Grade and Mechanical Properties
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.
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.
