Sucker Rod with Various Grades and Specs

Introduction

Sucker rod is the common equipment in the oil extraction. It is manufactured through many process including the testing, straightening and forging. The sucker rod is placed between the polished rod and oil well pump. To deliver power. Sucker rod is manufactured from high quality carbon steel and alloy steel, which is conform to the API Spec 11B standard. Sucker rod has various types including the common sucker rod, hollow sucker rod and FRP sucker rod. Commonly we use the sucker rod coupling to connect the sucker rod. The sucker rod also has various specs to fit different environments and applications.

Production

  • For common sucker rod:
    Raw Material Test → Cold Straighten → Cut → Forge → Hot Treatment → Hot Alignment → Shot Blasting → Rod Head Machining → Assembly → Protective Cap → Package → Aczoiling Treatment.
  • For extra high tensile sucker rod:
    Raw Material Test → Cold Straighten → Cut → Forge → Quenched And Tempered → Hot Treatment → Hot Alignment → Shot Blasting → Rod Head Machining → Surface Quenched → Assembly → Protective Cap → Package → Aczoiling Treatment.
The sucker rod is in the process of shot blasting.

Applications

The sucker rod is widely used in the oil extraction industries. The different grade sucker rod can be applied in different applications.

  • Grade C sucker rod: Moderate strength, has a certain degree of resistance to the sulfide stress cracking, it is suitable for sour environments.
  • Grade D sucker rod: The grade D sucker rod is manufactured from high quality heat treated steel alloy, which has high tensile and yield strength, it is can be used in the non-corroding or mildly corroding environments.
  • Grade K sucker rod: The grade K sucker rod has a good corrosion resistance in H2S, CO2, and NaCl media, it is widely used in corrosion environments.
  • Grade H sucker rod: This is a type of sucker rod with extra high tensile strength it is ideal for deep and large wells.
