Premium Engineering for Demanding Well Environments
Our stainless steel slotted liner pipe is engineered to deliver unmatched durability and performance in the harshest downhole conditions. Manufactured from high-grade 304L/316L/duplex stainless steel, these liners provide superior structural integrity where conventional carbon steel fails. Ideal for corrosive reservoirs, steam injection wells, and high-salinity environments, they outperform competitors with 3-5× longer service life.
Unrivaled Corrosion Resistance
As a truly corrosion resistant well screen liner, this solution combats H₂S, CO₂, brine, and acidic fluids that degrade conventional screens. Key features include:
- Material Science: Chromium-nickel-molybdenum alloy matrix creates passive oxide barrier
- Protection: Resists pitting/crevice corrosion (ASTM G48 compliant)
- Longevity: 15+ year service life in sour gas wells (NACE MR0175 certified)
- Cost Savings: Eliminates workover costs from screen failure
Precision Slot Technology
Achieve perfect sand control with our precise slot width slotted liner, featuring laser-cut accuracy within ±0.002" (0.05mm)
Microscopic slot consistency prevents sand ingress while maximizing flow efficiency - critical for unconsolidated formations.
