Questions about this item

What does the 2900 psi rating mean when the union is installed in a piping system?

The 2900 psi rating is the maximum working pressure at 100 °F; at higher temperatures the allowable pressure drops according to the material's pressure-temperature curve.

How does the socket-weld connection limit the pressure the joint can handle?

The socket-weld end conforms to Class 3000 dimensions, so the joint is rated to the same 2900 psi at 100 °F as the union body.

What pipe size and schedule does this union require for a proper socket-weld fit?

It is made for 1-inch pipe and matches Class 3000 socket dimensions, so the pipe bore must correspond to that schedule.
