Dalian sanlei machinery co., ltd.

Through the joint development and efforts of the technical department and the production department of the three base companies. The third base company adopts new 90/33, 75/33 * * extruders and professional high-speed molding machines for trial production. The production speed of HDPE double-walled corrugated pipe with ID of ID300mm can reach 2.8-3.0 m/min, reaching the international leading level. This production speed is influenced by weather, raw materials and technological conditions. )

On the basis of rigorous scientific theory, through constant argumentation and repeated experiments, Dalian No.3 Base successfully developed the 1.8m PP double-walled corrugated pipe production line, which successfully filled the domestic blank. The project is officially put into production, which will open a new chapter in the history of PP double-walled corrugated pipe production line in China.
