Pro-RodTM manufactures the following types of continuous rod to meet any pumping condition.
- Type 620C Grade D (Carbon)
- AISI 1536M Carbon-Manganese Alloy Steel. Designed for medium to heavy loads at any depth in non-corrosive well fluids.
- Type 780M Grade D (Alloy)
- AISI 4120M Chromium-Molybdenum Alloy Steel. Designed for heavy rod loads at any depth in mild to medium corrosive well fluids that are effectively inhibited against corrosion attack. This grade has been alloyed and effectively heat-treated to resist corrosion and fatigue.
- Type 750N Grade D (Special alloy)
- AISI 4320M/4330M Nickel-Chromium-Molybdenum Alloy Steel. Designed for heavy loads at any depth in corrosive well fluids that are effectively inhibited against corrosion attack. This grade had been alloyed and then effectively heat-treated to maximize its corrosion and fatigue resistance.
- Type 960M Special High Strength Grade
- AISI 4120M Chromium-Molybdenum Alloy Steel. Designed for extra heavy loads at any depth in mild to medium corrosive well fluids that are effectively inhibited against corrosion attack. This grade has been alloyed and effectively heat-treated to resist corrosion and fatigue.
- Type 970N special High Strength Grade
- AISI 4320M/4330M Nickel-Chromium-Molybdenum alloy Steel. Designed for extra heavy loads at any depth in corrosive well fluids that are effectively inhibited against corrosion attack. This grade has been alloyed and effectively heat treated to maximize its corrosion and fatigue resistance.
- Custom Grades & Strenghts
- Available upon request.
All Grades are suitable for both Reciprocating and Rotary application.
