45Mn2 CONCRETE PUMP PIPE FOR PM Packing:bundle size :dn125x4.75 Delivery Time :20days Material :ST52

45Mn2  CONCRETE PUMP PIPE

Technology:

This product is made of the special quality steel, after being quenched and carried on the carburizing chemical treatment on the inner wall, the hardness degree of the flanged bushings can reach 58-60 degrees, and the serving life of pipeline can increase by 3-5times, which can enable users save time and costs, remove from the trouble of changing the tube regularly, and enhance the production efficiency.
