Wear Sub
During saver sub drillingoperation, major wear and tear wear often take place between drill pipes and casings. Wear sub is used to avoid the wear between drill pipes, tool joints and casings. With features such as compact structure and easy operating, wear sub can prolong the service life of drill pipe and casing and reduce the vibration and trembling of drilling tools. It can also limit the contact friction.
Features:
Our wear drill stem subsconsist 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, rubber sleeve O.D is larger than drill pipe tool joint O.D, so the tool joint and drill pipes can not contact with casing. The rubber sleeve on saver sub will firstly contact with casing. When friction between rubber sleeve and casing takes place, wearing to casing can be reduced due to the rubber sleeve features such as wear and soft, at the same time, consumption to tool joints of drill pipes and drill string tools will be decreased.
