Abstract: Wall thickness monitoring is very critical of the process pipes and transporting storage vessels in the power and the petrochemical industries. This is to assess their corrosion and erosion rate since failure of such equipment is very catastrophic. In this study, the wall thickness of liquefied petroleum gas (LPG) storage vessels were measured by means of ultrasonic thickness gauge and the operating pressure (OP) of each vessel evaluated. The purpose is for routine monitoring and safety assessment to ascertain the integrity of storage and transporting vessels. The OP of each vessel was compared with the vapor pressure of tropical LPG and the integrity of each vessel inferred. The minimum and the maximum margins are 0.4 bar (0.04 MPa) and 5.6 bar (0.56 MPa) respectively. The safety implications of the results are also discussed for each vessel tested. The result shows that all the vessels are safe and fit for use.
