PREMIUM CONNECTION/ RTN-14AM
STRUCTURE • Featuring a coupling connection type that equals or surpasses the pipe body strength. • Enhanced buttress thread ensures high connecting efficiency and ease of processing. Sizes: 2 3/8"-2 7/8" with 8 TPI, 3 1/2"-4 1/2" with 6 TPI, 5" and over with 5 TPI. • Taper to taper seal structure with a negative angle torque shoulder boosts sealing capability. • Reverse torque shoulder enhances load-bearing connection capacity. • Seamless wall alignment between pipe body and coupling. PERFORMANCE • Achieves connection strength comparable to pipe body strength with standard coupling. • Low angle taper to taper interference seal, fortified by reverse angle torque shoulder, provides high sealing reliability. • The reverse torque shoulder ensures high resistance to compression, bending, and over-torque stresses. • Inner flat design minimizes gas and liquid turbulence, reducing energy loss. • Anti-galling design allows multiple makeup and breakout cycles.

 

PREMIUM CONNECTION/ RTV-200P
STRUCTURE
• Innovative coupling design: Critical cross-sections of coupling surpass those of the pipe body for added strength.
• Features a modified hook thread profile with a -4° reverse angle on the load flank and a 10° angle on the lead flank, delivering superior tension strength and enhanced compression resistance. Sizes: 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, 8 5/8" and up with 4 TPI. • Patented taper metal-to-metal seal system guarantees exceptional gas-tight sealing under severe conditions, such as bending and temperature variations. • Reverse angle torque shoulder provides precise torque stopping, ensuring accurate power-tight makeup and minimizing hoop stresses.
PERFORMANCE• Connection strength rivals that of the pipe body with standard coupling. • Seal property is enhanced by a low angle taper to taper interference seal, reinforced by reverse angle torque shoulder, ensuring exceptional seal reliability. • Hook thread and reverse torque shoulder design offer high resistance to compression, bending, and over-torque loads. • Inner flat design significantly reduces gas and liquid turbulence, optimizing energy efficiency. • The anti-galling feature permits multiple makeup and breakout cycles ensuring long-lasting usability.
