Stuffing Box Detail information

The Liner Hanger, also known as a liner setting tool, is a crucial component used in oil well drilling and completion operations. It is a device designed to connect and position casing pipes (known as liner) onto the casing in the wellbore and secure them in place. Made primarily of metal, the liner hanger features adjustable gripping mechanisms that provide support and fixation during the casing running process. Its main functions are to properly install and isolate the liner, protecting the wellbore from formation pressures and fluid interference. Liner hangers play a significant role in ensuring the integrity and stability of the wellbore during production and operation phases.
