73mm DZ240 Core Barrel Core Tube Water Well Drill Pipe
1. Description of Products
Core barrel or core tube -In core drilling, a section of pipe attached to the top of the bit to hold and protect the core.When drilling, it also ACTS as a guide drill tool.
An ordinary core tube is just a seamless steel tube with a wire at both ends, with a diameter slightly smaller than that of the drill bit (2~4 mm).The length of a single core pipe is 3~ 45 meters.
In order to prevent the bending of drilling hole, several core pipes can be connected to form a long and thick diameter drilling tool.Special core pipes, such as double core pipes, are often used for drilling in special formations (such as loose and broken formations).
