Specification
B19 Coal Mine Drill Pipes manufactured by Tianlong are tailor-made for underground mining applications. Crafted from premium materials with a primary focus on safety, these drill pipes meet the rigorous operational requirements of coal mining.
B19 Drill Pipe for Coal Mining: Precise Threading
The threading of B19 coal mine drill pipes is exceptionally precise. The M141.5 threads undergo high-precision machining, with thread profiles, pitch, and fit tolerances strictly adhering to industry standards. Verified through torque tests, they ensure secure and seamless connections with drilling equipment, minimizing the risk of loosening to the greatest extent. The thread surface is carburized and quenched, achieving high hardness and wear resistance, thus maintaining thread accuracy even after hundreds of disassembly cycles.
Durable Square Teeth
The 16x6mm square tooth design enhances torque transmission efficiency. Compared with trapezoidal or rectangular teeth, the vertical tooth surface of square teeth enables 90° right-angle power transmission, reducing angular loss. In extreme working conditions such as hard rock drilling, the power attenuation is lower than that of traditional tooth shapes, extending the service life.
B19 Drill Pipe for Coal Mining: Adjustable Length
With a length range of 0.50 meters to 2.50 meters, modular design achieves drilling flexibility for "combination on demand":
- 0.5-1.0m short-length drill pipes are suitable for advanced detection in coal mine roadways and shallow construction of gas drainage holes;
- 1.5-2.0m standard-length drill pipes serve as the main specification for conventional coalbed methane drainage and geological exploration holes;
- 2.5m ultra-long drill pipes are specially designed for kilometer-deep holes, effectively reducing connection interfaces per pipe and minimizing the risk of slurry leakage in deep-hole operations.
B19 coal mine drill pipes manufactured by Tianlong are the ideal choice for coal mining companies seeking reliable tools. Even in the most challenging mining environments, Tianlong's B19 drill pipes provide reliable supply support for equipment components.
Precautions for use
1. When making holes, be steady and appropriately reduce the pushing air volume. Avoid working the drill rod in a bent state; otherwise, the service life of the drill rod will be shortened.
2. During the drilling and withdrawal processes, try to avoid bending and subjecting the drill rods to force to increase their service life.
3. The air volume of the rock drill should be adjusted according to the on-site conditions (rock conditions) to ensure normal rock drilling operation.
4. For rock conditions where the drill bits are stuck, cross-shaped drill bits should be used.
5. Users are not allowed to change the structure of the drill rod at will or use it after reprocessing, so as not to affect the normal service life of the drill rod.
