Description

30CrMo/34CrMo4 4130 Grade Drilling Pipe – Balanced Strength & Weldability for Versatile Oilfield Applications​​

​​ Engineered for conventional to mid-depth oilfield wells​​, 4130 grade drilling pipe delivers ​​optimal strength, weldability, and cost efficiency​​ – making it the reliable choice for diverse drilling operations.

​​Key Features & Benefits​​

1. ​​Balanced High Strength​​ - ​Tensile strength ≥813 MPa, Yield strength ≥690 MPa​​ – Provides ​​reliable load-bearing capacity​​ for medium-depth wells (≤3,000m) and standard pressure conditions (≤35 MPa), ensuring structural integrity during drilling.

2. ​​Superior Weldability​​ - ​​Low carbon content with chromium-molybdenum (Cr-Mo) alloying​​ – Enables ​​easy field welding​​ (minimal preheat/post-weld heat treatment required) while maintaining toughness, ideal for on-site casing connections or repairs.

3. ​​Controlled Toughness & Ductility​​ - ​​Elongation ≥15%​​ – Absorbs ​​dynamic loads​​ (e.g., bit vibration, pressure fluctuations) and resists brittle fracture, ensuring operational safety in varied well conditions.

4. ​​Cost-Effective Performance​​ - ​​Moderate alloy cost (Cr-Mo optimized)​​ – Delivers ​​premium-grade strength at a lower price point than 4140​​, balancing performance and budget for conventional to mid-range wells.

5. ​​Proven Reliability​​ - Widely used in ​​onshore/offshore conventional wells, water wells, and geothermal projects​​ – Backed by decades of field performance in stable to moderately complex formations.

​​Why 4130?​​

1. ​​Versatile Mid-Range Performance​​ – Ideal for ​​wells ≤3,000m with standard pressure/temperature​​ , avoiding over-engineering of high-end grades (e.g., 4140).

2. ​​Weld-Friendly & Easy to Maintain​​ – Simplifies ​​field operations​​ (e.g., welding, threading) without sacrificing strength, reducing downtime and costs.

3. ​​Better Than Carbon Steel​​ – Outperforms basic carbon steels (e.g., 1541) in ​​strength, fatigue resistance, and corrosion resistance​​ (mild environments).

Suitable for mine blasting, water well drilling, geothermal well drilling, fore poling, and mining of coal and nonferrous metals.​
