Quenched Plunger Forgings for Oil and Gas Extraction

Quenched plunger forgings are widely used in industrial scenarios such as the oil, gas, petrochemical, and chemical industries, where they need to withstand high pressure, friction, and harsh conditions, due to their high strength, excellent wear resistance, and corrosion resistance. Plungers are typically critical components in hydraulic systems or pump equipment. Forgings that have undergone quenching treatment have higher hardness and toughness, which can significantly improve their service life and reliability. The following are the main application areas for quenched plunger forgings:

1. Oil and Gas Industry:
   • Quenched plunger forgings are used in high-pressure water injection pumps, mud pumps, or fracturing pumps for oil and gas extraction and transportation systems.
   • They can withstand high pressure, high temperature, and corrosive media (such as environments containing hydrogen sulfide or chlorides), making them particularly suitable for deep well drilling and fracturing operations.
   • Materials commonly used are high carbon steel (such as 35CrMo) or stainless steel, which are further enhanced in wear resistance and fatigue resistance after quenching.
2. Petrochemical and Chemical Industry:
   • Used in chemical pumps, metering pumps, or plunger pumps to handle corrosive liquids, acid-base solutions, or high-temperature fluids.
   • Quenched plungers perform excellently when handling high-viscosity or particle-containing media, reducing surface wear and seal failure.

Common Materials:

• High Carbon Steel: Such as 35CrMo, 42CrMo, suitable for high strength and wear resistance requirements.
• Stainless Steel: Such as 316L, 17-4PH, suitable for corrosive environments.
• Nickel-based Alloys: Such as Hastelloy C-276 or Inconel, used for extreme corrosion and high-temperature conditions.
