High Torque Innovation
MAXIMUM TORSIONAL STRENGTH- Is Everything You Know About INTERLOCK; Innovative Semi Premium Connections.
INTERLOCK® COUPLED SLIM LINE MAXIMUM TORSIONAL STRENGTH
THE SLIM LINE IS A VIABLE ALTERNATIVE TO EXPENSIVE SEMI FLUSH. THE OUTER DIAMETER IS SMALLER THAN API SPECIAL CLEARANCE COUPLINGS.
HIGH TORQUE - REPLACES THE NEED FOR HIGH TORQUE SEMI FLUSH
The INTERLOCK® uses flank locking dovetail threads to counteract high torque loads. It is an ideal cost effective replacement for semi flush. It can be threaded without special swaging equipment. It is immune to the heat treat and stress relief problems of semi flush.
Details
- SMOOTH SLIM OD PROFILE: Perfect for special clearance applications requiring high torque. Perfect for 6-3/4″ Hole with 5.5″ pipe.
- 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 deeply. 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.

The design difference
This specialty semi premium connection was engineered specifically for horizontal shale service. The INTERLOCK® COUPLED SLIM LINE connection was designed to withstand higher torques, severe bends and higher frac pressures.
MAX TORQUE. MAX PRESSURE.MAX CLEARANCE
With the new INTERLOCK® COUPLED SLIM LINE 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.
