簡介：
反循環(huán)鉆桿(雙壁鉆管)由外管、內(nèi)管組成，并配有密封機(jī)構(gòu)(通常是O型圈)保持鉆具的密封性?？諝馔ㄟ^內(nèi)外管向下吹進(jìn)沖擊器，排渣通過內(nèi)管中部完成。由于反循環(huán)鉆桿在鉆進(jìn)的過程中要承受高度摩擦，傲石捷只用高級硬化處理過的合金鋼生產(chǎn)鉆桿和接頭。

General Introduction:
A RC drill rod (also as dual-wall drill pipes) comprises an outer and inner pipe with a sealing system (usually O Rings) to keep the drill string pressurized. Air is blown between the walls of the inner and outer pipes down to the hammer while the air forces the cuttings back up through the centre of the inner pipe. As RC drill rods are subjected to high wear in the drilling process Acedrills use only the high quality hardened alloy steel for the both rods and tool joints.
