CLARETECH STL STEAM VALVE LUBRICANT

High Temperature Valve Grease for Steam Injection and Geothermal Production Wellhead Gate Valves

The unique challenges operators face during enhanced oil recovery using steam injection require a highly viscous valve lubricant with high temperature capabilities to ensure the grease can withstand the harsh operating conditions to remain in the valve cavity to offer continuous lubrication and protection.

Claretech STL is a specially developed high temperature valve grease for steam injection and geothermal production wellhead gate valves used in steam and geothermal service operations, where the equipment is rated to operating temperatures up to 650°F/343°C (API 6A temperature classification Y upper temperature), particularly where high temperature, crude oil, natural gas, steam, acids, sand slurries and difficult condensates are encountered. 

It’s high temperature capabilities, water-washout performance, superior sealing capabilities and high-chemical resistance properties mean Claretech STL is ideally suited to the following applications:

  • Cyclic Steam Stimulation
  • Huff and Puff
  • Steam Injector Wells
  • Geothermal
  • Steam Flooding
  • Steam Assisted Gravity Draining (SAGD)

High Temperature Performance

  • Extreme high temperature performance of up to 650°F.
  • Able to hold its viscosity to remain stable and grease like, even at extreme high temperatures.
  • Proven to have low oil separation so the grease will not dry out or harden at the upper temperature limits (ASTM 6184).

Exceptional Cavity Retention

  • Claretech STL offers exceptional water spray off performance and is capable of withstanding high velocity and turbulent flow of fluids entering the valve cavity.
  • Advanced EP additives and corrosion inhibitors for enhanced wear protection to provide long lasting wear protection.
  • Excellent adhesion and cohesion properties to adhere to the valve's internals, providing lasting protection and ensuring easy valve actuation.

THERMAL EXPANSION SAFE LUBRICANT

Claretech STL is a temperature and pressure stable valve lubricant, and there is no risk of thermal expansion causing increase pressure on the valve bonnet studs.
