非開挖擴孔器在非開挖工程中用于擴大先導孔
( HDD在挖溝和挖掘不實用時使用。這種鉆探技術允許一種可操縱的非開挖方式在地下鉆探。）
The hole openers are used to enlarge the pilot hole in HDD engineering.
( HDD is used when trenching and excavating is not practical.This drilling technology allows for a steerable trenchless way to drill underground.)
我們生產適用于各種地層的巖石孔器，軟巖石像石灰巖和砂巖，堅硬巖像花崗巖和玄武巖等。選擇合適的牙 掌能夠提高鉆進速度和使用壽命。噴水孔的大小可根據施工中擴孔器的孔徑設計。
We produce the hole openers for all kinds of formations, soft rock like limestone or sandstone, hard rocks like granite and basalt. Correct cutter selection can improve the ROP and working life. The nozzles can be designed according to different reamer size on different drilling conditions.
根據回擴力和鉆桿的尺寸，我們可以定制3輪,4輪,5輪或者更多輪的巖石擴孔器。絲扣類型有多種 選擇，像APl，F，FH等。
Our rock reamer can be customized with 3, 4, 5 or more rollers, depend on your pullback power and the diameter of the pipe. Our Hole openers are generally fitted with API threads, IF, FH, etc |
