wear-resisting arm support pipe

                        

       
 

This product is made of steel pipe of special material, processed by inner-arm quenching and carburization, to make hardness of flange bushing achieve 58-60 degrees, which improve pipeline life by 3-5 times, save customers’ time and costs by eliminating the trouble of frequent pipe replacement, and improve the production efficiency.
