High-Strength Oil Casing J55-114.3mm Available in Stock!

Item Details
Product Overview High-strength oil casing J55 is a type of pipe widely used in oil and gas extraction, designed to withstand high pressure and high temperature downhole. The external diameter of this product is 114.3mm, and it meets API 5CT standards, suitable for conventional oil and gas extraction, especially performing well in medium-depth oil wells. The J55 casing is made from high-quality alloy steel, ensuring its reliability and durability under complex working conditions.
Technical Specifications - Outer Diameter: 114.3mm - Wall Thickness: 6.35mm (various wall thicknesses available upon customer request) - Material: J55 alloy steel - Yield Strength: ≥ 379 MPa - Tensile Strength: ≥ 552 MPa - Length: Typically 9.14 meters (30 feet), can be customized based on customer requirements. - Connection Types: Various connection methods available, including threaded and welded connections to adapt to different downhole conditions.
Product Features The high-strength J55 casing has excellent compressive and bending capabilities, able to withstand complex pressure and temperature variations downhole. Its corrosion resistance allows it to perform excellently in environments containing acidic gases (such as H₂S and CO₂), ensuring the safety and stability of oil and gas wells. In addition, the casing surface undergoes special treatment to enhance its wear resistance and extend its service life. J55 casing uses advanced heat treatment processes during manufacturing to ensure uniform mechanical properties and microstructure.
Application Scenarios The J55 casing is widely used in conventional oil fields, shale gas wells, and coalbed methane wells, suitable for medium depth and pressure downhole environments. Due to its high strength and good corrosion resistance, the J55 casing effectively prevents wellbore collapse, ensuring the safe extraction of oil and gas. In practical applications, J55 casing is widely used in development projects of oil and gas companies, becoming an important infrastructure material.
