PREMIUM CONNECTION/ RTN-14AM

STRUCTURE • Our coupling connection type boasts strength that meets or surpasses that of the pipe body. • Features improved buttress threads for high connecting efficiency, ensuring easy processing. Sizes include: 2 3/8"-2 7/8" with 8 TPI, 3 1/2"-4 1/2" with 6 TPI, and 5" and over with 5 TPI. • The main seal uses a taper-to-taper structure with a negative angle torque shoulder to boost sealing capability. • Enhanced reverse torque shoulder optimizes load-bearing connection capacity. • Pipe body inner wall aligns seamlessly with the coupling inner wall. PERFORMANCE • Connection strength rivals that of the pipe body even with standard coupling. • Seal property: Advanced taper-to-taper interference seal, enhanced by the reverse angle torque shoulder. • Multi-seal configuration ensures top-notch reliability. • Reverse torque shoulder provides exceptional resistance against compression, bending, and over-torque. • Inner flat design mitigates gas and liquid turbulence, reducing energy loss. • Anti-galling design allows multiple makeup and breakout processes.

PREMIUM CONNECTION/ RTV-200P

STRUCTURE

• Coupling design: Features critical cross sections greater than those of the pipe body, delivering superior performance.

• Utilizes a modified hook thread profile with a -4° reverse angle on the load flank and a 10° angle on the lead flank, offering superior tension strength and enhanced compression resistance. Sizes include: 2 3/8"-2 7/8" with 8 TPI, 3 1/2"-4 1/2" with 6 TPI, 5"-7 3/4" with 5 TPI, and 8 5/8" and up with 4 TPI. • Our patented taper metal-to-metal seal system ensures exceptional gas-tight sealing, even under severe load conditions such as bending and temperature fluctuations. • The reverse angle torque shoulder provides a precise torque stop for accurate, power-tight makeup while minimizing hoop stresses.

PERFORMANCE• Connecting strength: Achieves the robustness of the pipe body with standard coupling. • Seal property: Boasts an advanced taper-to-taper interference seal, further enhanced by the reverse angle torque shoulder, ensuring high seal reliability. • The hook thread and reverse torque shoulder enable the joint to withstand compression, bending, and over-torque. • Inner flat design reduces turbulence of gas and liquids, minimizing energy loss. • Anti-galling design supports multiple makeups and breakouts, enhancing usability.
