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.
