YQ140-30W No Marking Hydraulic Power Tong for Workover

 While trip the coated tubing, glass fiber tubing, plastic tubing, VAM TOP, BGT1, FOX, 3SB, 13Cr and other anticorrosive tubing, tubing surface without damage is common challenge for  the world's petroleum equipment manufacturing, researchers adopted carbide coating, carbide sintering, diamond mesh cushion layer and other methods, the hardness of the material is higher than the pipe material, also the pipe surface corrosion layer damage, but the damage point, not easy to observe, the cumulative damage area is larger.After years of research, our researchers has solved this problem with soft gram steel, using high strength, high friction coefficient of elastic synthetic fiber, through high density weaving, all materials hardness is lower than HS80 (Shaw's hardness), hardness is lower than alloy aluminum.There is no clamp marks on the pipe body surface of 13Cr chromium pipe, coated pipe, FRP pipe and plastic pipe.

 Equipment features

1. According to the requirements of the production process, the backup tong can hold the body or the clamp.

2. No-marking dies are non-metallic material (composite material), with good elasticity, high toughness, impact resistance, high strength, wear resistance, and strong dual consistency, especially suitable for clamping tube with anti-corrosion coating, no marking on the body surface, really no damage holding, suitable for VAM TOP, BGT1, FOX, 3SB, 13Ca and other special pipe and ordinary buckle, ordinary material pipe, especially suitable for coating pipe.

3. Using automatic variable speed hydraulic power station, the automatic variable speed system realizes the automatic control of the stepless variable speed in the process of making up; high- speed making up and low-speed torque tighting, which can not only improve the working efficiency, but also comply with the API specifications, to ensure that the pipe with a shoulder buckle does not exceed the torque.

4. The tong head structure is open type, the pipe fittings can enter and exit fast and conveniently. The strength and stiffness of intergal tong head and are good.

5. The jaw plate of main tong is a swing-type roller climbing mechanism, convenient disassembly, reliable clamp and easy slope reduction; the backup tong is cylinder- pushing clamping mechanism, with simple structure and reliable clamping.

6. Adopt four-gear speed, wide speed adjustment range and large rated torque.

7. Brake belt braking mode, large braking torque, simple operation, easy to repair and replacement

8. Open large gear has a supporting structure to greatly increase its strength and stiffness

9. The body adopts high-strength steel plate with good overall strength.Jaw plate adopts forging material, with beautiful appearance and high strength;

10. The clamping force of no-marking tong is 50% more than that of ordinary tong.

11. The touching area between the clamping body and the pipe is increased by 200-fold over ordinary tong.

12. Since the touching area between clamping body and pipe is 300°circumference,  the pipe body will not deform even if clamping force increases by 50%.

13. The material friction coefficient of the pipe anticorrosion coating is different, the torque of making up also changes, and the cleaning degree of the pipe surface also affects make-up torque.

14. Equipped with torque control recorder, and the installation interface for laps and torque instrument to facilitate computer management.

15. 30000N·m.Maximum torque up to 30,000 N m.

16. The floating arm tong can accurately detects the buckle torque.

17. Sets the operation parameters, pipe body and hoop parameters by menu.

18. Display and control the buckle torque on the pipe, shoulder torque and shoulder turn number by figure line.

 NKY- C8ExTouch-screen explosion-proof torque control recorder

    NKY-C8Ex touch screen explosion-proof torque control recorder is used with hydraulic power tong to monitor the twisting torque of pipe joint, to ensure that the twist torque control within the API standard, to avoid the buckle or incincer damage caused by pipe joint tightening, and fully meet the strict standards and requirements when the pipe into the well.
   NKY-C8Ex touch screen explosion-proof torque control recorder is mainly composed of touch screen torque display recorder, power adapter, torque sensor, solenoid unloading valve and other parts. With simple structure and low failure rate, it is suitable for places with explosion-proof requirements.
