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.
