Winsteel Group supplies Premium Connection TP-FJ. This special product manufactured by TPCO. We have built a long-term and reliable relationship with TPCO. It is the high-performance gas-tight premium connection. For casing and tubing ISO 13679 CAL IV approved.
API Buttress thread
Size Range of Premium Connection TP-FJ
Advantage of Premium Connection TP-FJ
- Firstly, Excellent gas seal-ability under combined load
- Secondly, Easy stabbing, No cross threading
- Thirdly, Superior Anti-galling performance
- Fouthly, Easy repairing
- Further, Suitable for low alloy & carbon steel pipe
Description of Premium Connection TP-FJ
- OD and ID are 100% Flush.
- Maximum clearance.
- Designed for medium or heavy wall casing.
Buttress threads form with a taper of 1:16. And a lead of 5TPI which can measure by API gauge. more applicable for medium or heavy wall pipes. But, pipe to pipe connected without coupling.
Metal-to-Metal seal surface provides enough contact length and contact pressure. Meanwhile, 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 poor applied.
Reverse Angle Torque Shoulder of TP-FJ
So, 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 max. clearance.
A kind of flush thread connection with pipe end upset. It can increase the ability of thread connection strength and resistance to bending. Two-step thread can improve the efficiency of field operation. Using tapered to tapered surface as the structural design og themain seal. Provide good gas sealing performance. the external torque shoulder can achieve precise control. Thickening of the inside and outside reverse torque shoulder can effectively prevent the plastic deformantion under high compressive load.
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 so the connection tensile efficiency.
Connection Low-Stress Design
Certainly, the lower stress design makes the connections reliable in corrosive conditions.
There are many types of premium connection mainly for good sealing performance. Resistant to high torque and damage repairing etc. We establish strategic partner with many famous mills. Such as Baosteel, TPCO, valin and so on who through the international certification .
In short, we can supply many kinds of application connections. Including threaded and coupled connection. Flush and semi-flush joint connection without coulple. For example TPCQ, BG-GJ, VAM series, Tenaris series, Hydrill series, JFE series, and their equivalent connections.
So, to provide service in tough application surroundings. Winsteel Group Limited supplies optimal performance and premium connections. So it used widely by our customers in South-East, South America, and Africa. That is to say our premium connections can great improve the usage span life and save costs for the end-user.
