Product Description
Introduction
1. Introduction of polished rod
The polished rods are used to connect sucker rod and pump unite.
2. Manufacturing specification: API 11B
3. Material
3.1. Chemical Composition
The chemical composition of polished rods are any composition of AISI recommended series steels that conform to chemical and mechanical property requirements listed below. The chemical and composition and limits shall be detailed in the material specification of the manufacturer.
A) Carbon steel:A1SI 1035-10507.
B) Stainless steel: AISI 304/316 or 431 7.
C) Alloy steel:
1) AISI 4120-41407 :
2) AISI 4315-43407
3] AISI 4615-46257
4) AISI 8620- 86307
Chemical composition of polished rod liners shall be as specified by the manufacturer. Steel polished rod liners shall be sprayed metal coated.
Chemical analysis shall be performed on each mill heat of steel used in the manufacture of polished rods. This analysis shall be performed in accordance with ASTM A751. A material certification is an acceptable means to conform to this requirement.
3.2 Mechanical Properties for Finished Product
The mechanical properties of polished rods conform to the strength values as follows:
A) For carbon steels listed in B.3.2,the ultimate tensile strength shall be in the range of 90,000 psi to 160,000 psi(621 MPa to 1,103 MPa };
B) For alloy steels listed in B.3.2,the ultimate tensile strength shall be in the range of 95,000 psi to 160,000 psi(655 MPa to 1,103 MPa };
C) For stainless steels listed in B.3.2,the minimum ultimate tensile strength shall be 70,000 psi (482MPa) for 304/316, and 90,000 psi(620 MPa) for 431.

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.
