Products description

1.Kelly bars are key components in the execution of boreholes with hydraulic rotary drilling rigs. They transfer the torque of the rotary drive and the crowd pressure of the crowd system concurrently to the drilling tool. A Kelly bar consists of 2 – 5 telescopic tubular sections with a system of drive keys and lock recesses, welded onto their outer surfaces.

2.We have innovatively added a reinforcement ring structure for each terminal joint, which is heat-treated to effectively reduce the risk of cracking the pipe during drilling.

3.Interlocking kelly bars are indeed provided with drive ribs which are welded with lock devices in order to transfer the maximum torque to each scope. To make sure to transfer the maximum torque over the full extended length.
