Details of manufacturing


Tool joints are inertia welded to the tubes with computer-monitored precision. Concentricity is carefully monitored and controlled, and the parameters of each weld are electronically recorded, and traceable to each joint.

                                                                                                              














After removal of weld flash, the weld area is austenitized, quenched, and tempered to achieve the required mechanical properties. Heat treat cycles for each weld are compared to specific parameters and recorded for traceability.

                                                                                                              














After all steps and machine marks are polished from the OD and ID area, hardness testing, ultrasonic testing, and wet magnetic particle inspections are used to verify the integrity of each weld zone.
