If you start gently and allow the speed to build up they should be fine. All my frames are foundationless and no wires - I very rarely get any blow outs ...it's about technique .. slowly, slowly build up the speed because it's the weight of the honey that increases exponentially with the rotational gravity thay causes the frames to blow out.
If you have a tangential extractor you need to be a bit more careful - spin out one side very gently, turn the frames, do the other side which you can spin faster (but again starting slowly and building up) and then go back to the first side and spin that at a higher speed to finish the job.
Just be careful and you can 'feel' the point where you can increase the speed.
However, if it's OSR you are spinning out you need to get on with it because it sets like a brick in no time.
