If you can get hold of a stud finder, or just use a small nail to find the center of your ceiling joists, mark them and drill for what we call "eyebolts". You screw them right into the joists, and slip your pipe through short lengths of chain, that go up to the eyebolts and are bolted to them with bolts, nuts, and washers. Put fingernail polish on the threads for threadlock. Very neat, strong. The holes can later be filled with spackling compound using a putty knife, then painted over.
edit: use a 3/8" eyebolt and drill with a 9/32" drill bit.
