Packing & Delivery

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

FAQ

1-Package and transportation
According to the different characteristics of goods and customer needs, we provide a variety of packaging methods, can also be packaged according to customer requirements, packaging types include wooden boxes, iron shelves, environmental protection paper boxes, containers, etc., to ensure the safety and integrity of goods in the process of transportation:
Wooden case packaging: suitable for heavy or large volume goods, such as machinery and equipment, large parts and so on. Wooden pallet packaging has high load-bearing capacity and stability, can effectively prevent the goods from moving or damaged in the process of transportation
Paper box packaging: suitable for lightweight, fragile or regular small goods, such as electronic products, daily necessities, etc. Environmental paper box is not only low cost, but also has good environmental performance
Wood pallet packaging: The goods are fixed on the wooden pallet and reinforced with bolts or nails to ensure that the goods are closely combined with the wooden pallet. For heavy goods, additional support structures are added to prevent the goods from tilting during transportation
Container packaging: suitable for the transportation of large quantities of goods, can effectively use space, reduce transportation costs. The interior of the container can be customized according to the characteristics of the goods to ensure the safety of the goods
2-Marks and labels:
The name, specification, quantity, destination, transportation requirements and other information of the goods shall be clearly marked on the packaging surface to ensure identification and convenient operation during transportation
For special goods (such as fragile goods, dangerous goods), post a prominent warning label to remind the transport personnel to pay attention to the operation.
