High Torque Innovation

MAXIMUM TORSIONAL STRENGTH-  Is Everything You Know About INTERLOCK; Innovative Semi Premium Connections.

INTERLOCK® COUPLED MAXIMUM TORSIONAL STRENGTH

WITH OUR TORSIONALLY RUGGED CONNECTOR, INTERLOCK KEEPS YOUR COMPLETIONS ON TIME, EVERY TIME.

HIGH TORQUE - FAST MAKEUP

The INTERLOCK® uses flank locking dovetail threads to counteract high torque loads. It has a deeper stab and makes up in half the number of turns of an API buttress.

Details
  • OVER-TORQUE: The INTERLOCK® COUPLED features better over-torque characteristics which keeps the coupling intact and provides a better chance of drift-ability past yield.
  • LOW HOOP STRESS: Knowing that hoop stress in a slightly salty, acidic, or sour environment is detrimental, due to its low hoop stress, an INTERLOCK® will remain intact.
  • DURABLE SEALING: The dovetail thread handles higher bending loads and structural comprehensive loads while maintaining its seal.
  • DEEP STAB AND FAST MAKEUP:  Fewer threads per inch and a steeper taper allow the INTERLOCK to make up quickly and stab depply. The threads are flat crested which reduces cross threading and binding on makeup by 75%.

100% SEALING CAPABILITY

The dovetail threads make full contact on all surfaces for maximum sealing. Internal and external pressure ratings match API pipe body ratings. A low hoop stress design makes it perfect for high pressure fracking.

100% TENSION & COMPRESSION

The INTERLOCK® COUPLED connection provides 100% tensile and compressive strength on thicker and higher yield pipe; Pin Nose to Pin Nose contact at operational torques for high performance during downhole rotation.

The design difference

This specialty semi premium connection was engineered specifically for horizontal shale service. The INTERLOCK® COUPLED connection was designed to withstand higher torques, severe bends and higher frac pressures.

MAX TORQUE. MAX PRESSURE.

With the new INTERLOCK® COUPLED connection, you get low hoop stresses in critical areas to resist fatigue from rotating and bending under high torque, and 100% tensile and compressive strength on thicker high collapse pipe.

THE INTERLOCK 

IT'S TIGHTER

Designed to retain high-performance sealing after rotating and fracing.

IT'S SAFER

Tested and sealed tight, preventing the leakage of well-bore fluids. 

IT'S STRONGER

Stronger than the pipe body.  Designed for bending, rotating and reciprocating through horizontal sections.
