Geological Drilling Pipe
Overview: The Geological Drilling Pipe is a specialized drilling tool designed for the demanding conditions of geological exploration. Its primary function is to transmit the torque from the drilling rig to the drill bit at the bottom of the wellbore and to circulate the drilling fluid. This pipe is crucial for the efficiency and safety of drilling operations.
Material Selection: Our Geological Drilling Pipes are crafted from high-quality materials to ensure durability and performance. The pipe bodies typically use specialized alloy steel tubes such as R780 and DZ50, known for their strength and resistance to harsh drilling conditions.Geological Drilling Pipe
Structural Design: The design of our Geological Drilling Pipe uses alloy steel tubes with thickened ends, precision machined to create small pitch tapered threads. These threads are then connected to locking joints, enhancing the pipe’s overall strength, bending resistance, and welding integrity.
Common Types:
We offer a variety of Geological Drilling Pipes to suit different drilling specifications. Available in various diameters and lengths such as Φ3m and Φ4m, these pipes come in multiple specifications to meet the needs of different drilling projects. Additionally, we provide conventional drill pipes specifically for coal mine tunneling, suitable for water and gas exploration.
Key Processes:
The manufacturing of our Geological Drilling Pipes involves several critical processes including quenching, friction welding, and thread machining. Friction welding is particularly important because it joins the pipe ends under pressure, using the relative motion between the contact surfaces to create a weld at temperatures close to but below the melting point.
Thread machining is performed using automated equipment to ensure precision in every product.
Application Fields:
Our Geological Drilling Pipes are widely used in drilling operations in coal seams and near-coal geological conditions, as well as in coal mine dewatering and gas emission drilling construction. They are also applicable in anchoring and drilling construction for geophysical and water conservancy projects.
Specifications and Standards:
Our products adhere to various industry standards such as API Spec 5CT, API Spec 5B, BG Series, and are available in grades like DZ40, DZ50, DZ60, STM-R780, BG850ZT, and more. The seamless pipes are manufactured according to GB/T8162-2008, ensuring dimensional accuracy, excellent machining performance, and stable mechanical properties.
Advantages of Hot Rolled Geological Drilling Pipe:
Hot rolling improves the structure and mechanical properties of steel pipes by refining steel grains and eliminating microstructural defects. It also helps in welding any casting bubbles, cracks, and porosity under high temperature and pressure, enhancing the pipe’s overall quality and performance.
