You will need use planes for some of the mating. One tube will need to have
a plane perpendicular to the cut face, and aligned with the longest
dimension of the cut face. If the tube was cut with a cut-extrude, you'll
be able to use that feature's sketch's plane.
First mate the machined faces, then mate the perpendicular plane with the
temporary axis of the body of the other tube.

First, make sure the circles you sketched for your pipe are concentric with
the origin of your part (Let's assume the plane chosen to draw the circles
is the front plane). You then use the right plane to cut extrude your 22.5
deg angle. When this is done, pick the right plane again and after selecting
the edge at 22.5 deg, use the convert entity to get the projection of this
edge on your sketch plane. You can the sketch a horizontal center line and
insert a sketch point at the intersection of your two lines. Exit the sketch
and go in the assembly.
In your assembly, mate the two angled faces coincident as well as the right
planes of both your tubes. At last, make the two sketch points coincident
(make sure view sketches is checked from the view menu)
This is a long description but it's actually quite simple.
Hope this helps

In each pipe part:
Make a sketch on your cut surface of the pipe. Sketch a point and
constrain it concentric with the edge of the pipe (the edge is actually
elliptical, but the concentric constraint works with elliptical edges in
SWX too.)
Now in the assembly:
Mate the cut faces of the pipes Coincident.
Mate the sketch points of each pipe Coincident.
Mate a couple of the part planes parallel to constrain the rotation at
the joint.
Done!!
