Features:

The raw materials are either imported from Germany like the high abrasion resistance materials, or from Chinese top manufacturer such as the seamless steel tube with alloy. All the tubes made in China are specially made seamless alloy tube, which guarantees the accuracy of the sizes, location, physical properties and easy welding. The small-diameter tubes undergo reheat treatment. The friction kelly bar can be used under full torque.
