We present a detailed study of the two-parton light-cone distribution amplitudes for 1(3)P(2) nonet tensor mesons. The asymptotic two-parton distribution amplitudes of twist-2 and twist-3 are given. The decay constants f(T) and f(T)(perpendicular to) T defined by the matrices of nonlocal operators on the light-cone are estimated using the QCD sum rule techniques. We also study the decay constants for f(2)(1270) and f(2)'(1525) based on the hypothesis of tensor meson dominance together with the data of Gamma(f(2) -> pi pi) and Gamma(f2' -> K (K) triple over dot and find that the results are in accordance with the sum rule predictions.
