Heavy Weight Drill Pipe

DESCRIPTION:
Heavy Weight Drill Pipe (HWDP) is an intermediate weight drill stem component
which is used in conjunction with the drill pipe and drill collars. SCOTON's HWDP is
available in standard, spiral and non-magnetic designs. In some applications,
heavy-weight also can be used instead of the drill collars. Now the integral heavy
weight drill pipe is becoming more and more important in oilfield.
SCOTON heavy Weight Drill Pipe has been awarded by the NS-1 certification which
is made from one-piece 4145H modified quenched and tempered steel. It is designed
for tough drilling environments in vertical and directional wells; for vertical wells,
SCOTON's spiral heavy weight drill pipe is a transition member; for directional holes
it is a weight member and provides additional stiffness to prevent buckling.
