Brief: In this walkthrough, we highlight key design ideas and how they translate to performance. Join us for an inside look at the production workshop for high-strength oilfield sucker rods, where we demonstrate the manufacturing process, from hot forging and heat treatment to CNC machining and quality control, ensuring rods meet API 11B standards for demanding oilfield applications.
Related Product Features:
  • Manufactured from hot-rolled AISI 4330 alloy steel for superior strength and durability.
  • Available in API 11B grades C, D, and K to suit light, medium, and corrosive well conditions.
  • Ends are hot-forged and machined on CNC lathes to precise API dimensions.
  • Rods undergo full-length heat treatment, including normalizing, tempering, or quenching.
  • Shot-blasted to remove scale and oxidation, ensuring a clean, polished surface.
  • Machine straightened and cold drawn to achieve required size and straightness.
  • Tested for mechanical properties including tensile strength, yield strength, and elongation.
  • Customizable lengths from 2 to 30 feet to meet specific well depth requirements.
FAQs:
  • What are the main differences between the C, D, and K grade sucker rods?
    Grade C rods are for light to medium loads in non-corrosive or shallow wells, made from carbon or manganese steel. Grade D rods, made from high-quality alloy steel, offer higher strength and are suitable for deeper wells with no or mild corrosion. Grade K rods, manufactured from Ni-Cr-Mo alloy steel, provide corrosion resistance for use in strongly corrosive shallow, medium, or deep wells.
  • How are the sucker rods tested for quality and performance?
    Each rod undergoes rigorous testing, including sample specimens cut from heat-treated material to check ultimate tensile strength, yield strength, and elongation. Rods are also checked for straightness, and forged ends are aligned with the body. Final inspection includes shot-blasting for cleanliness and machining verification with API-approved gauges.
  • What sizes and customization options are available for these sucker rods?
    Sucker rods are available in sizes from 5/8" to 1-1/8" rod diameter, with corresponding thread dimensions and lengths ranging from 2 to 30 feet. Custom lengths can be provided to suit specific well requirements, and all rods are manufactured to meet precise API dimensional standards.
