AISI 4130 Steel Pipe Oil Well Pipe , Seamless Casing Pipe for Oil Wells
Description
AISI 4130 Steel Pipe Oil Well Pipe, a premium seamless casing pipe for oil wells, is engineered to excel in the harsh and high-stakes environments of oil and gas exploration. Crafted from high-grade SAE 4130 chromium-molybdenum alloy steel, this seamless casing pipe stands out for its exceptional structural integrity and resistance to downhole challenges.
Its precise chemical composition—featuring 0.28-0.33% carbon, 0.80-1.10% chromium, and 0.15-0.25% molybdenum—delivers outstanding mechanical properties, including a minimum tensile strength of 813 MPa and yield strength of 690 MPa. These attributes enable it to withstand extreme pressure, high temperature (HPHT) conditions, and corrosive fluids commonly encountered in deep oil wells, effectively preventing casing collapse and ensuring long-term wellbore stability.
The seamless manufacturing process eliminates weld seams, a common weak point in traditional casing pipes, while specialized heat treatments (such as quenching and tempering) enhance its toughness and fatigue resistance. Suitable for both onshore and offshore oil wells, this SAE 4130 seamless casing pipe undergoes rigorous quality checks—including ultrasonic testing, hydrostatic testing, and dimensional verification—to meet industry standards. It plays a critical role in securing the wellbore, isolating production zones, and protecting groundwater, making it an indispensable component for reliable and efficient oil well operations.
