High-Quality API Casing and Tubing for Oil & Gas Industry

 

PREMIUM CONNECTION/ RTN-14AM
STRUCTURE • Experience a coupling connection type engineered to match or even surpass the strength of the pipe body. • Enhanced buttress thread ensures superior connecting efficiency and effortless processing. Available 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. • The taper-to-taper seal structure, featuring a negative angle torque shoulder, significantly boosts sealing capabilities. • Cutting-edge reverse torque shoulder enhances the load-bearing capacity of the connection. • Seamless wall alignment between the pipe body and coupling. PERFORMANCE • Achieve connection strength that rivals the pipe body strength with standard coupling. • A low-angle taper to taper interference seal, fortified by a reverse angle torque shoulder, provides exceptional 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 for multiple makeup and breakout cycles, enhancing operational durability.

PREMIUM CONNECTION/ RTV-200P
STRUCTURE
• Our innovative coupling design features critical cross-sections that surpass those of the pipe body, delivering unparalleled strength and endurance.
• Features a modified hook thread profile with a -4° reverse angle on the load flank and a 10° angle on the lead flank, providing 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. • Our patented taper metal-to-metal seal system guarantees exceptional gas-tight sealing under severe conditions, including bending and temperature fluctuations. • The reverse angle torque shoulder ensures precise torque stopping, allowing for accurate power-tight makeup and minimizing hoop stresses.
PERFORMANCE• Achieve connection strength that mirrors the robustness of the pipe body with our standard coupling. • Seal properties are enhanced by a low angle taper-to-taper interference seal, reinforced by a reverse angle torque shoulder, ensuring superior seal reliability. • The hook thread and reverse torque shoulder design provide high resistance to compression, bending, and over-torque loads. • Our 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 performance and usability.
