Temperature instruments shall be flanged, in low-pressure service (600# and lower) RF size 1,

and for 900# and higher the temperature instruments shall be flanged RTJ, size 2. Minimum pipe-run size for temperature connections is 4. For pipe-run sizes smaller than 4, the line

shall be swaged up to 4 to allow temperature instrument connection.

Drain and vent connections on piping shall be NB as a minimum.

Tubing and Compression connections are out of the scope of this specification.

Tubing and Construction fittings used on instrument connections shall be Swagelok type NPT xImperial tube size.
