Oil processing special-purpose temperature-resistant pressure-resistant circumferential self-reinforcing plastic pipe forming device

The invention relates to a device for producing and manufacturing various plastic pipe products..The device is characterized in that it comprises a segment temperature controllable temperature gradient field generating apparatus and a circumferential shear stress field generating apparatus; and can realize the pipe-extruding forming technology by coupling the temperature gradient field and the circumferential shear stress field; the plastic pipes prepared by the device of the invention has the advantages of circumferentially enhancing the pipe intensity and modulus, more optimally allocating the material performance, improving the satisfaction of the material performance implementation requirement to the pipes internally extruded. Thus the enhanced pipes has higher circumferentially oriented degree, higher wafer thickness and higher degree of crystallization than conventional pipes; thereby achieving higher emperature toleration than the conventional pipes; and is especially suitable for using as oil processi
