Oilfield Socket Type Sinker Bars Wireline Stem Section Weight Bar
The Sinker Bar is also named Weight Bar, which is wireline stem section. The Sinker Bar is designed to provide the necessary weight / mass to be be able to deploy a wireline toolstring in the well, against well pressure.Lead Filled Stems,sometimes called Sinker bars,provide the mass required in wireline operations although they should not be used in operations where heavy jarring is anticipated.Lead Filled Stems aslo enable the toolstring to fall against the differential pressure and friction at the wireline stuffing box.
