WRG (Weatherock Groups) provides premium connections and optimal performance in order to serve in the tough application surroundings. Moreover, this service is being widely used by its customers in South-East, Africa and South America. This Premium Connection is very beneficial for the end-user as it can greatly improve the usage, save cost and increase the life span. Lastly, it is having 5 further categories: TP-CQ | 2-3/8″~13-5/8″, TP-G2 | 2-3/8″~20″, TP-QR | 13-3/8″~20″, PT-Flush | 2-3/8″~11-3/4″, PT-H6 | 2-3/8″~4-1/2″. Premium Connection Casing Pipe Manufacturers and Premium Thread Casing Coupling Manufacturers come under WRG.
TP-CQ | 2-3/8″~13-5/8″ :
Few points about TP-CQ:
Structure Features:
- High-performance gas-tight premium connection for casting and tubing, ISO 13679 CALIV approved.
- Excellent gas seal-ability under combined load.
- Easy stabbing, No cross-threading.
- Superior Anti-galling performance.
- Easy repairing.
- Suitable for low alloy and carbon steel pipe.
Modified Buttress Thread:
- Taper=1:16.
- TBG: 2-3/8″~2-7/8″: 8T.P.I. 3-1/2″~4-1/2″: 6T.P.I.
- CSG: Sin~13-5/8:5T.P.I.
- Meta-Metal Seal.
- Seal Taper: TBG: 1:1.732 CSG: 1.10,1.6,1.3
- Reverse angle torque shoulder
Threaded Connection:
The thread crests minimize thread galling with the clearance at the top and avoid the tapping of the compound inside the threads. It improves and gives buttress thread with a taper of 1:16.
TP-G2 | 2-3/8″~20″:
Few points about TP-G2:
Structure Features:
- Gas-Tight premium connection for the deep, high deviated and horizontal well, IOS 13679 CALIV approved.
- Excellent resistance to bending, compression, and torque.
- Superior anti-galling performance.
- Reliable gas-tight sealing under any kind of combined loads
- Especially suitable for highly deviated and long horizontal wells.
- Suitable for high alloy and carbon steel pipes.
Hooked Thread:
- TBG: 2-3/8″~2-7/8″:8T.P.I.
- 3-1/2″~4-1/2″:6T.P.I.
- CSG: 5″~8-5/8″: 5T.P.I.
- 9-5/8″~20″: 4T.P.I.
Threaded Connection:
The 4* reverse angle on the load flank which provides the connection with superior tensile strength and increases its resistance to compression with a modified hook thread profile.
TP-QR | 13-3/8″~20″:
Few points about TP-QR:
Structure Features:
- 3T.P.I. coarse-thread enable fast make-up without cross-thread.
- Torque shoulder provides accurate power-tight make-up.
- Internal flush.
Threaded Connection:
High connection strength, fast and easy running without cross-threading through the coarse thread form with a taper of 1:12 and a lead of 3.T.P.I.
PT-Flush | 2-3/8″~11-3/4″:
The structure features of PT-Flush:
Structure Features:
- No Coupling and thread directly machined in the pipe, The internal/external wall of the connection flush with pipe body.
- Hook Thread. The thread is hook type, loading surface angle-3*, leading surface 25*, the thread pitch is 6TPL, and the thread taper depends on the different all thicknesses (Taper 1:1.6 or 1:10).
- Multiple seal system.
- Main seals adopt taper to taper seal structure, along with external and internal shoulder seal as the auxiliary.
- External torque shoulder is designed with -15* reverse angle, the internal shoulder is a rectangle shoulder, both shoulders withstand the torque at the same time.
PT-H6 | 2-3/8″~4-1/2″:
The structure features of PT-H6:
Structure Feature:
- The external and internal thread is machined directly in the pipe without couplings.
- Joint is used internal and external upset.
- PT-H6 used a cylindrical thread form, the load flame angle is 75*, and the stab flank angle is 20*. Thread pitch is 6T.P.I.
- There is no radial interference between the inner and outer thread.
- Taper metal to metal internal pressure seal is rated at 100% of the pipe body and the 100% external pressure seal is created at the torque shoulder.
