Outer Diameter 90MM Gr 4130 Oil Well Drill Pipe Seamless Steel Pipe for Casing Tubing
Description
This Outer Diameter 90MM Gr 4130 Oil Well Drill Pipe represents a high-grade seamless steel solution engineered for demanding downhole operations in the oil and gas industry. Manufactured from chromium-molybdenum alloy steel (AISI 4130) and produced as a seamless tube, this product combines exceptional mechanical properties with reliable performance for use in drill strings, casing, and tubing applications where precision dimensions and structural integrity are critical.
With an exact outer diameter of 90 millimeters, this pipe is designed to meet specific wellbore geometry requirements while providing the necessary strength-to-weight ratio for efficient drilling and completion operations. The Gr 4130 material composition delivers superior tensile strength, excellent fatigue resistance, and enhanced toughness compared to conventional carbon steel pipes, making it suitable for medium-depth to deep well applications where higher mechanical performance is required.
The seamless manufacturing process ensures a homogeneous microstructure without welding seams or weak points, significantly enhancing its pressure-containing capabilities and resistance to collapse under external pressures. This pipe can be heat-treated to achieve desired mechanical properties and is capable of withstanding demanding downhole conditions including high internal pressure, axial loading, and corrosive environments.
