Kelly Pin drilling tools are essential components used in the oil and gas industry for drilling operations. These tools are designed to securely connect the drilling rig’s Kelly bar to the drill pipe, providing a reliable and efficient transfer of torque and rotational power.
[pdf] The laser cutting screw air compressor (4-in-1) is a space-saving integrated solution that combines an air storage tank, compressor, refrigerated dryer, and precision filter. It is perfectly suited for laser cutting, offering adjustable pressure (up to 16 bar) and plug-and-play convenience.
[pdf] We have developed a laboratory-based, test bench robotic system that drives an active drill into concrete while simultaneously measuring these health-related exposures and productivity. The measurement methods follow guidelines from national and international standards.
