5.5 inch 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. |
