These coolant pipes can be repaired depending on the extent of the damage with aluminum brazing rod and propane or map gas. 
Search on aluminim brazing on Google and you'll have all the info you need.
Here's one site you can try right off the bat.

The other alternative is to cut your replacement hose long and clamp downstream of the damage.
