AISI 4130 Steel Pipe Oil Well Pipe , Seamless Casing Pipe for
Nonferrous Metal Mining Projects
Description
This AISI 4130 steel pipe represents high-performance seamless
casing specifically engineered for challenging nonferrous metal
mining projects. Manufactured from chromium-molybdenum alloy steel,
it delivers exceptional mechanical strength, superior abrasion
resistance, and reliable performance in corrosive mining
environments.
The seamless construction ensures maximum structural integrity for
casing applications in copper, nickel, zinc, and lithium mining
operations. Its enhanced yield strength and torsional resistance
provide optimal support in unstable geological formations, while
the alloy composition offers excellent resistance to acidic mine
waters and abrasive slurries.
Precision-engineered through controlled heat treatment, this casing
pipe maintains dimensional stability under heavy loading
conditions. Certified to international quality standards, it
ensures extended service life and reduced maintenance requirements
in both shallow and deep mining applications, providing reliable
ground support in the most demanding nonferrous mining projects.
