1. 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:
1. High-performance gas-tight premium connection for casting and tubing,
ISO 13679 CALIV approved.

2. 2. Excellent gas seal-ability under combined load.
3. Easy stabbing, No cross-threading.
4. Superior Anti-galling performance.
5. Easy repairing.
6. Suitable for low alloy and carbon steel pipe.
Modified Buttress Thread:
1. Taper=1:16.
2. TBG: 2-3/8"~2-7/8": 8T.P.I. 3-1/2"~4-1/2": 6T.P.I.
3. CSG: Sin~13-5/8:5T.P.I.
4. Meta-Metal Seal.
5. Seal Taper: TBG: 1:1.732 CSG: 1.10,1.6,1.3
6. 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:
1. Gas-Tight premium connection for the deep, high deviated and horizontal
well, IOS 13679 CALIV approved.
2. Excellent resistance to bending, compression, and torque.
3. Superior anti-galling performance.
4. Reliable gas-tight sealing under any kind of combined loads
5. Especially suitable for highly deviated and long horizontal wells.
6. Suitable for high alloy and carbon steel pipes.
Hooked Thread:
1. TBG: 2-3/8"~2-7/8":8T.P.I.
2. 3-1/2"~4-1/2":6T.P.I.
3. CSG: 5"~8-5/8": 5T.P.I.
4. 9-5/8"~20": 4T.P.I.
Threaded Connection:

3. 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:
1. 3T.P.I. coarse-thread enables fast make-up without cross-thread.
2. Torque shoulder provides accurate power-tight make-up.
3. 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:
1. No Coupling and thread directly machined in the pipe, The
internal/external wall of the connection flush with pipe body.
2. 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).
3. Multiple seal system.
4. Main seals adopt taper to taper seal structure, along with external and
internal shoulder seal as the auxiliary.
5. 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:

4. 1. The external and internal thread is machined directly in the pipe without
couplings.
2. Joint is used internal and external upset.
3. 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.
4. There is no radial interference between the inner and outer thread.
5. 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.
