THE ANALYSIS OF RATE CORROSION ON THE TUBE UNIT WATER TREATMENT PLANT

Abstract

All of The Company use the tube to move liquid from one place to another place. There are many problems that occur on the tube, one of them is the corrosion. Corrosion is a material damage especially the metal contacts in general as a result of the reaction with the environment. The purpose of this analysis is to observe and understand what types of corrosion and analyze the rate of corrosion on the tube. The type of water that passed on the tube is water service, type of the type of corrosion located on the tube is errosion corrosion, stress corosion cracking, dew point corrosion. From the analysis results using test methods reduced weight with media coupon taken during the period of the observations show that the rate of corrosion on a range of pH 6,51 until 6,88 is 16,64807 µm.years .   

Key Word: Type Of Corrosion, Corrosion and Corrosion Rate, Tube.
