Detailed Product Description

Outer Diameter 90MM 4130 Oil Drilling Pipe Alloy Steel Pipe for Casing Pipe

This AISI 4130 30CrMo Chromoly Alloy Oil Drilling Pipe represents a premium-grade, heavy-wall seamless steel pipe specifically engineered for the most demanding casing and production applications in the oil and gas industry. Manufactured from chromium-molybdenum alloy steel conforming to both AISI 4130 and 30CrMo specifications, this robust piping solution combines exceptional mechanical strength with superior corrosion resistance.

The pipe's heavy-wall design provides enhanced collapse resistance and superior structural integrity, enabling it to withstand extreme external pressures, high axial loads, and severe mechanical stresses encountered in deep well and high-pressure applications. The chromium-molybdenum alloy composition delivers an optimal balance of high tensile strength, excellent toughness, and improved fatigue resistance compared to conventional carbon steel pipes.
