Slotted Liner for Geothermal Wells and CO? sequestration wells Well Completion

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 H?S, CO?, 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.
