Product Description

Product Description
Reverse circulation drill pipe, also known as double-wall drill pipe, is a kind of drilling toolused for reverse circulation driling, which is composed of inner and outer layers of dril pipe(called inner pipe and outer pipe). An annular gap is for between that inner pipe and the out pipe.and the circulating medium flows to the bottom of the hole from the annular gap of thedouble-wall drill rod during drill.The central hole of the inner pipe is used to take out the circulating medium and bring thecore sample back to the surface, Each double-wall drill pipe is connected by the screw thread othe outer pipe to ensure the transmission of torque and pressure. The inner pipe is usuallyconnected by plugging, which generally only plays the role of circulating the circulating mediumThe plugging is equipped with a sealing device. Reverse circulation drilling can effectively preventhe collapse of the well wall and improve the drilling efficiency.
