A Metal Polished Rod is an essential component in oilfield operations, specifically used in the connection between the sucker rod pump and the pump unit. The polished rod ensures the transfer of mechanical power from the surface equipment to the downhole pump, which is responsible for lifting oil or water from the well. These rods are made from high-quality alloy steel or stainless steel to ensure strength, durability, and resistance to harsh downhole conditions.

| Tensile Strength | 621 - 965 MPa, depending on grade |
| Hardness | 16 - 42 HRC based on grade and material type |
| Processing | Cold drawn, heat-treated, and polished for smoothness |
| Coupling Type | Threaded, collar-type, high-tensile couplings |
| Applications | Well drilling, water lifting, oil and gas extraction |
| Compliance | Manufactured to meet industry standards (API compliance) |
Each polished rod is connected using couplings designed to withstand mechanical stress without unscrewing or loosening during operation. Couplings align seamlessly with the rod ends and are machine-checked to ensure a secure fit. This setup enhances operational reliability, especially in deep wells, where secure rod connections are critical for smooth operation.
Rods undergo a meticulous heat-treatment process to achieve high mechanical performance, including quenching and tempering to increase hardness and tensile strength. Each rod’s surface is cold-drawn and polished to a mirror-like finish, reducing friction during movement and extending rod life.
Q1: What grades are available for the polished rods?
A: We offer multiple grades, including C, D, K, KD, HL, and HY, to cater to varying needs for strength, plasticity, and corrosion resistance.
Q2: Can these polished rods withstand corrosive environments?
A: Yes, certain grades like K and KD are specifically designed for use in mildly corrosive to highly acidic media, ensuring durability in challenging environments.
Q3: How are the couplings secured to avoid loosening during operations?
A: Each coupling is precisely machined and securely aligned with the rod body. Our design and threading process reduce the risk of loosening under mechanical stress.
Q4: Are these rods compliant with industry standards?
A: Absolutely, all rods are manufactured to comply with the API standards for quality and performance.
Q5: What maintenance is required to ensure longevity?
A: We recommend regular inspections for wear and tear, reapplying corrosion-resistant coatings as necessary, and checking coupling tightness periodically to maintain optimal performance.
Q6: Can the rods be customized to specific lengths?
A: Yes, we offer customization in rod lengths, diameters, and even material grades to meet specific operational requirements.
To prevent damage and corrosion during transit, polished rods are packaged with at least four layers of protective wrapping. Each rod is labeled for easy identification, including specifications such as length, diameter, grade, and material type.
