Durable by design and naturally decorated (at least by modern minimalist standards) with rims, rings, curves and solid colors - and complete with openings in multiple places - a piece of pipe is a natural choice for use as a decorative home object like a flower vase.
This so-called Pretty Vase Collection by Francois Xavier Ballery for Domeau&Pérès is clearly a play on the industrial (non-pretty) nature of the constituent pieces, colorfully converted to new use for furnishing the middle- and upper-class homes of aesthetic eccentrics looking for the latest household trend. Of course, instead of buying the designer version you could probably make your own variant for much much cheaper.
