Φ50 Core Tube

Alias：British imitation drill pipe, round drill pipe, flat drill pipe, geological alloy drill pipe, conventional drill pipe in coal mine, exploration drill pipe Used for drilling construction drilling tools for coal mine water exploration, gas exploration and geological exploration. The geological drill pipes we produce include conventional drill pipes in coal mines, exploration drill pipes below Φ89mm for oil drilling and down-the-hole drill pipes for rock drilling in mines.

Application

Drilling, mining and anchoring in coal mines, mines, construction, water conservancy projects, railways, highways, bridges and tunnels and other industries. In coal mines, it is mainly used for coal mine water exploration, gas exploration, and roadway exploration.

Product advantages

The main body of the drill pipe is made of high-quality geological special alloy steel pipe, and the drill pipe joint is made of high-quality alloy structural steel. The machining accuracy of the product, the production process of friction welding first and then thread processing, ensures the precise coaxiality standard of multiple connections of drill rods during deep hole drilling. Compared with similar products, it has high bending strength and large rotational torque. , stable operation and so on.

Product parameters

Material：According to the different specifications and models, different materials are used for production. Φ34-50mm adopts DZ50 (45Mn2 four or five manganese two), and Φ60-89mm adopts R780 (36Mn2v three six manganese two vanadium) or R780 (42Mnmo7 four two manganese molybdenum seven) as a drill Rod body material, drill pipe joint uses alloy structural steel 42CRMOA material.

Taper button：Φ63.5mm, Φ73.0mm, Φ89.0mm（Drill pipe diameter）

Flat buckles are generally used for small diameter geological drill pipes. With the increase of the diameter of the drill pipe, the drilling depth and the torque of the drill pipe will increase accordingly. The drill pipe connected by the taper can ensure the accurate transmission of the torque when the drill pipe is working, and it is also more convenient to disassemble. It can also be customized according to the special needs of customers.

Drill match

The diameter difference between the drill pipe and the drill bit is the primary factor to be considered. The diameter difference refers to the difference between the diameter of the drill pipe and the drill bit. The diameter of the drilled hole is caused by the diameter of the drill bit. The diameter of the drill pipe is smaller than the diameter of the drill bit. During the drilling process, the force on the drill pipe can be reduced to the minimum extent, and there is no clear standard value for the diameter difference. **As follows:

Drill pipe diameter	Φ34mm	Φ42 mm	Φ50 mm	Φ63.5mm	Φ73 mm	Φ89 mm
Drill diameter	Φ55 mm	Φ65 mmΦ75 mm	Φ75 mm	Φ94 mm	Φ94 mm	Φ108 mmΦ133 mm
