Mechanical properties of steel sucker rods

API Grade K,C Minimum yield strength 60000psi ,Tensile strength 90000psi-115000psi

API Grade D Minimum yield strength 85000psi ,Tensile strength 115000psi-140000psi

 

When determining the allowable stress range and allowable stress of the sucker rod string, it is recommended to use the modified Goodman diagram. When used in non-corrosive conditions, the basic stress range is provided here. Since all well fluids are corrosive to a certain extent, and because the corrosiveness of well fluids varies greatly, if there is no 100% corrosion inhibition, the stress value is determined according to the Goodman diagram and the severity of the corrosion is determined , It is extremely important to use the appropriate service factor to modify it. Each user should select the service factor based on experience. Although the service factor is less than 1 under normal circumstances, it may be greater than 1, which is inversely proportional to the change in the degree of corrosion.
