PREMIUM CONNECTION/ RTN-14AM
STRUCTURE • Experience superior coupling connection types that rival or exceed pipe body strength for unmatched performance. • Enjoy enhanced buttress threads that ensure high-efficiency connections and simplify processing. Sizes range from 2 3/8"-2 7/8" with 8 TPI, 3 1/2"-4 1/2" with 6 TPI, to 5" and over with 5 TPI. • The innovative taper to taper seal structure, paired with a negative angle torque shoulder, dramatically improves sealing capabilities. • Reverse torque shoulder enhances your load-bearing connection capabilities. • Achieve seamless wall alignment between pipe body and coupling. PERFORMANCE • Achieve connection strength on par with pipe body strength with our standard coupling. • Rely on the low angle taper to taper interference seal, reinforced by a reverse angle torque shoulder, for exceptional sealing reliability. • Reverse torque shoulder design offers high resistance to compression, bending, and over-torque stresses. • The inner flat design minimizes turbulence in gas and liquid flow, optimizing energy consumption. • Anti-galling design allows for numerous makeup and breakout cycles, ensuring durability.
PREMIUM CONNECTION/ RTV-200P
STRUCTURE
• Discover the strength of our innovative coupling design: Critical cross-sections surpass those of the pipe body, enhancing overall durability.
• Benefit from a modified hook thread profile with a -4° reverse angle on the load flank and a 10° angle on the lead flank, delivering outstanding tension strength and enhanced compression resistance. Sizes range from 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, to 8 5/8" and up with 4 TPI. • Our patented taper metal-to-metal seal system guarantees exceptional, gas-tight sealing under extreme conditions, such as bending and temperature fluctuations. • The reverse angle torque shoulder offers precise torque stopping, ensuring power-tight makeup precision and minimizing hoop stresses.
PERFORMANCE• Our coupling matches the pipe body's strength, ensuring robust connections. • Enjoy enhanced seal properties with a low angle taper to taper interference seal, strengthened by a reverse angle torque shoulder, ensuring exceptional reliability. • The hook thread and reverse torque shoulder design offer high resistance to compression, bending, and over-torque loads. • Our inner flat design significantly reduces turbulence, boosting energy efficiency. • The anti-galling feature supports multiple makeup and breakout cycles, ensuring long-lasting use.
