The Welded Blade Stabilizers used in the B.H.A for drilling soft to medium hard formation holes are available in three types as shown. Stabilizer bodies are manufactured from AISI 4145 H Modified Steel with mechanical properties in accordance with API Specification 7. Mid steel blades are welded onto the body using strictly controlled pre-heating, post weld heat treatment and weld application techniques. All areas affected by the process of welding are subject to full non-destructive examination to assure the mechanical integrity of the joint. Standard Welded Blade Stabilizers are available in 3 or 4 blade configuration with the spiral type available with open or tight spiral.
