PREMIUM CONNECTION/ RTN-14AM

STRUCTURE • Our coupling connection type ensures the connection strength meets or exceeds that of the pipe body for reliable performance. • Featuring an improved buttress thread for high efficiency, facilitating easy processing. Sizes: 2 3/8"-2 7/8" 8 TPI, 3 1/2"-4 1/2" 6 TPI, 5" and over 5 TPI. • The main seal boasts a taper to taper seal structure with a negative angle torque shoulder, enhancing sealing ability. • The reverse torque shoulder bolsters connection capacity to bear combined loads. • The inner wall of the pipe body aligns seamlessly with the coupling inner wall for optimal flow.

PREMIUM CONNECTION/ RTV-200P

STRUCTURE

• Ingenious coupling design: Featuring critical cross sections greater than those of the pipe body for enhanced structural integrity.

• Our innovative hook thread profile boasts a -4° reverse angle on the load flank, with a 10° angle on the lead flank, delivering superior tension strength and heightened compression resistance. Sizes: 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. • Our patented taper metal-to-metal seal system ensures outstanding gas-tight sealing, even under severe combined loads like bending and temperature variations. • The reverse angle torque shoulder offers a positive torque stop for precise power-tight makeup and reduces hoop stresses, optimizing connection.

PERFORMANCE• Exceptional connection strength: The connection with a standard coupling matches the pipe body's strength. • Superior sealing properties: Our low angle taper to taper interference seal, further enhanced by the reverse angle torque shoulder, ensures high seal reliability. • With a hook thread and reverse torque shoulder, the joint excels in resisting compression, bend, and over-torque loads. • The inner flat design minimizes gas and liquid turbulence, reducing energy loss. • Our anti-galling design permits multiple makeups and breakouts, ensuring long-lasting performance.
