JS406-4×15 Square Drill Pipe
As a professional equipment designed for high-efficiency drilling scenarios, the JS406-4×15 square drill pipe defines reliable quality with precise specifications. Its standard model is JS406-4×15, with a maximum drilling depth of up to 57 meters. It can flexibly adapt to various drilling rig models and integrate into the existing operation system without additional adjustments, significantly reducing equipment matching costs and time.
In response to customers’ customization needs, the kelly bar of this drill pipe adopts a iconic yellow appearance, which not only has high visual recognition but also meets the safety warning requirements of industrial scenarios. Its core performance is even more breakthrough: it not only has outstanding high-strength characteristics to withstand the impact and torque from complex rock formations, but also possesses excellent high-fluidity advantages to reduce the circulation resistance of drilling fluid. At the same time, relying on the reliable high-stability design, it ensures no deviation during long-term continuous operation, effectively prolongs the overall service life, and reduces the frequency of later maintenance.

JM Rotary Drilling Rig

JM Kelly Bar

Advantages of the JM Kelly bar
    JM adopts advanced international key-type distribution technology, which integrates the internal and external keys to enhance the reliability and performance of the drill pipe.
All the drill pipes are made of high-strength alloy quality pipes to ensure the dimensional accuracy of the drill pipes, as well as excellent mechanical properties and welding adaptability. Special heat treatment for secondary strengthening is carried out on special steel pipes (such as core pipe steel, etc.), significantly improving the torsional bearing capacity of the drill pipe. All the key strips of JM drill pipes are made of high-strength, fully high-quality alloy structural steel, and undergo comprehensive strengthening treatment. The inner key adopts an integral arc-shaped plate structure, significantly improving the wear resistance and lifespan of the inner and outer key strips, thereby reducing the failure rate and maintenance of the drill pipe. We also make reasonable pipe system configurations to maximize the thickness of the drill pipe key strips and the wall thickness of the steel pipe, enhancing the torque transmission and pressure drilling capabilities of the drill pipe, and reducing the occurrence of problems such as stuck rods, bent rods, and rolled keys.
    The unique double retaining ring structure increases the guiding length during the full extension of the drill pipe, solving the problem of easy deformation at the pipe end, improving the coaxiality and resistance to bending during full extension, and reducing the probability of inclined holes during pressure drilling. We use professional drill pipe technologies for deep holes, hard rock, and multi-sand pile holes, along with optimized construction plans and a strong construction technical team, eliminating difficulties encountered in complex stratum construction.
JM drill pipes are the preferred choice for improving drilling efficiency and achieving maximum benefits!

Fully automatic laser cutting machine

 The fully automatic laser cutting machine is a precision processing equipment for large gantry milling machines. It can ensure that the machine tool has excellent seismic resistance, high rigidity and stability. It adopts an integral steel welding structure. After annealing to eliminate internal stress and secondary vibration aging treatment for fine processing, it is made.
    This improves the stability of the machine tool. It is driven by dual motors simultaneously on both sides, with high torque servo motors, high-precision linear guides, and the bed adopts a unique segmented assembly mechanism. The material platform track is assembled in a split manner and integrated as a whole. This ensures that the service life of the machine tool is not affected by mechanical gravity and avoids deformation of the machine tool, meeting the requirements of visual sensory design. Facing different production task demands, it plays an important role in the long-term stability of the cutting of thick plates.

Intelligent welding machine operator

This intelligent robot workstation adopts various specifications of arc welding robot arms provided by FANUC, which meets the demands of the mechanical industry. At the same time, we provide a complete welding system to offer customers a comprehensive solution.
    It can stabilize and improve the welding quality, ensuring its uniformity; increase productivity, allowing for continuous production for 24 hours a day; improve the working conditions for workers, enabling them to work in harmful environments for a long time; reduce the requirements for workers’ operational skills; shorten the cycle for product modification and replacement, and reduce the corresponding investment in equipment; achieve automated welding for batch products; save floor space.
