Product Description

VARCO top drive back-up tong assembly (Part No.: 30157287)
Model: CLAMP, CYLINDER, ASSY, PH75
This product is the core hydraulic component of the VARCO top drive system, designed for the top drive device of oil drilling rigs, and is used to efficiently complete the pipe string buckling operation. It is made of high-strength alloy steel, integrated with hydraulic cylinder and clamping mechanism, adapted to the PH75 top drive interface, and has the following technical characteristics:

High-performance clamping

Maximum clamping force of 75 tons, adapted to API standard drill pipe and casing

Bidirectional hydraulic drive, response time <0.5 seconds

Reliability design

Chrome-plated piston rod and wear-resistant seal combination, life of more than 500,000 cycles

Splash-proof structure complies with API 8C certification

Intelligent compatibility

Built-in pressure sensor interface, can be connected to the top drive control system

Modular design supports rapid replacement, maintenance hours reduced by 40%

Typical application scenarios include high-pressure conditions such as deep well drilling and shale gas development. The assembly has passed ISO 9001 quality system certification and provides a 12-month warranty service.
Key features include:
Connection Design: The upper end integrates with the top drive spindle via flanges or quick-connect couplings, while the lower end attaches to static mud standpipes or high-pressure hoses.
Fluid Dynamics: Optimized internal flow channels minimize turbulence and pressure loss, maintaining hydraulic efficiency during drilling.
Sealing and Safety: Integrated high-pressure sealing systems (e.g., mechanical seals or rotating control heads) prevent fluid leakage, complemented by pressure relief valves and monitoring interfaces for real-time safety management.
In drilling terminology, this component is referred to as a "gooseneck" or "S pipe". Its reliability directly impacts operational safety and drilling efficiency in demanding environments such as deep wells, directional wells, and high-temperature applications
