  • Apparatus and methods for heating and quenching tubular members
    Patent number: 11473161
    Abstract: A device for heating and quenching a tubular member has a central axis. The device includes a first quenching ring, a second quenching ring axially spaced from the first quenching ring, and a heating ring axially positioned between the first quenching ring and the second quenching ring. Each quenching ring and the heating ring is configured to receive the tubular member. The heating ring is fixably coupled to the first quenching ring and the second quenching ring. The heating ring includes an induction coil configured to heat an annular target zone along the tubular member. The first quenching ring is configured to deliver a first quenching fluid to the target zone and a first annular heat affected zone along the tubular member, and the second quenching ring is configured to deliver a second quenching fluid to the target zone and a second annular heat affected zone along the tubular member.

  • Wellbore tubular air quenching
    Patent number: 11198919
    Abstract: A system for air quenching a heat treated element comprises a tubular component, an internal air quench device moveably disposed within the interior of the tubular component, and an external air quench device moveably disposed about the tubular component. The internal air quench device comprises a nozzle configured to induce an airflow within the tubular component. The external air quenching device can comprise an annular ring disposed about the tubular component that is configured to generate a cone of air about the tubular component.
