30CrMnSiA Grade Drilling Pipe: Corrosion-Resistant, High-Strength &
Weldable Wellbore Solution
Engineered for medium-high pressure, weakly corrosive, and
dynamically loaded well conditions, the 30CrMnSiA-grade drilling
pipe combines chromium-manganese alloy reinforcement, superior
weldability, and balanced toughness to deliver reliable
performance in complex oilfield applications.
Core Advantages
1. High-Strength Corrosion Resistance - Tensile strength ≥850
MPa; chromium (0.80–1.10%) forms a passive oxide layer to resist
brine/weak acid fluids, outperforming standard carbon steels.
2. Lightweight Yet Tough - Lighter than 4140 steel, reducing tripping loads while maintaining high strength (comparable to 4130), ideal for deep well structural demands.
3. Worry-Free Weldability - Low carbon equivalent design enables low-preheat field welding, ensuring reliable wellbore connections and repairs.
4. Dynamic Adaptability - Elongation ≥14% absorbs vibrations/pressure pulses, minimizing crack risks and extending service life.
Why Choose 30CrMnSiA?
1. Beats 1541 – Superior corrosion resistance for water
injection wells, offshore wells, and moderately corrosive
environments.
2. Cost-Effective Balance – Lower alloy investment than 4140/4130, with performance matching premium grades.
3. 30CrMnSiA Grade – The ideal choice when your well demands strength, corrosion resistance, and weld-friendly performance.
Applications include fore poling (advance support), mine blasting, water well drilling, geothermal well drilling, and coal/nonferrous metal mining.
