Working on the Railroad, page 4

On May 19, 2009 we reached a major milestone, the boiler for #9 was finished and ready for its final inspection. The inspector representing the ASME came in and watched us conduct a hydro test of the boiler. This consisted of plugging all the boiler connections, filling it with waster and pressurizing it to 150% of working pressure- that's 210 psi for this boiler. We held it at that pressure as the inspector went over it carefully for any signs of leaks or problems, then reduced to working pressure of 140 psi. We held it there about an hour while he continued to look it over very carefully.

Once the hydro was complete he proceed to very carefully examine piles of paper work. A certified boiler must be made of all certified material, and every item that went into the boiler had to have a paper trail with vendor info and a statement of the standards it met. This process started when the boiler was started and was checked at every inspection point.

Finally the inspector was satisfied and allowed Brian to apply the official Stamp

Here Brian carefully lines up the stamp.

And then Brian and Jason examine the stamp

I made this brass builders plate to carry the official stamp and the serial number.
