   Duct mounted reverse circulation drilling rods

 

Duct mounted reverse circulation drilling rods with top quality

Duct mounted reverse circulation drilling rods is mainly applies in reverse circulation drilling. The high pressure air coming from air compressor passes through air tube which is inserted in single wall drill pipe, and then pours air into mud through the lower outlet of air tube to form the combination of mud and air, the proportion is lower than that of between drill pipe and wall so that the negative pressure forms. Consequently, the mud outside the drill pipe passes through lower part of drill bit to power swivel with cuttings.
