Description

AISI 4340 Chromoly Alloy Oil Drilling Pipe , Seamless Steel Pipe for Nonferrous Metal Mining Projects

Description

This AISI 4340 chromoly alloy drilling pipe represents advanced seamless tubing engineered for the most demanding oil drilling and nonferrous mining operations. Manufactured from nickel-chromium-molybdenum alloy steel, it delivers exceptional mechanical properties including ultra-high tensile strength (minimum 130,000 psi yield strength), superior fracture toughness, and outstanding fatigue resistance in extreme operating conditions.

The pipe's sophisticated alloy composition provides unparalleled performance in abrasive nonferrous mining environments, particularly in copper, lithium and nickel extraction where equipment faces aggressive wear and corrosive challenges. Its enhanced strength-to-weight ratio makes it ideal for deep-hole drilling applications while maintaining structural integrity under maximum compression loads and severe torsional stresses.

Precision-engineered through specialized heat treatment and quenching processes, each length undergoes rigorous ultrasonic testing and quality verification. This seamless pipe offers superior reliability for both drill string components and production casing in critical mining operations, demonstrating exceptional resistance to stress corrosion cracking and hydrogen embrittlement - essential characteristics for maintaining operational safety and efficiency in the world's most challenging nonferrous mining projects.
