Stabilizer with rollers (rotary reamer)/ tricorn reamer Rotary reamer is designed for various reams in drilling operation. Especially it can perform the double functions of centralization and reaming when drilling in very abrasive formations. This is a versatile tool which can be used for different hole sizes ranging from 4-5/8·=to 26·=by selecting proper rollers and simply adjust the blocks. In addition, its service life can be extended by replacing new rollers when the old rollers are worn and become smaller. The body is made of modified alloy steel, fully heat treated to 285f+341 brinell hardness and 54j minimum impact strength. Connections are phosphated, coated with thread dope and equipped with thread protectors, and are accord with api standard. Three different types (t, f and b) of rollers are offered: Type t: milled, machined with sharp hard faced teeth, for soft formations. Type f: milled, machined with flat hard faced teeth, for medium hard formations. Type b: equipped with pressed-in tungsten carbide buttons, for hard formations. Sea worthy package
Stabilizer blank Forgings made from AISI 4145H or AISI 4145H Modified for stabilizers. Heat treated and machined as requirements from the customer. Can be with or without spirals. Size: Up to 26 working OD Material: AISI 4145H Mod, AISI4145H or under requirements. After heat treatment and machining, the Hardness is HB290-340, Strength is b b 965 Mpa (D2 160mm) b b 931 Mpa (D2 160mm) Impact strength is AK 54J. We inspect every piece by cutting a piece from its body, every forging should have an inspection report with delivery. Stabilizer with Hardfacing & thread The Stabilizer manufactured by our factory has three types according to its body/mandrel, The mechanical performances of the stabilizer are complied with API Spec.7.: 1.Integral Blade Stabilizer 2.Interchangeable Sleeve Stabilizer. The body (or mandrel) is made of modified alloy steel, and fully heat treated for prospective hardness, strength and impact strength. Through ultrasonic testing and magnetic testing, it is proved up to flowing grade. Material 40CrMnMo(4145H) Hardness HB290-340 Strength b b 965 Mpa (D2 160mm) b b 931 Mpa (D2 160mm) Impact strength AK 54J. The connections are up to API standard which have stress relief grooves and are cold rolled. The flank of thread is phosphatized or plated copper, coated with thread dope and equipped with thread protectors. It is mainly the spiral blades (usually three blades, also can be four blades under the customer's require) , which rub against the borehole wall. The working surface of the blades is hard faced. The hardfacing type we can provide are HF1000, HF2000, HF3000, HF4000. It is preferred operation that tungsten carbide inserts are cold inserted into the working surface of blades including its bevels. Braze welding tungsten carbide grains are also adopted according to customer's require.
