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: suitable for use in shallow Wells and non-corrosive 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.
