Application of product: 
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.

A hardness range of 285 to 341 BHM and a minimum impact value of 54 Joules as per ASTM A 370 are maintained one inch bellow the surface at room temperature. To improve resistance to galling, all connections are phosphate-coated with an API thread compond. Each bar used to manufacture kellys has been examined with magnetic partice inspections and ultrsonic inspections.
