Earlier on I mentioned these large ammonia tanks that no longer meet the pressure requirments, decided to bring one home to make a vault for my veggie oil. With a 1/2" shell 3/8" caps i should keep the bears outa my grease.



With 1/2" shell 3/8" end caps this tank is heavy, my guestimate is they weigh 6500 maybe 7,000 lbs.
