Gr 4130 114mm OD Oil Drilling Pipe Chromoly Steel Tube for Seamless Casing Tubing

Gr 4130 OD 114 Oil Drilling Pipe Chromoly Steel Tube for Casing Tubing

Product Overview

This Gr 4130 OD 114mm Oil Drilling Pipe represents a high-performance chromoly steel tube specifically engineered for demanding casing and tubing applications in the oil and gas industry. Manufactured from AISI 4130 chromium-molybdenum alloy steel with a precise 114mm outer diameter, this seamless pipe delivers exceptional mechanical properties and reliability for critical downhole operations in both conventional and challenging drilling environments.

The pipe's chromium-molybdenum composition provides an optimal balance of high tensile strength, excellent toughness, and superior fatigue resistance, significantly outperforming conventional carbon steel pipes in demanding drilling applications. With typical yield strengths ranging from 550 MPa to 750 MPa, this material maintains its structural integrity under extreme torsional stresses, compression loads, and cyclic bending moments encountered during drilling and production operations.

The seamless manufacturing process guarantees a homogeneous microstructure free from welds and imperfections, providing consistent mechanical properties throughout the pipe length. This chromoly drill pipe undergoes precise heat treatment including quenching and tempering to achieve optimal mechanical characteristics, including improved impact resistance and enhanced fatigue life compared to standard drilling materials.
