Boom. And just like that...

They can't do the work if they don't have the material. The valves we make for the power plant's just can't be purchased off the shelf. Most of the valves that go into paper mills, including their boiler house can be found on the shelf at most valve manufactures and distributors.

Interesting. Just out of curiosity, do you know if there are reasons the power plants couldn't be designed using standard parts and supplies?

I know little to nothing about power plants, but during my years in manufacturing we'd occasionally have to deal with an engineer or three who liked to design new equipment with custom parts and eventually we'd end up redesigning it to use standard parts.

A lot of parts especially for Nuclear Power Plants have to have a paper trail and quality certified from manufacturers.

Pressure and Temperature

Boiler houses in a paper mills don't hit the pressure and temps needed to get into alloys such as C12A or F91. Most of their needs can be met with WCB. Occasionally you'll see a line that needs WC6 and rarely WC9. Which again, even WC9 can be found on the shelf. There are specialty companies that carry some C12A but that's a huge financial burden to carry that inventory. Main steam isolation and non-return valves along with hot reheat valves in a combined cycle plant are C12A due to pressure and temps. Most coal plants operate in a range that WC9 and below are generally acceptable as well. And as Jamey29657 said, if a valve is going to a nuke in and or around the reactor it will have to have an N stamp. But even their standard valves outside of the reactor often require special seismic testing.
