PREMIUM CONNECTION/ RTN-14AM

STRUCTURE • Our coupling connection type ensures connection strength equal to or greater than the pipe body. • Features improved buttress thread for high connecting efficiency and ease of processing. 2 3/8"-2 7/8" 8 TPI 3 1/2"-4 1/2" 6 TPI 5" and over 5 TPI • Main seal uses taper to taper seal structure with negative angle torque shoulder for superior seal ability. • Reverse torque shoulder enhances bearing capacity for combined load. • Inner walls of pipe and coupling are perfectly aligned. PERFORMANCE • Connection strength equal to pipe body with standard coupling. • Low angle taper to taper interference seal, further strengthened by reverse angle torque shoulder, ensures high seal reliability. • Joint resists compression, bending, and over-torque loads. • Inner flat design reduces turbulence, lowering energy loss. • Anti-galling design allows multiple makeups and breakouts.

PREMIUM CONNECTION/ RTV-200P

STRUCTURE

• Coupling design: Features critical cross sections larger than the pipe body for superior strength.

• Modified hook thread profile with -4° reverse angle on load flank and 10° angle on lead flank provides superb tension strength and 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 • Patented taper metal-to-metal seal system offers excellent gas-tight sealing under severe loads. • Reverse angle torque shoulder for precise power-tight makeup, minimizing hoop stresses.

PERFORMANCE• Connection strength with standard coupling reaches pipe body strength. • Seal property enhanced by low angle taper to taper interference seal and reverse angle torque shoulder, ensuring high seal reliability. • Hook thread and reverse torque shoulder allow joint to resist compression, bending, and over-torque loads. • Inner flat design lowers gas and liquid turbulence, reducing energy loss. • Anti-galling design permits multiple makeups and breakouts.
