Brief: Discover how Grade 4130 Chromoly Oil Drilling Pipes are precision-straightened for optimal performance in demanding oil and gas drilling applications. This high-tensile alloy steel pipe offers unmatched strength and durability for drill rod tubing.
Related Product Features:
  • Manufactured from AISI 4130 chromium-molybdenum alloy steel for exceptional mechanical strength.
  • Seamless construction ensures a homogeneous microstructure free from welds and imperfections.
  • Heat-treated for improved impact resistance and better fatigue life compared to standard materials.
  • High tensile strength with yield strengths ranging from 70,000 to 100,000 psi (480-690 MPa).
  • Enhanced fatigue resistance for superior performance under cyclic loading conditions.
  • Good machinability allows for easy threading and connection manufacturing.
  • Ideal for drill rod tubing, core drilling, and downhole tool components in oil and gas exploration.
  • Available in various sizes (O.D.: 4 to 219mm) and lengths up to 13500mm.
Faqs:
  • What makes Grade 4130 Chromoly Oil Drilling Pipes superior to conventional carbon steel pipes?
    Grade 4130 Chromoly pipes offer higher tensile strength, better toughness, and enhanced fatigue resistance due to their chromium-molybdenum composition, making them more reliable in demanding drilling environments.
  • What are the typical applications for these drilling pipes?
    These pipes are commonly used in drill rod tubing for oil and gas exploration, core drilling, downhole tool components, mining, and geological exploration drilling.
  • What are the mechanical properties of Grade 4130 Chromoly pipes?
    The pipes have a tensile strength of 560 MPa (81200 psi), yield strength of 460 MPa (66700 psi), and elongation at break of 21.50%, ensuring durability and performance under extreme conditions.
