High-Flow Slotted Production Liner Tubing

High-Flow Slotted Production Liner Tubing  

Manufacturer: Dongying Mingde Petroleum Technology Co., Ltd.  

Engineered for Maximum Productivity  

Dongying Mingde's high-flow slotted production liner tubing delivers superior hydrocarbon and water recovery through scientifically optimized designs. Featuring 1-6% precisely controlled open area, our CFD-modeled slot patterns achieve higher flow rates than industry standards while maintaining absolute sand control. Ideal for heavy oil, dewatering operations, and high-volume aquifers where efficiency drives profitability.  

The Gold Standard for Water Wells

As Dongying Mingde's flagship optimal water well screen liner, this solution combines precision engineering:  

- Aquifer-Specific Slotting: 0.008"-0.060" widths tailored to formation gradation  

- Biofouling Defense: Electropolished 304/316L stainless steel (Ra<0.8μm)  

- Zero-Corrosion Guarantee: 30+ year service life in mineral-heavy groundwater  

- Open Area Mastery: 1-6% configurable for optimal flow/sand control balance  

Proven in municipal supply wells across Shandong Province and agricultural projects throughout the Yellow River Basin.  

Precision-Tailored Dimensions  

Dongying Mingde delivers perfectly sized tailored length OD/ID slotted liner with unmatched manufacturing accuracy:  

No wellbore deviation too challenging – we manufacture to your exact wellbore geometry.
