    How can I prevent deformation of an ultrathin-walled tube during insertion?

    Designing mechanical system where two concentric tubes will pass through high density membrane. Outer tube will have tapered end .Outer tube will have ultra thin walls (about 0.3-0.5 mm) .Inner tube is more rigid and will fill all space inside outer tube,decreasing chance for deformation of...
