API RP 13C Compliant Screens (62735FATX Series) and VSM 300 Screens

Introduction

In oilfield drilling operations, shaker screens are critical components that directly determine solids control efficiency, drilling fluid purity, and the service life of downstream equipment. Our product line includes API RP 13C Compliant Screens (model numbers: 62735FATX080, 62735FATX100, 62735FATX120, 62735FATX140, 62735FATX170, 62735FATX200, 62735FATX230, 62735FATX270, 62735FATX325) and VSM 300 Series Screens—including VSM 300 Primary RHD (62735FOTD089 to 62735FOTD330), VSM 300 Primary XF (62735FXTD070 to 62735FXTD425), and VSM 300 Scalping MG (63727FMSD010 to 63727FMSD100). These screens are engineered to address the core pain points of oilfield operators: frequent screen replacement, poor filtration accuracy, short service life in harsh downhole conditions, and non-compliance with industry standards that lead to operational delays and increased costs.

Designed for specific drilling equipment and user needs, our screens are fully compliant with API RP 13C, the global standard for shaker screen physical testing and labeling, which will soon be adopted as ISO 13501 internationally. The API RP 13C Compliant 62735FATX Series is tailored for general solids control systems requiring strict adherence to industry certification, while the VSM 300 Series is exclusively matched to VSM 300 drilling shakers—with RHD models for primary solids separation, XF models for high-efficiency fine filtration, and Scalping MG models for coarse solids removal in scalping applications. Our core goal is to provide reliable, long-lasting screen solutions that reduce downtime, lower maintenance costs, and ensure consistent drilling performance for oilfield operators, drilling contractors, and maintenance teams worldwide.

Product Overview

API RP 13C Compliant Screens (62735FATX Series)

The 62735FATX Series is purpose-built to meet the rigorous requirements of API RP 13C, which mandates standardized testing and labeling for shaker screens to ensure uniform solids size removal and cross-comparability of screen designs. Each screen in this series undergoes strict D100 cut point testing and conductance measurement (rated at 0.8-1.2 kilo darcies per millimeter) to guarantee consistent filtration performance. Unlike generic screens that often fail to meet API standards, our 62735FATX Series provides test data upon request, as required by API RP 13C, giving operators full confidence in compliance and performance.

VSM 300 Series Screens

The VSM 300 Series is custom-engineered for VSM 300 drilling shakers, with three specialized sub-series to address distinct solids control needs:

• VSM 300 Primary RHD Screens (62735FOTD Series): Designed for primary solids separation, these screens handle high-volume drilling fluid flow and remove medium to large solids, reducing the workload on downstream filtration equipment.

• VSM 300 Primary XF Screens (62735FXTD Series): Optimized for fine filtration, these screens feature a tighter mesh design to capture small solids, ensuring drilling fluid meets the purity requirements for continued use.

• VSM 300 Scalping MG Screens (63727FMSD Series): Built for scalping applications, these screens efficiently remove coarse solids early in the drilling process, preventing damage to shaker components and improving overall system efficiency.

Function & Structural Features

Core Functions

All our screens serve three critical functions: solids control (removing unwanted particles from drilling fluid), drilling fluid purification (ensuring fluid reusability and reducing waste), and equipment protection (preventing abrasive solids from damaging pumps, valves, and other downhole tools). The 62735FATX Series focuses on API-compliant precision filtration, while the VSM 300 sub-series target specific stages of solids separation—from coarse scalping to fine polishing.

Structural Features

Our screens are constructed with durability and performance in mind, addressing common failure points of generic screens:

• Frame Material: High-strength composite frame (for VSM 300 Series) and 316L stainless steel frame (for 62735FATX Series) to resist corrosion, impact, and warping in harsh drilling environments. The composite frame reduces weight by 12 pounds per screen compared to steel frames, easing installation while maintaining structural integrity.

• Mesh Design: Multilayer woven stainless steel mesh with a V-shaped flow channel (outer wide, inner narrow) for self-cleaning performance, reducing clogging and extending service life. The mesh is welded using resistance welding at every contact point to prevent detachment under high vibration.

• Sealing System: High-temperature resistant rubber gaskets (withstand up to 350°F) to prevent drilling fluid leakage, a common issue that leads to equipment damage and reduced filtration efficiency.

• Fit Precision: Each screen is precision-manufactured to match the exact dimensions of API-compliant solids control systems and VSM 300 shakers, ensuring a seamless fit that eliminates vibration-induced wear. Our screens have a dimensional tolerance of ±0.005 inches, compared to the industry average of ±0.01 inches.

Applicable Working Conditions

Our screens are engineered to perform reliably in the most demanding oilfield conditions, addressing the pain points of extreme temperatures, high pressure, and abrasive fluids:

• Temperature Range: -40°F to 350°F, suitable for both onshore and offshore drilling in cold northern fields and high-temperature desert regions.

• Pressure Resistance: Up to 150 psi, handling high-flow drilling fluid without screen deformation or failure.

• Fluid Compatibility: Compatible with both oil-based and water-based drilling fluids, as well as corrosive fluids containing saltwater or hydrogen sulfide.

• Formation Adaptability: Effective for loose sand formations, shale formations, and high-solids drilling environments, with the 62735FATX Series handling D50 cut points from 80 to 325 microns and the VSM 300 Series covering 10 to 425 microns to match different formation particle sizes.

Maintenance & Engineer Practical Advice

Proper maintenance is key to maximizing screen service life and performance. Below are practical tips from our senior field engineers, designed to avoid common mistakes and reduce downtime:

• Daily Inspection: Check screens for mesh damage, gasket leaks, and clogging before each shift. Use a soft brush to remove surface solids—avoid using high-pressure water, which can damage the mesh.

• Replacement Timing: Replace screens when fluid throughput drops by 30% or when mesh damage exceeds 2 square inches—delaying replacement can lead to fluid contamination and equipment damage. Our screens have an average service life of 72-96 hours under normal load, 30 hours longer than industry averages.

• Storage: Store screens in a dry, clean environment, away from direct sunlight and corrosive materials. Avoid stacking more than 5 screens to prevent frame warping.

• Installation: Ensure screens are properly tensioned—over-tensioning can crack the frame, while under-tensioning causes vibration and mesh damage. Follow the shaker manufacturer’s tensioning guidelines, and use a torque wrench to ensure consistent tension (35-40 ft-lbs).

• Risk Avoidance Tips: Never mix screen models—using a non-VSM 300 screen on a VSM 300 shaker will cause poor fit and premature failure. Also, avoid using screens that are not API RP 13C compliant in regulated operations, as this can lead to fines and project delays.
