Welded Blade Stabilizer

JA Oilfield’s Welded Blade Stabilizer is primarily used in soft to medium formations. Industry standards for welding downhole drilling tools are strictly followed to ensure operators of superior weld integrity of the blades to the stabilizer body.

Stabilizer bodies are manufactured from 4145H modified, quenched and tempered material. They are pre and post-heated to assure weld penetration. Bodies are ultrasonically and mag-particle inspected for cracks and flaws.

Extra long and wide blades are used for better stabilization. Both spiral and straight blade configuration are available at the user’s request. Bodies can be dressed with a 3 or 4 blade design.
