 integral spiral Stabilizers The Integral Spiral Stabilizer is an one-piece tool made of 40CrMnMo alloy steel, then fully heat treated .So their quality, strength, hardness, impact strength are gagged to standard.Three blades of the Stabilizer have been designed to minimize the downhole torque, reduce the damage to the wall of hole and ensure the maximum fluid circulation. When drilling vertical holes, they will be applied to reduce drift of drill bits and keep the drill bit straight downward. When drilling directional holes, they can increase, decrease or stabilize the tilt of the hole, ensure the orientation of the hole, improve the quality of the hole, and increase the drilling speed. Material 40CrMnMo (4145H) Hardness HB 290—340 Strength σb≥965 Mpa (D2<160mm) σb≥931 Mpa (D2>160mm) Impact strength Ak≥54 J(40 ft-bl) Connections conform to API standards. And their Stress relief grooves are cold rolled. Connections are phosphatized or plated copper, coated and equipped with thread protectors. Hardfacing of Blades: Tungsten Carbide Inserts are cold inserted into the area of blades including its beveled. . Through Ultrasonic testing and Magnetic testing the body are proved up to grade. On inquiries and orders Please specify: Hole size and type of stabilizer (string or near-bit). Drill Collar ID and OD. Connections type and size. API stress relief groove. Open or tight design. Right or left hand spiral. Hardfacing type. Float valve and hole.Tubing Power Tong
