Grade 4130 Chromoly Oil Drilling Pipe, High-Tensile Alloy Steel Pipe for Dill Rod Tubing

Description

This Grade 4130 Chromoly Oil Drilling Pipe represents a premium-grade seamless alloy steel pipe specifically engineered for demanding drilling applications in the oil and gas industry. Manufactured from AISI 4130 chromium-molybdenum alloy steel, this high-tensile pipe combines exceptional mechanical strength with superior durability, making it an ideal choice for drill rod tubing and other critical downhole components where reliability and performance are paramount.

The pipe's chromium-molybdenum composition provides an outstanding balance of high tensile strength, excellent toughness, and enhanced fatigue resistance, significantly outperforming conventional carbon steel pipes in demanding drilling environments. With typical yield strengths ranging from 70,000 to 100,000 psi (480-690 MPa), this material maintains its structural integrity under extreme torsional stresses, compression loads, and cyclic bending moments encountered during drilling operations.

The seamless manufacturing process ensures a homogeneous microstructure free from welds and imperfections, providing consistent mechanical properties throughout the pipe length. This chromoly drill pipe is heat-treated to achieve optimal mechanical characteristics, including improved impact resistance and better fatigue life compared to standard drilling materials. Its enhanced strength-to-weight ratio allows for deeper drilling capabilities while reducing overall string weight.
