Hi

I need to replace a steel tube 1500mm long (25mm OD - not sure yet what ID is) with one that is made from your roll wrapped tube range. The Tube is supported at either end and is loaded along its length. No Torsional forces are acting on the tube.

 My question is: can I simply replace with a CF tube that is approximately 25mm OD? Will this new CF tube be over or under engineered.

Any help or advice would be greatly appreciated.

Without knowing exact weights and dimensions and measuring it, it would be impossible to work out the precise deflection. 

As a rough guide, you can compare carbon roll wrapped tubes to steel equivilents of the same diameter and wall thickness.  You will get roughly the same kind of deflection and performance with the bonus of it being less than half the weight.
