The purpose of rubber lining is to protect the vessels, tanks and piping against corrosion and/or erosion damage and increasing the life of their service. In present work isoprene/natural rubber is used to prepare the lining material for 33% diluted Hcl acid storage tank. The required parameters for rubber lining material are minimum tensile strength of 110 kgf/cm2, minimum elongation at break 350%, maximum ash content 35% and maximum acid absorbed 12%. To achieve the above said results a rubber lining material with appropriate composition is prepared in the form of sheet with desired thicknes...

To achieve the above said results a rubber lining material with appropriate composition is prepared in the form of sheet with desired thickness and the sheets are cut in to the specimens as per ASTM/IS Standards and tests like tensile strength, Ash content test and Acid bleed tests were performed and the results obtained are tensile strength=112.80 kgf/cm2, Elongation at break are 438.92%, ash content=31.85% and acid absorbed =7.85%.
