Answer to Question 1

R-22 293 psig = 129F saturation
129F  4F = 125F liquid line temperature

Answer to Question 2

In refrigeration work the common flat file and the half round are used in preparing tubing for soldering by squaring the end or for removing burrs. Vises are used to hold tubing or pipe while cutting or threading operations are taking place.
