Ah, OK, the "pipe"...
I would think that you could replace the pipe from independent sources with similarly-sized metal pipe material cut to length. It should be a matter of measuring, finding a source, and duplicating the attachment method at both ends (perhaps with the aid of an independent machine shop). Then it can always be primed and painted white to match rather than chromed. I find that many things on a boat can be replaced with items from "non-nautical" sources of equal, or better, quality, and at a fraction of the cost...
