Product Description

Toolstring Equipment Wireline Stem/Sinker Bar Standard Stem

Standard Stem
Standard Stem is used to add weights to the wireline toolstring thereby enable the descending toolstring to overcome stuffing box
fiction, well pressure and the effect of fluid viscosity that acts against the toolstring. The increase in mass also aide in converting kinetic
energy into upward and downward jarring impact.
Rule of thumb to determine the weight of a solid steel stem per foot length is:Weight (lbs/ft) =Stem OD2 x 8/3

 

Available tool sizes as shown. Weight shown is for (UN Thread) reference only. Please contact our sales office for further enquiries.
