Onshore Cementing Systems

Gulfstream Services Inc.'s RCH (rotating cement head) line is designed to drop plugs, darts or balls of any type or length during cementing or circulating applications, all while reciprocating and rotating string weights up to 3 million pounds.

Our RCH line has been engineered with a modular design and can be configured with a swivel, pump-in-sub, or as a stand-alone cement head, depending on your particular application and needs.

GSI’s RCH Top Drive Cement Heads have been successfully deployed on over 3,500 jobs worldwide.

  • No Line of Sight Requirement. 
  • Manual operations performed with a standard Kelly valve wrench 
  • Only requires 1/4 turns (90°) to launch objects for an "immediate release".
  • Ability to rotate and reciprocate simultaneously. 
  • Modular design allows an infinite number of objects to be loaded/launched. Limited by derrick height.
