This is very riveting knowledge, pun intended. I had no idea they used rivets in the early days with low strength steel. No wonder they had the problems they did. Trying to contain 160psi with only rivets? That would be something I wouldn't want to be anywhere close to when something weakened to the point of failure.volvolugnut wrote: ↑15 Mar 2022, 13:12 Early steam engines and industrial boilers were prone to failure. These explosions prompted the American Society of Mechanical Engineers (ASME) to create rules for design and operation of pressure vessels and boilers. Related organizations of inspectors and insurers also improved safety by improving education of operators and owners. It is remarkable that these earlier locomotives, pressure vessels, and boilers were all riveted low strength steel. High strength, high temperature steel and welded construction were developed much later.
Much of my working years were designing large pressure vessels at relatively low pressure ( 8 to 13 foot diameter and 40 to 80 PSI).
The locomotive pictured operated at 160 PSI.
Tomorrow will be a photo (taken by others) of one of the largest steam locomotives every built. Stay tuned!
I appreciate your interest in my ramblings.

Riveted steel joints are OK, IF properly designed and installed. Poorly welded joints can fail also, so they are often X-rayed to prove the joint is good. Whatever you do in a critical device the materials, process, assembly, and testing must be all good and trusted. The early failures were often because someone did not know enough to do the right things.

The Union Pacific Railroad restored the 4014 steam locomotive several years ago. This is a 4-8-8-4 design which means it has 4 pilot wheels in the front, 8 drive wheels, a pivot point in the center, another 8 drive wheels, and 4 undriven wheels at the rear. Fuel oil is carried in the multiple axle car behind the locomotive. Th locomotive has toured many south central states in the last couple years. I have not seen it, but have seen a sister 4-8-8-4 in Denver at the Forney Museum of Transportation many years ago. This locomotive weighs over 1 million pounds.
Bonus: Very looong video following the locomotive on a road trip.

If this does not give you chills, you do not like steam trains.

It would have been designed with slide rules and it still had rivets. Pressure rating on this engine was 300 PSI.
If you want more information, see Wiki https://en.wikipedia.org/wiki/Union_Pacific_Big_Boy
My early engineering classes about 1976 still had a few problems on riveted joint design for pressure.

Very interesting read, thanks for sharing. Apparently there is big boy 4012 on display at Steamtown Historical Site in Scranton PA. That's only 2 hours from where I live. It would be a lot of fun visiting that museum, they have a lot of other interesting locomotives as well.

Technically it wasn't an original idea. I found a similar thread last posted in 10 years ago, and rather than digging it back up I started a new one. Jblackburn started the original thread found here .volvolugnut wrote: ↑17 Mar 2022, 08:27 gnalan,
