Drill Collar is the basic component in the BHA
which provides weight on the bit for drilling and
keeps the drill string in tension.
Fengliang Drill Collar is manufactured from
AISI 4145H modified quenched and tempered
steel and is heat treated along its entire
length for uniform toughness and durability.
Strict metallurgical tests are performed per
specifications to ensure that the heat treatment
produces consistent and maximum hardness
through the depth of the bar.
Features and Benefits
● A hardness range of 285 to 341 BH N
and a Charpy impact value of 40 lbs/ft are
guaranteed for evenly distributed 16 points in
any cross sections at room temperature;
Specifications - Drill Collar
● Connections are phosphate coated after
machining to protect the threads from
corrosive elements and to prevent galling
upon initial make-up;

Heavy Weight Drill Pipe (HWDP) is an
intermediate weight drill stem component
which is used in conjunction with the drill
pipes and dril l collars. TIAnHE HWDPis
available in standard, spiral and non-
magnetic designs. In some applications,
heavy-weight drill pipes also can be used
instead of the drill collars.
Fengliang HWDP is made from one-piece AISI
4145H modified quenched and tempered
steel. It is designed for tough drilling
environment in vertical and directional wells.
Fengliang HWDP is a transition member
between drill collar and drill pipe. For
directional holes HWDP provides weight-
on-bit and additional stiffness to prevent
buckling.
