| The roller cones have suitable tilting angle and inlayed strengthened alloy on the cone palm which prevent | |||||||
| premature wear of the palm. | |||||||
| With the cone anti-drop technology, to maximally prevent downhole accidents caused by cone body dropout | |||||||
| after damages of bearings. | |||||||
| With the guide block or guide ring at the front of the body, the reamer has the better effects of piloting and | |||||||
| slag removal. | |||||||
| Timely cooling in the welding process prevent the seal damage caused by overheat of the cone. | |||||||
| Selection of the most suitable tooth based on different formations, thus to promote the construction efficiency | |||||||
| For large-scale reaming, weight reduction design effectively reduce the weight, linear change tendency of the | |||||||
| pipeline trajectory to reduce tne blocking when the reaming and dragging are conducted. | |||||||
| Roller cones specified for trenchless projects are developed with reasonable teeth layout and additionally | |||||||
| hardfaced cone palms, effectively enhancing the working life of the reamer in complex rock formations. | |||||||
