Standard

Specification

Drill pipe is a hardwearing seamless steel pipe that is rotated to circulate the drilling fluid. This pipe is useful for pumping back the drilling fluid back up the annulus. The annulus is the space in the oil well between the casing and the piping. Easy circulation of the fluid within the well is possible because of the Annulus. The api 5dp drill pipe is subject to axial tension since high torque is required for rotating the down-hole assembly drilling the fluid and circulating it. The OCTG drill pipe needs to be extremely strong as they have to bear a high amount of stress underground. The drill pipe is used at the drilling rigs and they are available in different sizes and different qualities.


API 5DP drill pipe is trailing with screw thread for connecting the drilling rig located at the bottom of surface drilling equipment and mill equipment or bottom outlet device. The purpose is to drill the drilling mud delivered to the drill bit, and drill with the increase, decrease or rotating bottom outlet means. Drill pipe must be able to withstand great external pressure, twisting, bending and vibration. In the mining and oil and gas refining process, the drill pipe can be used multiple times.
