China pipe production technology attracts worldwide attention. At present, China can supply the domestic and overseas markets a full range of pipeline products, such as lead-in pipes, corrugated pipes, laminated tubes, aluminum / plastic pipe, PEX, pipes for cold / hot water pipes for the supply / discharge of a paid water, electrical cables and wiring, pipes with very high molecular weight, porous pipes, as well as sound-absorbing sewers. Technical innovations in extrusion made in China can be argued that universal extruders and production Chinese production lines were recognized by the international market for their inherent outstanding cost-effectiveness ratio. In recent years, China has launched a complete range of innovative extruded products, which are produced on the basis of advanced extrusion technology. Innovative technology trehshnekovogo compounding Beijing University of Chemical Technology and South China University of Technology have developed innovative trehshnekovye extruders with its own characteristics.

In 2000, Beijing University of Chemical Technology began research and development of fully trehshnekovyh extruders coupled triangular configuration. In August and December 2005 were created industrial prototypes with diameters of 60/20 and 65/24, respectively, which were tested and were put into trial production. In compared with the twin-screw extruders with similar parameters completely screw extruders coupled trehshnekovye triangular configuration provide a greater area of engagement, thus doubling the frequency of shift to melt. For trehshnekovyh extruder characterized by a wide range of distribution of maximum shear rate. As for the distribution shift trehshnekovye extruders have a greater capacity for dispersion and mixing in comparison with the twin-screw extruders.
