T15
Another consideration prior to flanging is the minimum
straight length to the start of a 90° bend. Table T11 provides
this information.
Flange Inspection
The flange should be inspected for proper diameter and sealing
surface quality. Table T12 provides the flange diameters for the
different sizes. The sleeve can also be used as a quick gauge
of the flange diameter. Visually compare the flange diameter to
the tapered surface located at the front end of the sleeve (right
behind the flange). The large diameter and small diameters at
each end of this surface serve as the maximum and minimum
flange diameter limits, respectively.
Notes:
* L is the minimum straight length to the start of tube bend.
** L1 is the minimum centerline dimension necessary for 90°
bent tube to clear the frame of the 1040 machine.
In bending of the tubes, use radius blocks which will en-
sure that L1 dimensions are met or exceeded.
