Mechanical Hydraulic Shock Sub Type DHJ
The mechanical and hydraulic shock sub type DHJ is a two-function shock sub that absorbs the pulsate and
shock from drill tools by compressing spring and SI oil to store the energy. It is used for reducing vibrations caused by hard formation drilling and keeping the drill bit firmly on the bottom, so that it helps to reduce drill string connection fatigue and prolong drill string life.
