Fiberglass Sucker Rod | Lightweight Oilfield Rods Over 140,000 psi - CNPS
CNPS Fiberglass Sucker Rod - lighter, stronger and corrosion-resistant for demanding oilfield pumping operations.
Product Overview
CNPS fiberglass sucker rods are advanced alternatives to traditional steel rods, designed for harsh oilfield operations. They offer high tensile strength exceeding 140,000 psi, excellent fatigue resistance and light weight - approximately 75% lighter than steel rods, making them easier to handle and reducing load on the pumping equipment. The rods are corrosion-resistant against acidic gases, carbon dioxide and saltwater environments, delivering a longer service life, reduced pump wear and lower energy consumption. All CNPS fiberglass sucker rods comply with API standards and oilfield equipment requirements as stated in the CNPS product documentation.
Why Choose Fiberglass Sucker Rod?
- Approximately 75% lighter than steel rods, reducing stress on surface and downhole equipment.
- Tensile strength exceeding 140,000 psi for harsh underground conditions.
- Corrosion-resistant against acidic gases, carbon dioxide and saltwater.
- Longer service life than steel rods, requiring fewer replacements.
- Reduces pump wear, lowers energy consumption and extends oil pump service life.
- Complies with API standards and oilfield operation specifications (specific API designation to be confirmed).
Fiberglass rod bodies supplied as a complete sucker-rod string solution for rod-pumped wells, with rod sizes, lengths and connections configured per the well design - confirm by model. The lightweight rod construction reduces the load on the rods by up to 75% and minimizes stress on the pumping equipment while meeting the tensile requirements of demanding wells.
- Lightweight design: load on the rods reduced by up to 75%, minimizing stress on the equipment.
- High tensile strength: withstands 140,000 psi, suitable for harsh underground conditions.
- Corrosion-resistant: withstands acidic gases, carbon dioxide and saltwater environments.
- Sour-service capability: resists corrosion of hydrogen sulfide and carbon dioxide, ensuring safe and long-lasting operation in harsh oil wells.
- Longer service life: lasts longer than steel rods, requiring fewer replacements.
- Energy saving: reduces pressure on pumping equipment, lowers energy consumption, extends oil pump service life and lowers lifting cost.
- API compliance: all CNPS fiberglass sucker rods comply with API oilfield operation specifications.

🔧Connection / Installation
Installation and make-up follow standard sucker-rod running practice for rod-pumped wells. The rod string is assembled with the recommended couplings and run with standard rod handling equipment; the 75% weight reduction makes handling easier and reduces load on the surface pumping equipment. Ensure make-up torque follows the coupling manufacturer's specification. Confirm the string design - rod sizes, lengths and coupling selection - with CNPS for the specific well conditions.
⚙️Applications
- Oil wells
- Deep wells and oil wells with high strength requirements
- Acidic wells containing acidic gases and corrosive substances (H2S, CO2)
- Oilfield pumping systems
- Harsh underground conditions with corrosive environments
💎Project Customization
CNPS can match rod size, length and coupling configuration to the well design, including deep wells and wells with high strength or corrosive requirements. Send your well data - depth, corrosive media and pumping conditions - to CNPS so the rod string can be confirmed and supplied.
