Product Description

POLISHED ROD 


Regular polished rods are connected to polished rods coupling, and end upsetting polished rods are connected to sucker rod coupling in use. This technique ensures a perfect thread on each and every pin. 

 

• Material type 
• ALLOY STEEL: Alloy Steel is manufactured from a chromium-molybdenum alloy steel (4140) and
• designed for light to heavy loads at any depth in mild to medium corrosive well fluids that are effectively inhibited against corrosion. This polished rod has a minimum tensile strength of 125,000 PSI and has been alloyed to improve its hardenability and increase its resistance to corrosion and abrasion.
• STAINLESS STEEL: Stainless Steel is manufactured from Type 431 High Strength stainless steel. This polished rod has a minimum tensile strength of 115,000 PSI and has the best corrosion resistance properties when compared to 1045 or 4140 alloy rods. It has excellent tensile and torque strength and good toughness, making it ideally suited for progressing cavity pump application. 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 proble
