We study DBI-type effective theory of an unstable D3-brane in the backgroundmanifold R^{1,1} x M_2 where M_2 is an arbitrary two-dimensional manifold. Weobtain an exact tubular D2-brane solution of arbitrary cross sectional shape byemploying 1/cosh tachyon potential. When M_2=S^2, the solution is embedded inthe background geometry R^{1,3} x S^2 of Salam-Sezgin model. This tachyonpotential shows a unique property that an array of tachyon soliton solutionshas a fixed period which is independent of integration constants of theequations of motion. The thin BPS limit of the configurations leads tosupertubes of arbitrary cross sectional shapes.Comment: 15 pages, 1 figure, LaTeX2e, minor changes, version appeared in JHE
