挤扩式扩孔器
挤扩式扩孔器本体采用优质合金钢，经淬火调质。一体式芯轴，特质的耐磨合金削齿，使进尺速度更快，内部采用分水隔仓设计，使其在空洞中泥浆浮力的作用下，重量更轻，扭矩更小，更有效的防止梨型孔的形成。根据各种地层设计不同长度直筒段，使其成孔效果更好。（直径150mm-1800mm可根据客户要求定制）
Barrel Reamer
The body of the barrel reamer is made of high-quality alloy steel, which has been quenched and tempered. With the one-piece mandrel and the special wear-resistant alloy cutting teeth, the reamer can move faster. The internal is water compartment design, so that under the action of mud buoyancy in the cavity, the weight is lighter, the torque is smaller, and it is more effective to prevent Formation of pear-shaped holes. Different lengths of straight barrel sections are designed according to various formations to make the hole-forming effect better. (diameter 150mm-1800mm can be customized according to customer requirements).挤扩式扩孔器参数
