About us

We specialize in producing and selling API standard drill pipe from 2-3/8''OD to 5-1/2''''OD.with steel grade E75,X95,G105,S135.We can supply both NC,IF,FH connection type and special connection type as HT55.Mainly used in oil and gas exploration and development process of deep well,horizontal well and extended reach well.

Drill pipe is a portion of the overall drill string. The drill string consists of both drill pipe and the drill stem which is the tubular portion closest to the bit or downhole assembly. Drill pipe and drill stems can be differentiated in that the drill pipe is quite flexible and produced in longer segments whereas the drill stem is much more rigid and manufactured in shorter task specific segments.
