ASTM A519 Grade 4130 Oil Drilling Pipe , Alloy Round Pipe for Drill Rod Pipe

Description

This ASTM A519 Grade 4130 oil drilling pipe represents premium chromium-molybdenum alloy tubing engineered for demanding drilling applications. Manufactured as seamless round pipe through precision cold drawing and heat treatment processes, it delivers exceptional yield strength (minimum 100,000 psi) and superior torsional resistance for heavy-duty drill rod applications.

The pipe's chemical composition provides optimal mechanical properties including enhanced fatigue durability and excellent impact resistance in aggressive downhole environments. Its seamless construction ensures uniform wall thickness and dimensional stability, critical for maintaining performance under extreme compression loads and cyclic stresses during extended-reach drilling operations.

Certified to ASTM A519 standards, each length undergoes rigorous non-destructive testing to guarantee material integrity and performance consistency. This drill pipe is specifically designed for use in deep-well drilling, mineral exploration, and challenging geological conditions where reliability and extended service life are essential for operational efficiency and cost-effectiveness.
