A) Integral Blade Stabilizers
Alloy stabilizers
are manufactured from AIASI 4145 H Modified steel, fully heat treated to 285-341
Brielle hardness and 40 ft. IBS. Min. IZOD impact strength.
The blades spiral milled in either left hand (L.H.) or right hand (R.H.) in
three main
Configurations:
• Open (to 210°)
• Tight (to 270°) 7
• Wrap-Around (to 360°)
The spiral blades are machined to provide maximum mud circulation.
Connection features are:
• Bore back box stress relief pin cold rolled thread roots
• Phosphate coated
• Pressed Steel thread protection are standard
Blade diameters are ground to maximum of “1/32" under gauge on all hole sizes
Hard-faceting is applied on the leading edge as an additional protection.

B) Welded Blade
& Sleeve-Type Stabilizers
Replaceable Sleeve Stabilizers are designed to reduce inventory problems by
offering complete thread interchangeability with your Servo type 2 mandrels and
sleeves. The sleeve is a one-piece casting designed for easy make-up to the
One-piece mandrel. The mandrel is made from A.I. S.I. 4145 H modified alloy
steel or non-magnetic steel.
Standard Weld Blade Stabilizers used in the B.H.A. for drilling soft to medium
hard formation holes are available in three types. Stabilizer bodies are
manufactured from A.I.S.I. 4145 H modified steel with mechanical properties in
accordance with A.P.I. Specification 7.
Mild steel blades are welded onto the body using strictly controlled
pre-heating, post weld heat treatment and weld application techniques.
All areas affected by the process of welding are subject to full non-destructive
examination to assure mechanical integrity of the joint.
Standard Weld Blade Stabilizers are available in 3 or 4 blade configurations
with the spiral type available with open or tight spiral.
Thread connections are manufactured to A.P.I. Specification 7 and can be
produced with Stress Relief Groove and Bore Back according to customer's
specification.
