Description

4140(42CrMo/42CrMo4) Grade Drilling Pipe – High-Strength Solution for Demanding Oilfield Wells​​

​Engineered for high-pressure, high-load drilling environments​​, 4140 grade drilling pipe delivers ​​exceptional strength, superior wear resistance, and reliable performance​​ for the toughest oilfield applications.

​​Key Advantages​​

1. ​​Ultimate Strength​​ – Tensile strength ≥950 MPa, yield strength ≥850 MPa for ​​deep wells and high-pressure reservoirs​​ (far exceeding standard grades).

2. ​​Premium Hardness (28–33 HRC)​​ – Exceptional resistance to ​​abrasion and wear​​ from drill cuttings and hard formations, extending service life.

3. ​​Quenched & Tempered (QT) Process​​ – Delivers ​​balanced strength and toughness​​, preventing brittle failure under extreme loads.

4. ​​High-Cost Performance​​ – Chromium-molybdenum (Cr-Mo) alloying provides ​​superior fatigue resistance and high-temperature stability​​ vs. standard carbon steels.

5. ​​Proven in Harsh Conditions​​ – Trusted for ​​ultra-deep wells, HPHT wells, and abrasive formations​​ where ordinary pipes fail.

​​Ideal for:​​ Deep drilling, high-pressure reservoirs, hard rock formations, and heavy-duty operations.

​​Upgrade from 4130/1541 when extreme strength and wear resistance are required.​

Applications include fore poling (advance support), mine blasting, water well drilling, geothermal well drilling, and coal/nonferrous metal mining.​​
