Stuffing Box Detail information
The liner hanger, also referred to as a liner setting tool, is an essential element utilized in oil well drilling and completion activities. This device is specifically engineered to attach and position casing pipes, known as liners, within the wellbore casing and secure them in place. Constructed predominantly from metal, the liner hanger incorporates adaptable gripping mechanisms that offer support and fixation while the casing is being run. Its primary duties include the proper installation and isolation of the liner, safeguarding the wellbore against formation pressures and fluid interference. Liner hangers play a pivotal role in upholding the integrity and stability of the wellbore throughout the production and operational phases.
