Dismantling a Gas Tank

That gas tank has evidently reached the end of its life:

Many of the nearby gas pipelines end in open stubs and a concrete crusher worked over one of the pads for a long-vanished cylindrical tank, so it looks like they’re scrapping the whole installation. I think the project to install an elevator for the Walkway lands nearby, which may explain everything.

I took the picture from the Walkway, aligning the SX230HS lens through the chain-link fence. Occasionally a small lens wins over more glass!

  1. Imagine the poor guy who wielded the gun on the inside of that tank when he flattened the ends of those cagillion rivets. I’m guessing they slid the hot rivets and bucked them up from the outside, hence the riveter being on the inside. I bet he was lucky if he had balls of cotton in his ears.

    1. bucked them up from the outside

      It’s impossible to tell, even from the original pictures, which way those rivets went. Based on the best image, the outside ends seem to be conical, which would suggest they were bucked from the inside, but …

      If that tank still stands the next time I ride by, I’ll get a closer look.

      They used to say “deaf as a boilermaker” for well and good reason!

  2. I figured the rivets would be installed from the outside because it would be an easier throw from the rivet oven on the outside than trying to get it through a hole in the vessel to someone on the inside. I guess they probably pre-riveted as many as they could before they erected each segment, but there still had to be quite a few that had to be installed in the field. An old timer once told me that an inspector would come around with a chipping hammer and give each rivet a whack to see if it was properly installed. A dull sound would indicate a loose rivet which had to be cut out with a torch and reinstalled. He said when the inspector wasn’t around they would reheat the rivet in place with a torch, put a piece of cellophane from a pack of cigarettes on the hot rivet and give it another shot with the rivet gun. This would take the dent out of the rivet that the inspector put in it with the chipping hammer so it looked like a new rivet when the inspector came back to recheck it.

      We have a big line-drawing book (Superpower by Weitzman) describing how they built the classic steam locomotives at the Lima works. The hammer driver is inside, the bucker is outside, and the rivets have round heads on both ends… after appearing as a white-hot star in the hole!
