Sany Heavy Industry in the draw lessons from the international advanced technology, and after a year of repeated theoretical proof and concrete pumping practice verified, Sany independent research and development of the third generation of high wear-resistant ducts in the user eagerly looked forward to successfully developed . The new pump tube pumping side of the average volume of more than 30,000 square, than the overall life of the traditional pump to enhance 1-2 times. The traditional pipeline are used single-layer wear-resistant steel as raw material, with a special hardening process to enhance the wear resistance of the inner wall. The overall hardening process is complex and difficult to control the specific hardening time, the overall wear resistance of the pipe instability. After hardening process to enhance the wear resistance of the inner wall of the pipe, but it reduces the overall toughness of the pump tube, increasing the fragility of the pump tube so that the pump tube easily broken and cracked. Sany Heavy Industry third-generation high wear-resistant pump tube pump in all aspects than the traditional obvious advantages. The new pump tube with a new double-tube design concept to overcome the "hardened" the traditional pump tube production process complexity, difficult control, instability and negative effects, but the direct use of double design, the use of high Wear-resistant steel pipe to do the original pipe wall, the use of high-toughness steel pipe to do the outer wall of the pump to make up for the traditional pump of the various deficiencies, and fully guarantee the new pump pipe overall stability, wear resistance and toughness. In addition, Sany Heavy Industry new pump pipe in the use of double pipe design, but also the introduction of the most advanced pipe making equipment, fully guarantee the combination of inner and outer pipe precision, reduce the gap between the inner pipe and the outer pipe surface , Thereby reducing the impact vibration to enhance the life of the pipeline.
