Worldwide Kelly Drilling Technology Interlocking Kelly Bar
A rotary kelly bar  is used between the rotary drilling rig and the rotary dril ling tools  to transmit torque, axial pressure and other loads. It is a tubular structure that expands and contracts section by section along a common axis.   It   consists of several sections of steel pipes with different diameters and internal and external keys.

What parts does a complete rotary kelly bar  consist of?
1. Kelly eye : It is a component that connects the kelly bar and  the lift ing unit .
2. Bolt: Fix the flange .
3. Baffle: It can prevent the kelly bar  from being carried when the kelly bar  is lifted.
  1. D amping rubber: reduce the impact on the rig  during drilling and protect the rig .
  2. External key: used to transmit torque and pressure, and play a guiding role.
6. Taper  key: play a guiding role and facilitate the pressurization and unlocking  the block .
7. Press ure block : used to transfer pressure.
  1. Pallet : Flowing water protects the end of the kelly bar .
  2. Spring: play a dual role of protecting the kelly bar  and the rig .
10. Kelly stub : transfer pressure and torque to the drill ing tools .
11. Retaining ring: play a role of limiting and positioning.
12. Swivel: positioning, wear-resistant.
13. Internal key: used to transmit torque and pressure, play a role in positioning and guiding.

Kelly bar types as below:
Rotary kelly bars  are mainly divided into two structural forms: friction kelly bars  and  interlocking kelly bar .
The f riction kelly bar  refers to the  kelly bars  through which the shaft pressure is transmitted between the layers of pipe  through friction when the rotary drilling rig is drilling. The f riction kelly bar  has the characteristics of simple operation and large drilling depth. It is mainly suitable for soft ground construction, such as clay, silt, silty soil, artificial backfill and stratum containing some pebbles and gravel .
The interlocking kelly bar  refers to When the rotary drilling rig is drilling, the kelly bar  that transfer pressure between each layer of pipes  through the pressure lock block. The operation of the  interlocking kelly bar  is relatively complicated, and the drilling depth is relatively shallow. However, t he interlocking kelly bar  can transmit a larger pressure through the pressure point and can be used for drilling in rock formations, such as strong weathering, moderate weathering, and slightly weathering  rock formation.

Production of kelly bar:
A good kelly bar  must undergo rigorous testing from material selection to welding to assembly. The quality of our kelly bar  is reliable. The raw materials of key components such as steel pipes, key s  and kelly stub  are all customized from well-known domestic manufacturers. The steel has high purity and quality assurance; strong comprehensive capabilities such as torsion, compression and vibration resistance; Excellent grinding performance and long service life.

Our kelly bars at construction sites:
  1. Technologists '  regular investigation on construction sites promotes product optimization and innovation.
  2. RIGPA kelly bar with high and stable quality has been highly recognized by the customers, and widely introduced to other customers.
  3. Tips for rotary drilling rig working:
  1. The site must be leveled, secure, and determined by the ethanol level on the rotary drilling rig and work experience inspection as the standard.
  2. If the infield is made into holes, blind piles or geological soft belts, signs must be set.
  3. When working in rainy seasons, there must be countermeasures for drainage pipes on the spot.
