IMT Kelly Bar For Rotary Drilling Rig Spare Part
Advantages of the IMT Multi-Lock Kelly Bar
In short, here are some of the advantages that the IMT Multi-Lock Kelly Bars offer, as opposed to the standard J-lock Kelly bars:
1.The rotary on the kelly bar can be locked at any point, undoubtly resulting in better flexibility.
2.It completely eliminates the “friction drilling”. As have been noted, friction drilling is the time that the rotary is sliding down the kelly bar canister without being locked. Therefore, production is increased.
3.Ability to transfer the entire constant crowd force to the drilling tool, hence maximizing efficiency.
4.Obviously, multiple locks will significantly improve the life of the whole kelly bar. As a result, the even distribution of forces and momentum ensure the IMT kelly bar durability and reliability.
5.Steel strength. IMT Kelly Bars are made of special type steel with strengths graded at 1000 MPa.
6.Canister thickness. IMT uses a thickness of 12.5 mm for the outer element, instead of 10 mm, therefore making it more resilient in time.
7.Canister length. IMT manufactures their kelly bars using three tiles of 1 metre each, for the purpose of strengthening and increasing the durability of the tube.
