Description of Premium Connection TP-FJ

OD and ID are 100% Flush

Maximum clearance

Designed for medium or heavy wall casing

Threaded Connection

Buttress threads form with a taper of 1:16 and a lead of 5TPI, which can be measured by API gauge, more applicable for medium or heavy wall pipes. Pipe to pipe is connected without coupling.

Metal-to-Metal Seal

Metal-to-Metal seal surface provides enough contact length and contact pressure. The Metal-to-Metal seal system offers excellent gas-tight sealing, even under the most severe combined loads. The seal integrity remains constant after repeated make-ups and break-outs. Optimized thread geometry minimizes the risk of galling, even when thread compounds are poorly applied.

Reverse Angle Torque Shoulder of TP-FJ

A reverse angle torque shoulder provides accurate power-tight make-up, which also enhances Metal-to-Metal sealing.

TP-FJ Internal Profile

The OD and ID are 100% flush, which gives the maximum clearance.

Coupling Design

Joint efficiency is more than 100% and the coupling critical section is greater than the pipe body section. Because the coupling covers the vanishing threads therefore the connection tensile efficiency is maximized.

Connection Low-Stress Design

The lower stress design makes the connections reliable in corrosive conditions.
