Long Spiral Drill Pipe

Product introduction:

Long spiral drill pipe can be divided into single-wall hollow drill pipe and double-wall drill pipe. When the former is drilled to a predetermined depth, the concrete is continuously poured into the concrete at the same time as the drill is raised, and then the steel cage is inserted. The latter can input air while drilling to reduce slewing resistance.
