Question: This question relates to rubber linings on ISO tanks. “Do you have any idea what a rubber lined IMO 1 would have cost before 2000 ex USA? Carbon steel, 4 bar MAWP, 20,000 liter, manufactured in 1992 by Zenith Engineering in Singapore.”
Tank Guru: The best estimate that I can give you is somewhere between $35,000 – $50,000 USD. It would depend on a number of factors, including the number and type of valves (lined?), the thickness and grade of rubber used in lining the tank interior, whether the tank also carried IM-101 (3/8″ wall thickness for AAR-600) approval, etc. But it would have definitely been more expensive that a standard stainless steel IMO 1. Hope this helps.
