The wholly coated drill pipe makes the drilling speed (Rate of Penetration) a few times faster under the usual RPM and drill mud pumping rate, for various formations. It is due to the 80% reduced drill pipe surface friction that the coating stays after drilling hundreds of kilometers. Hard banding is no longer needed. There will be much less threads wear and swollen connections when the whole drill pipe string is coated (threads are coated, with no specific torquing restriction). No more internal corrosion that currently is protected by internal plastic coating which does not provide a sound protection. Less heavy weight drill pipe joints, and less sleeves/friction reduction tools will be needed. The coated full string drill pipe expedites the ultra deep drilling as well.

The application is for long term use where high pressure hydrogen and helium are operated. Successful applications and lab tests have been done. Under high pressure hydrogen, an uncoated carbon steel material would lose 40-50% strength in 2 weeks.
