We built highway safety products and machines and were certified through the state of California for doing work for CalTrans. All of our welds and equ...

I just sent Chris a few photos to post for me. The boiler drawing for the CP173 is from RRSC and is for a copper boiler using. We used 5.500" DOM with .250" wall and has an OD of 6.00" and has been honed for use in hydraulic cylinders. The real larger section is 7.500" OD with .312" wall. I have the...

The girders on the top of the crown sheet are .375" x .750" x 7.00". The amount of pressure to bend the girders, distort the crown sheet and bend the stays is much more than what is generated. The second reason why we went went this design is that the throttle body lies right in the center of the cr...

The shear forces again are much greater than the operating boiler pressure and even the pressure the boiler can produce. Gene Allen boilers do not have any vertical stays on them either, they have the girders on the crown sheet. They are relieved on the bottom to allow water circulation. So are all ...

I was doing some research and was loooking into the strength of material and staybolts. The tensile strengh of 1018 Hot Rolled steel is 69,000#. It takes 28 tons per foot to bend with a 1.5" open V die. In Joe Nelson's book, hey gives a formula for calculating stay bolt diameter. The example he gave...

I spoke with Dan Markoff (owner of the Eureka) over the weekend about boilers. His boiler is the original boiler from the factory in 1875 made from .375" material. The only thing that needed replacement was the front tube sheet. He has the boiler inspected annually and it pases every time. He chuckl...
