 STABILIER with THREAD & HARDFACING

Standard: API 7, NS-1, DS1

 

Connection: API Regular, PAC, H90

the Stabilizer manufactured by our factory has three types according to its body/mandrel:

 

1.Integral Stabilizer

 

2. Integral Mandrel Sleeve Stabilizer

 

3. Two Piece Mandrel 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 (D2160mm)      b b≥931 Mpa (D2160mm)

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 customers' require), which rub against the borehole wall. the working surface of the blades is hard faced. 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 customers' require.

 

the mechanical performances of the stabilizer are complied with API Spec.7.

on inquiries and orders please specify:

1.Hole size and type of stabilizer (string or near-bit);

2.Drill collar ID and OD;

3.Connections type and size;

4. API stress relief groove;

5. Open or tight design;

6. Right or left hand spiral;

7. Hard facing type;

8. Float valve and hole.

 Integral Spiral Blades Stabilizer

 

Based on the installation place,

this stabilizer can be divided

into two types:String type

and near-bit type.

Built with inserted round carbide in spiral ribs,the product is outstanding by its high hardness, good toughness and powerful wear resistance, as well as its long service life.

U Integral Mandrel Sleeve Stabilizer

Changeable sleeve stabilizer has the same functions as whole sleeve stabilizer. the difference is that it can be used in various well diameters by changing different bearing sleeves. by changing a same bearing sleeve can also extend the using life of stabilizer.
