Questions & Answers
Which method would you use to bend piece of tubing if a tube bender is bot available?
Correct Ans-Sand.
To correctly construct a single flare, you make the outside diameter (OD) Correct Ans-extend
approximately 1/16 inch beyond the end of the sleeve.
For tubing flares to seat properly, they must be Correct Ans-square and concentric.
To properly use the squaring- and burring-head assembly on the power flaring machine to word a
piece of tubing, you position the tubing in a vise so it is Correct Ans-beyond the flaring dies.
While using the squaring- and burring-head assembly on the power flaring machine the probable
cause of more inside chamfer on one side of piece of tubing and more outside chamfer on the
opposite side is Correct Ans-misalignment between the spindle and vise jaw.
To readjust the spindle on a powered flaring machine for another size of tubing, you Correct
Ans-change the flaring center setting to match the OD of the new size tubing.
To remove the tubing after you have finished making a flare with the double-flaring machine,
you move the operating lever Correct Ans-to the no. 1 position, and the push the lever toward
the rear of the machine.

drive screw an additional one-eighth to one-fourth turn
To properly deburr a piece of tubing for a Permaswage repair, you must not allow the chamfer
width to exceed Correct Ans-one-half the wall thickness.
To properly perform a Permaswage operation, you place the silver face of the die holder to a
position that Correct Ans-corresponds with the silver side of the yoke.
Dynatube expanders designed for titanium are identified by a stop collars painted Correct
Ans-yellow.
To properly make a Dunatube repair, you should have what degree of chamfer on the inside
diameter of a tube? Correct Ans-60 degree
