John Vlachopoulos and David Strutt polydynamics Heat transfer is a branch of engineering science which seeks to determine the rate of energy transfer between bodies as a result of temperature differences.The concept of rate is the basic difference between heat transfer and thermodynamics.Cathodic Protection for Above Ground Storage Tanks Tank designers use coatings as a primary defense against corrosion on the internal wetted surfaces of water storage tanks.Coating systems,however,are less than perfect and they degrade over time.Corrosion is a pervasive phenomenon and wherever there are voids,holidays or coating failures--the galvanic corrosion cell will rush into action Caustic Soda Tank and Storage GuidelinesThe weight of 50% caustic soda solution is 1.5 times that of an equal volume of water.General Storage Guidelines for 50% Caustic Soda Solution Product should be stored between 85° to 100°F (29° to 38°C).Over time,precipitation of calcium and magnesium hydroxide,carbonates and oxalates will occur.A 2-4 year out-of-service tank cleaning
