A customer gave our shop an older PST steel cylinder, working pressure 3000 psi. It is approximately 7” in diameter, and appears to be a little shorter than a HP 100.
I have not seen one of these cylinders before, and cannot find any information on it (e.g. capacity at working pressure, years of production, etc). However, I did find that a SB user sold one of these through the SB Classifieds, about 4 years ago. That user posted a picture of his cylinder. Our cylinder looks the same, with the exception of a later (higher) serial number, and a later ‘birth’ date (original hydro date), 1984 in our case. 3000 psi PST steel tanks 94cf? Galvanized and very nice.
If anyone knows anything about this particular line of PST cylinders, I would love to hear from you. I am going to determine the internal volume of the cylinder, and try to back calculate to capacity, at 3000 psi. I will dive it, to get a feel for its buoyancy characteristics. But, I would love to know more, if there is information out there.
