Product Description

Petroleum Stainless Steel Polished Rods API 11B

Polished Rods and Couplings
Polished rods and couplings are designed to handle the running torque and entire axial load generated by the weight of rod string.
Features
• Handling the complete string load;
• Transmitting sufficient torque to drive PCP;
• Ensure the sealing with drive head sealing device
• Ensure Flush-By operation

 

Polished Rod
A polished rod is the top rod in a rod string. It is made of carbon steel, stainless steel or other materials, mainly used to connect the oil well pumping unit and rod string.
Polished rod has the characteristics of high tensile strength, smooth surface and long service life. It can be used with sucker rods and hollow sucker rods.
Our polished rods are produced strictly in accordance with API Spec 11B. We provide three types of polished rods: ordinary polished rod, polished metal spraying rod, and single-ended upset polished rod.
