Product Description
Detailed Specifications & Features
Downhole Oil & Gas Well Tools
Corrosion-Resistant Nested Wave Spring for Subsea and Downhole Wellhead Tools
Subsea exploration and downhole oil production subject equipment to extreme pressures, corrosive chemicals, and high mechanical stress. For these demanding environments, Jiangsu Sanzhong Elastic Technology Co., Ltd. manufactures high-performance Nested Wave Spring components designed for reliability in critical conditions. Our parallel-turned wave springs provide the heavy force required to seal downhole packers, safety valves, and blowout preventers (BOP).

Standard single-turn springs often lack the force needed to overcome deep-sea hydrostatic pressure, while large coil springs require too much space. Our multi-layer nested design provides high force in a small footprint, allowing downhole tools to be built with slimmer profiles. This helps operators lower drilling torque and improve well intervention efficiency.
Target Client Applications
  • Downhole Drilling Tools: Integrated into steering tools and logging-while-drilling (LWD) systems to isolate delicate electronics from high vibration.
  • Subsea Wellhead Valves: Applied to main gate valve gates to ensure metal-to-metal sealing compliance in cold marine environments.
  • Subsea Packers & Plugs: Used to apply continuous compression to elastomeric elements, maintaining long-term isolation in sour wells.
