PREMIUM CONNECTION/ RTN-14AM STRUCTURE • Featuring a coupling connection type, our design achieves connection strength equal to or exceeding the pipe body. • The thread is an improved buttress type, enhancing connection efficiency and easing processing. 2 3/8"-2 7/8" 8 TPI, 3 1/2"-4 1/2" 6 TPI, 5" and over 5 TPI • The main seal employs a taper to taper seal structure with a negative angle torque shoulder for superior sealing ability. • The reverse torque shoulder enhances the connection's capability to bear combined loads. • Aligning the inner walls of the pipe body and coupling ensures seamless performance. PERFORMANCE • Our standard coupling connection achieves strength on par with the pipe body. • Seal efficiency: A low-angle taper-to-taper interference seal, bolstered by a reverse angle torque shoulder, ensures high seal reliability. • The reverse torque shoulder grants higher resistance to compression, bending, and over-torque. • An inner flat design minimizes gas and liquid turbulence, reducing energy loss. • Anti-galling features permit multiple makeups and breakouts. PREMIUM CONNECTION/ RTV-200P STRUCTURE • Our coupling design ensures critical cross-section dimensions exceed those of the pipe body. • Modified hook thread profile with a -4° reverse angle on the load flank and a 10° angle on the lead flank offers superior tensile strength and enhanced compression resistance. 2 3/8"-2 7/8" 8 TPI, 3 1/2"-4 1/2" 6 TPI, 5"-7 3/4" 5 TPI, 8 5/8" up 4 TPI • A patented taper metal-to-metal seal system provides exceptional gas-tight sealing, even under severe combined loads such as bending and temperature stress. • A reverse angle torque shoulder delivers a definitive torque stop for precise, power-tight makeup, minimizing hoop stress in the connection. PERFORMANCE• Our connection strength, with a standard coupling, rivals that of the pipe body. • Seal properties: The low-angle taper to taper interference seal, reinforced by a reverse angle torque shoulder, ensures high seal reliability. • Equipped with hook thread and a reverse torque shoulder, the joint offers outstanding resistance to compression, bending, and over-torque stresses. • An inner flat design reduces turbulence of gas and liquid flow, thereby minimizing energy loss. • The anti-galling design allows for multiple makeups and breakouts, promoting long-term usage.
