Product Overview

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
  • Ultimate Strength - Tensile strength ≥950 MPa, yield strength ≥850 MPa for deep wells and high-pressure reservoirs (far exceeding standard grades)
  • Premium Hardness (28-33 HRC) - Exceptional resistance to abrasion and wear from drill cuttings and hard formations, extending service life
  • Quenched & Tempered (QT) Process - Delivers balanced strength and toughness, preventing brittle failure under extreme loads
  • High-Cost Performance - Chromium-molybdenum (Cr-Mo) alloying provides superior fatigue resistance and high-temperature stability vs. standard carbon steels
  • Proven in Harsh Conditions - Trusted for ultra-deep wells, HPHT wells, and abrasive formations where ordinary pipes fail
Applications

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.
