DINO VAM joint is a cost effective T&C connection for surface and intermediate casing applications. DINO VAM connection was specifically designed to reduce rig operating costs by providing running reliability through deep stabbing, no cross-threading and quick make-up. This connection provides sealing with coarse 3 TPI tapered hooked threads. It is immune to jump-in / jump-out.

• A make-up arrestor positions the coupling accurately on the mill end.
• Pin to pin torque shoulder for positive torque stop on the field end allows overtorque and compression resistance.

• Modified hook thread profile, with -9° reverse angle on the load flank and +20° on the stabbing flank which provides superior load carrying performances.
• Increased thread taper, combined with a wider thread profile allows deep and efficient stabbing with no cross threading.
• Increased thread pitch to reduce make-up time.
• Jump-out free.
• Special thread design to offer superior thread sealing performances.

• Vanishing threads, fully covered.
• 100 % tensile efficiency for all sizes standard API Buttress OD.

• Pins shoulder, thereby providing a smooth bore ID to minimize turbulence and energy losses.
• Pins shoulder, thereby providing high compression resistance and immunity to jump-in.

• High stabbing efficiency tolerant to misalignment and suppressing cross-threading.
• Make-up torque tolerance ± 15 %.
• No galling after repeated make-ups and break-outs.
• Half the turns of API Buttress required for make-up

The advanced design of the DINO VAM joint was thoroughly tested on a rig and the benefits verified.
