The electrification of polymer powder transported through straight copper pipe and copper pipes with 45° and 90° elbows (0.02m in internal diameter) was studied at a particle speed ν=7m/s〜30.8m/s and a solid load ρ=0.002 kg/m^3〜15 kg/m^3. The charge/mass ratio q of the powder passing through an elbow pipe was from 15 to 20 times larger than that in a lm-long straight pipe. With elbow pipes, it was found that the charge on the powder Q (C) was mostly generated by the first collision with the inner wall of the bend in the pipe. The impact areas S(m^2) of the particles in the elbow pipes were calculated at low ρ and high ν, and the charge density σ(Q/S C/m^2) was found to be constant in spite of the variation in ρ, ν and the shape of the pipes.
