PREMIUM CONNECTION/ RTN-14AM

STRUCTURE • Featuring an innovative coupling connection type that matches or exceeds the pipe body strength. • Enhanced buttress thread ensures exceptional connecting efficiency and effortless 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 enhances sealing capability. • Reverse torque shoulder boosts load-bearing connection capacity. • Seamless wall alignment between the pipe body and coupling. PERFORMANCE • Achieves connection strength comparable to the pipe body strength with standard coupling. • Low angle taper to taper interference seal, strengthened by reverse angle torque shoulder, offers high sealing reliability. • The reverse torque shoulder provides 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, ensuring longevity.

PREMIUM CONNECTION/ RTV-200P

STRUCTURE

• Pioneering coupling design: Critical cross-sections of the coupling surpass those of the pipe body for unmatched strength.

• Featuring an advanced 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 ensures exceptional gas-tight sealing under severe conditions such as bending and temperature variations. • Reverse angle torque shoulder offers 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, backed by reverse angle torque shoulder, ensuring outstanding 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.
