PREMIUM CONNECTION/ RTN-14AM

STRUCTURE • Incorporates coupling connection type that meets or exceeds pipe body strength. • Enhanced buttress thread guarantees high efficiency in connection and easy processing. Available Sizes: 2 3/8"-2 7/8" with 8 TPI, 3 1/2"-4 1/2" with 6 TPI, 5" and above with 5 TPI. • Seal structure with negative angle torque shoulder boosts sealing capacity. • Reverse torque shoulder enhances load-bearing capacity. • Seamlessly aligns the wall between pipe body and coupling. PERFORMANCE • Matches connection and pipe body strength with standard coupling. • Low angle taper seal fortified by reverse angle torque shoulder for high seal reliability. • Reverse torque shoulder ensures high resistance to stresses. • Inner flat design reduces gas and liquid turbulence, conserving energy. • Anti-galling design supports multiple makeup and breakout cycles.

PREMIUM CONNECTION/ RTV-200P

STRUCTURE

• Innovative coupling design: Critical cross-sections surpass those of the pipe body, enhancing strength.

• Modified hook thread profile with a -4° reverse angle on load flank and 10° on lead flank, delivering superior tension and compression resistance. Available 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 above with 4 TPI. • Patented taper metal-to-metal seal ensures exceptional sealing under harsh conditions. • Reverse angle torque shoulder ensures precise torque stopping, minimizing stresses.

PERFORMANCE• Connection strength matches that of the pipe body with standard coupling. • Seal property is heightened by a low angle taper seal, reinforced by reverse torque shoulder for superior reliability. • Hook thread and reverse torque shoulder design resist compression, bending, and over-torque. • Inner flat design reduces turbulence, maximizing energy efficiency. • Anti-galling feature supports multiple makeup and breakout cycles for longevity.
