P-Quip Solution: Redefining Efficiency and Safety Through Excellence in Engineering

Core technology: automatic packing excitation with built-in cylinder

The P-Quip system's core innovation lies in its built-in cylinder. This design utilizes standard compressed air (100-150 psi) readily available to drilling crews as its power source.

operational principle ：

Installation: The flushing tube assembly is screwed into the threaded interface of the top drive spindle and goose neck tube.

Roots motivation: Connect the compressed air line to the specified "A" interface of the system. The air pressure drives the built-in piston and applies a strong, uniform and constant axial pressure on the root group to fully "motivate" (energize) it, so that it tightly adheres to the outer wall of the flushing tube and the inner wall of the root box to form a reliable dynamic seal.

Replacement: Release the air pressure, the built-in piston is reset under the action of the internal spring, relieve the pressure on the packing, at this time can easily replace the packing or the whole flushing tube.

Extreme efficiency and safety

Minute replacement: The entire flushing pipe and packing replacement process can be completed in a few minutes, which is an exponential improvement over traditional methods .

Essential safety design:

Hamless operation: eliminates all safety risks associated with hammering.

No brute force: no longer rely on the physical strength of the operator, reducing the risk of work-related injury caused by excessive force.

Humanized design: the system is equipped with special handling handle, which is convenient for personnel to operate and transport safely and stably.

Site suitability and certification

The P-Quip flushing system is designed for harsh well site environments with high applicability and reliability.

Complete drilling platform can be maintained: all maintenance work of the system can be completed on the drilling platform, without returning to the factory for maintenance, and the operation instructions are clearly marked on the product body.

Extensive compatibility: Provides a variety of specifications for NOV Varco, Hydralift and other mainstream top drive models, such as the common 6 1/4 inch x 3 TPI left-hand threaded interface rated up to 7500 PSI.

Authoritative certification: The system has been certified by authoritative institutions such as DNV, ensuring that its design, manufacturing and performance meet the highest industry standards.
