PREMIUM CONNECTION/ RTN-14AM

STRUCTURE • Coupling connection type ensures strength that matches or exceeds the pipe body itself. • Enhanced buttress thread is designed for high-efficiency connection 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 features a taper to taper with a negative angle torque shoulder for improved sealing capability. • Reverse torque shoulder increases the connection's ability to bear combined load. • Alignment of the pipe body's inner wall with the coupling's inner wall. PERFORMANCE • Connection strength: With the standard coupling, it matches the pipe body strength. • Seal reliability: The low angle taper to taper interference seal, strengthened by the reverse angle torque shoulder, ensures high seal reliability. • The joint's design resists compression, bend, and over-torque loads effectively. • The inner flat design minimizes gas and liquid turbulence, reducing energy loss. • Anti-galling design permits multiple makeups and breakouts.

PREMIUM CONNECTION/ RTV-200P

STRUCTURE

• Innovative Coupling design: Critical cross sections are crafted to surpass those of the pipe body itself.

• Modified hook thread profile: Featuring a -4°reverse angle on the load flank and a 10°angle on the lead flank, this profile provides superior tension 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 4TPI • A patented taper metal-to-metal seal system ensures excellent gas-tight sealing, even under severe combined loads like bending and temperature variations. • Reverse angle torque shoulder acts as a positive torque stop, allowing for precise power-tight makeups and minimizing hoop stresses.

PERFORMANCE• The connection strength with standard coupling aligns with pipe body strength. • Seal property: The low angle taper to taper interference seal, complemented by the reverse angle torque shoulder, ensures exceptional seal reliability. • The hook thread and reverse torque shoulder design enhances resistance to compression, bend, and over-torque loads. • Inner flat design reduces turbulence of gas and liquid, optimizing energy efficiency. • Anti-galling design allows for repeated makeup and breakout cycles.
