Pipe Base Screen The Perfect Combination of Strength and Material Excellence for Optimal Filtration Performance

Pipe-Base Screen Overview

The pipe-base screen integrates two critical components: a continuous slot wedge wire screen for hydraulic efficiency and a structurally robust base pipe, forming a dual-layer design often termed a "double-layer screen."

Base Pipe Specifications

Two primary base pipe configurations are utilized:

1. Perforated Pipe: Precision-drilled openings

2. Slotted Pipe: Strategically milled slots

All apertures undergo rigorous visual inspection and deburring to ensure optimal fluid dynamics. Manufacturing options include:

- Stainless steel alloys

- API 5CT-compliant carbon steel casing

Assembly & Applications

Through welded integration of screen and pipe, this system creates a robust and dependable assembly specifically engineered for:

- Deep vertical well completions

- Extended horizontal remediation operations

- High-collapse resistance scenarios

- Applications requiring longitudinal stress management

Industry Relevance

As an essential downhole component, pipe-base screens serve critical functions across:

- Hydrocarbon extraction systems

- Water well infrastructure

- Geothermal energy installations

The design prioritizes structural integrity while maintaining filtration performance, particularly where mechanical stresses exceed standard screen capabilities.

Material Excellence

• Engineered with high-performance alloys (316L/304 stainless steel or API 5CT carbon steel)

• ASTM-compliant manufacturing ensures:

- Superior pitting resistance (PREN ≥35)

- 120-150 ksi yield strength range

- Temperature resilience (-50°C to 450°C)

Precision Engineering

• Composite structure combines:

- Laser-perforated carrier pipe (5-20% open area)

- Helically wound filtration layer (0.1-3mm slot precision)

• Dual-stage quality control:

1. Eddy current testing for dimensional accuracy

2. Hydrostatic pressure validation (up to 15,000 psi)

Advanced Filtration Dynamics

• Gradient density design achieves:

- 98.7% particulate retention (≥50μm particles)

- Turbulence-reducing flow channels

- <2 psi differential pressure at 10 bbl/min

• Sand control efficiency:

- API RP 58 compliant sand retention

- 0.02 lb/ft³ maximum solids production

Operational Optimization

• Quick-connect coupling system reduces:

- Deployment time by 40% vs conventional screens

- Workover intervention frequency

• H2S/CO2 resistant surface treatment (Optional HVOF coating)
