TIANHE wear sub consists of a highly wear rubber sleeve, a metal stiffening liner and a sub body. The rubber sleeve is installed in the middle of sub body and some clearance is given to allow sleeve to rotate freely. The rubber sleeves are made of rubber mixtures with good wear resistance.
During drilling operation, the rubber sleeve and sub body can make a relative rotation. The rubber sleeve O.D is larger than drill pipe tool joint O.D, therefore the tool joint and drill pipes cannot come in contact with casing. The rubber sleeve on saver sub will first contact with casing. When friction between rubber sleeve and casing takes place, wearing can be reduced due to the rubber sleeve wear resistance and softness. Usage of tool joints of drill pipes and drill string tools will also be reduced.
