Product Description

Product Description

The polished rod is the uppermost joint in the string of sucker rods used in a rod pump artificial-lift system. The polished rod enables an efficient hydraulic seal to be made around the reciprocating rod string.Currently, polished rods are made from AISI 4130 and 4140 alloy steel. 
High strength stainless steel with a minimum tensile strength of 115,000 PSI. This product outperforms
1045 or 4140 in corrosive environments. Its excellent tensile and torque strength makes it ideally suited for PC Pumps (Progressive Cavity).This grade exhibits excellent resistance to a wide variety of corrosive media, including salt water. It is designed for any loads at any depth where corrosion is a problem.
