Stabilizer (CDST)

Stabilizer Product Details: Certification API Machine Type Drilling Equipment Type Stabilizer Oil drilling Drilling pipe Use Well Drilling Processing Type Casting Material Stainless Steel STABILIZER Four designs are available as below: 1) Integral spiral type The Integral spiral stabilizers are made from AISI 4145 H Modified alloy steel or Non-magnetic alloy steel, the pressed button type or applied tungsten carbide hard faced on the blade. 2) Intgral straight rib stabilizer 3) Interchangeable sleeve stabilizer Interchangeable sleeve stabilizers are made of 4145 H Alloy steel, heat-treated to 285-341 Brinell Hardness and 54 Joules minimum impact value. All physical properties would be guaranteed 1" under the surface. The stabilizer is constructed of two pieces, which are jointed, by the center mandrel and one sleeve.STANDARD SIZE OF INTEGRAL SPIRAL STABILIZER Hole Size (in) Standard DC Size Wall Contact Blade Width Fishing Neck length Blade Overall length(in) Weight (in) (in) (in) (in) under-gauge (in) String Near Bit (lb) 6-6 3/4 4 1/2-4 3/4 I 16 2 1/4 28 -0.03125 74 70 363 7 1/2-8 1/2 6 1/2 16 2 1/2 28 -0.03125 75 70 770 9 1/2-12 1/4 8 18 3 1/2 30 -0.03125 83 78 1650 14 3/4-71/2 9 1/2 18 4 30 -0.03125 92 87 2204 20-26 9 1/2 18 4 30 -0.03125 100 95 3960 Mechanical Properties for stabilizers OD Tensile Strength (Mpa) Yield strength (Mpa) Elongation (%) Reduction of area (%) Impact (J) 4 3/4-6 1/4 >=965 >=758 >=13 40 >=54 7-9 >=931 >=689 >=13 40 >=54 Mechanical Properties for Sleeve >=735 >=539 >=13 30 >=47 Hole size (in) DC Size (in) Upset Bottom Neck Overall Fishing neck length (in) Weight (Ib) Sleeve Diameter (in) Dia.
