Explore our PREMIUM CONNECTION / RTN-14AM for unparalleled performance.
STRUCTURE • Engineered with a coupling connection type, the connection strength equals or surpasses that of the pipe body. • Features an improved buttress thread offering high efficiency and ease of processing. Sizes include 2 3/8"-2 7/8" 8 TPI, 3 1/2"-4 1/2" 6 TPI, 5" and over 5 TPI. • Utilizes a taper to taper seal structure with a negative angle torque shoulder to enhance sealing capability. • The reverse torque shoulder increases the combined load-bearing capacity. • Ensures inner wall alignment between the pipe body and coupling. PERFORMANCE • Connection strength achieves parity with the pipe body when using standard coupling. • Seal property enhanced by a low-angle taper interference seal and reverse angle torque shoulder, delivering high seal reliability. • The reverse torque shoulder equips the joint to handle compressive, bending, and over-torque loads efficiently. • Designed with an inner flat structure to minimize gas and liquid turbulence, reducing energy loss. • Incorporates an anti-galling design, allowing for multiple makeups and breakouts.

Experience the excellence of our PREMIUM CONNECTION / RTV-200P.
STRUCTURE
• Innovative coupling design: Critical cross sections surpass those of the pipe body, enhancing durability.
• Features a modified hook thread profile with a -4° reverse angle on the load flank and a 10° angle on the lead flank, offering superior tension strength and enhanced compression resistance. Sizes include 2 3/8"-2 7/8" 8 TPI, 3 1/2"-4 1/2" 6 TPI, 5"-7 3/4" 5 TPI, and 8 5/8" up 4 TPI. • The patented taper metal-to-metal seal system guarantees excellent gas-tight sealing, even under severe load conditions such as bending and temperature fluctuations. • The reverse angle torque shoulder provides a precise torque stop, allowing for power-tight makeup with minimal hoop stress.
PERFORMANCE• Connection strength meets the strength of the pipe body when utilizing standard coupling. • Seal property is enhanced with a low-angle taper interference seal and reverse angle torque shoulder, ensuring high seal reliability. • The hook thread and reverse torque shoulder empower the joint to resist compression, bending, and over-torque loads effectively. • Designed to minimize gas and liquid turbulence, the inner flat design reduces energy loss. • Anti-galling feature allows for multiple makeups and breakouts, enhancing longevity and reliability.
