The sinker bar Type SHG is designed to provide additional thrust load acting on the tool, instrument or equipment lowered into the borehole.
The sinker bar is utilized in tubing (T) strings, in sets of the downhole equipment lowered into the borehole using a cable rope or flexible coiled tubing (CT), when doing work using CT units and when operated dry.
The sinker bars are manufactured in the nominal diameters of 38, 45, 54 and 66 mm.
