The features of TYSIM High quality rotary drilling rig use interlocking kelly bars

  • Adopt the advanced technology of 6-key design in the world and standard modular design.
  • Equipped with advanced processing facilities, workmanship and manufacturing equipments,  kelly bar enjoys a low weight, high strength, high straightness of single bar, thinner tube, smaller inter-tube distance and good abrasion resistance.
  • 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.
  • All the outer keys have undergone special heat treatment; therefore, they possess higher hardness, higher flexibility and excellent welding properties, which provide higher abrasion resistance to the keys.
2) Friction Kelly Bar
Friction Kelly bar is another type kelly of bar ,which the external key is composed of 3 or 6 wear -resistant strip without pressunrizing point .This kelly bar can form pressure force when the kelly bar is rotary.can produce peripheral force and the rotary passing down the pressure force,can produce the friction force.This kelly bar has the advantage of opeerating sample .drilling deep ,but with less pressure transmission.So this kelly bar is suitable for the soft and silt laye.
