3 1/2" size G-105 grade API drill pipe
3 1/2" size G-105 grade drill pipe
Drill pipe is a portion of the overall drill string which connects the rig surface equipment with the bottom hole assembly and the bit both to pump drilling fluid to the bit and to be able to raise, lower and rotate the bottom hole assembly and the bit. It is a thick walled, hollow, steel piping used for both conventional as well as horizontal drilling.
Brief introduce
Drill pipe is a portion of the overall drill string which connects the rig surface equipment with the bottom hole assembly and the bit both to pump drilling fluid to the bit and to be able to raise, lower and rotate the bottom hole assembly and the bit. It is a thick walled, hollow, steel piping used for both conventional as well as horizontal drilling.
