This paper describes the characterization of rigid pipes of polyvinyl chloride (PVC), manufactured with recycled resin derived from industrial waste reprocessing and/or sanitary. The recycled pipe was characterized using the techniques of X-ray Diffraction (XRD), thermogravimetry (TG / DTG), vibrational spectroscopy absorption Fourier transform infrared (FTIR) and tensile testing. The diffraction pattern revealed an essentially amorphous material with small percentages of crystallinity. The infrared analysis showed bands whose positions and their corresponding assignments of the functional groups are in agreement with the values found in literature relative to the axial deformation of the C-Cl bonds and C-H and symmetrical angular deformation out of the plane of CH2-Cl. The results on thermal analysis revealed, only two major events degradation at 265-312°C and 445-482°C. The recycled PVC in this study showed good properties, which is consistent with the
