DL Rapid-Fit Hammerless Discharge Strainer

The P-Quip system tackles the core challenges of NPT (Non-Production Time), with its most notable value being the reduction of filter replacement or cleaning time to under 5 minutes. This represents a revolutionary leap forward compared to traditional methods, enabling customers to easily calculate their return on investment (ROI). For instance, if conventional filter replacement takes 30 minutes and the drilling rig's NPT cost is $6,000 per hour, the indirect cost per maintenance session would be $3,000. With the P-Quip system, this cost drops below $500, delivering immediate savings with each maintenance. In practice, the payback period for P-Quip systems typically falls under six months.

New HSE standards: End the "hammer era"

In traditional maintenance procedures, using a sledgehammer and "forceps" to strike and tighten threaded fasteners remains a common yet extremely hazardous practice. This brute-force approach is the primary cause of work-related injuries (LTI), including finger crush injuries, muscle strain, and heavy object impact injuries. The P-Quip system fundamentally eliminates the need for sledgehammers through its intrinsically safe design philosophy. The entire operation requires only standard pneumatic or manual hydraulic pumps, allowing operators to stay away from hazardous areas and significantly reducing workplace injury risks.

The lowest total cost of ownership (TCO) in the industry

The core pillars of its low TCO include:

Excellent durability: Top manufacturing processes (such as forging and heat treatment) are used to ensure a field-validated service life of up to 20 years.

Very low maintenance costs: faster and safer maintenance cycles significantly reduce labor costs and related costs associated with NPT.

Protection of downstream assets: The core function of the filter is to protect the pump internals and expensive measurement with a borehole logging tool (MWD/LWD) from debris damage, thereby avoiding more expensive equipment failure.

Manufacturing: The scientific basis of durability

The absolute advantage of forging process: compared with the traditional casting process, forging process has the essential superiority

Cutting-edge material science: The core structural components of the P-Quip system are forged from AISI 4130 low-alloy steel. This chromium-molybdenum steel ("Chromoly") is the go-to material for high-stress components in the oil and gas industry-like valve bodies and pump parts-thanks to its exceptional strength, toughness, fatigue resistance, and weldability.

Advanced heat treatment processes: After forging, the workpiece undergoes specialized heat treatments including quenching, tempering, and surface hardening. These procedures create an extremely hard wear-resistant layer on the component's surface while maintaining core toughness. This dual-action approach achieves "enhanced grain flow and deeper hardened layers in critical areas," significantly improving the part's crack resistance.

Robust Stainless Steel Filter Element: The filter tube, the core component of the filter system, is constructed from durable stainless steel. This ensures exceptional wear and corrosion resistance in abrasive drilling fluids with complex chemical compositions, guaranteeing both filtration efficiency and extended service life. For similar applications, stainless steel grades such as 304 or 316 are typically selected.

Patent rapid change mechanism: the core technology of the system

Working principle: The core of the P-Quip system is its patented quick-change mechanism. During normal operation, a powerful spring mechanism provides a constant and large clamping force on the filter cover, ensuring a firm seal under high pressure.

Operation Procedure: When maintenance is required, the operator simply connects a standard pneumatic or manual hydraulic pump to port 1 on the housing. Upon activation of the hydraulic system, fluid pressure acts on the internal piston to overcome spring resistance, releasing the clamping force on the filter cover. This enables easy removal of the cover plate for filter cleaning or replacement. After maintenance, releasing the hydraulic pressure automatically resets the spring mechanism, reapplying reliable clamping force to the cover plate.

Automatic Clamping Technology: This groundbreaking innovation distinguishes itself from conventional thread fixation methods. Traditional thread fasteners rely entirely on operators' experience and torque application, making them prone to either over-tightening or under-tightening. In contrast, the P-Quip system employs precisely calculated spring forces through advanced algorithms, achieving "automatic clamping" that virtually eliminates the risk of misalignment. The high-frequency vibrations generated during mud pump operation are the primary cause of loosening and failure in traditional thread fasteners. The spring mechanism in P-Quip provides active, continuous clamping force that effectively counteracts vibration effects, ensuring long-lasting seal stability and completely resolving the chronic issue of "loosening" in traditional thread fixtures under vibrating conditions.
