AISI 4130 Oil Well Drill Pipe , Seamless Alloy Steel Pipe for Nonferrous Metal Mining Projects

Description

Our AISI 4130 (30CrMo) seamless alloy steel pipes are engineered to meet the rigorous demands of oil and gas drilling operations. Manufactured in strict compliance with GB/T 9808 and ASTM A519 standards, these pipes deliver exceptional strength, toughness, and fatigue resistance, making them ideal for critical applications such as drill pipes, casings, and tool joints.

With precise chemical composition control and advanced heat treatment processes, our pipes ensure superior microstructural integrity, low residual stresses, and high dimensional accuracy. They are rigorously tested for non-destructive quality assurance, guaranteeing reliability in the most challenging downhole environments.
