Chain Integration Upgrade To Break Through And Enhance Efficiency: Pathways for Domestication of Core Components And Cost Optimization of Rotary Drilling Rigs

    As the core equipment in the field of infrastructure construction, the maturity of the rotary drilling rig's industrial chain directly determines the competitiveness of the industry. For a long time, the pain point of relying on imported core components has not only increased the production cost of the entire machine, but also constrained the independent development of the industry. Nowadays, with the continuous advancement of technological breakthroughs, the localization process of core components of rotary drilling rigs is accelerating, which not only solves the "bottleneck" problem, but also opens up broad space for cost optimization of the entire industry chain, promoting the transformation of the industry from "scale expansion" to "quality and efficiency improvement".

    Breakthrough in localization of core components, laying a solid foundation for independent industrial chain. The core components of rotary drilling rigs include drill rods, hydraulic systems, transmission systems, etc., which were once key bottlenecks restricting the development of the industry. Previously, high-end rotary drilling pipes relied heavily on imports, with domestic low-strength products having a service life of only 500 hours, and imported products being expensive and difficult to guarantee delivery times. In recent years, upstream enterprises such as Hualing Henggang have collaborated with downstream host manufacturers to successfully achieve the localization of high-end rotary drilling pipe, increasing the domestic market share to over 50% and extending the service life to over 3000 hours. It has become a core supplier for leading enterprises such as XCMG, Sany, and Zoomlion. In the field of key systems such as hydraulic and transmission, XCMG and other enterprises have established a sound research and development system. The independently developed fully electronically controlled hydraulic multi way valve has achieved technological breakthroughs, and the transmission system solution supports the performance upgrade of large tonnage rotary drilling rigs, gradually breaking the dependence on imports and realizing the independent controllability of core components.

    Domestic substitution continues to deepen, unleashing the potential for cost reduction across the entire chain. The cost optimization effect brought by the localization of core components runs through the entire process of research and development, production, and supply chain. In terms of procurement costs, the tariffs, transportation, and agent premiums for imported core components are relatively high, while domestically produced components can directly reduce procurement costs by 30% -50%, significantly reducing the production cost of the entire machine; In terms of supply chain costs, local support reduces cross-border transportation cycles and inventory backlog risks, shortens production and delivery cycles, reduces warehousing and capital occupation costs, and facilitates rapid adjustment of production capacity according to market demand, thereby enhancing supply chain flexibility. In addition, the R&D iteration of domestically produced components is more in line with domestic construction conditions, which can reduce the investment in adaptability transformation. At the same time, the maintenance cost in the later stage is significantly reduced, further amplifying the cost advantage and helping host manufacturers improve product cost-effectiveness and marketcompetitiveness.

    Collaborative efforts in the industrial chain are being made to broaden the boundaries of cost optimization. The localization of core components is not a single breakthrough, but the result of upstream and downstream collaborative upgrading. Upstream raw material enterprises focus on improving performance and cost control, optimizing production processes, and reducing raw material losses; Midstream host manufacturers integrate supply chain resources, promote standardized and modular production of core components, and improve production efficiency; The downstream application side promotes precise iteration of the industrial chain through large-scale procurement and customized demand feedback. Taixin Machinery and other enterprises focus on segmented scenarios, develop small modular rotary drilling rigs, adapt to diverse construction needs at home and abroad, and further compress unit production costs through large-scale production and localized matching. At the same time, the digital and intelligent upgrading of the industrial chain promotes the efficiency improvement of the entire production and operation process, indirectly reducing labor and management costs, and forming a synergistic effect of cost optimization.

    The localization of core components is the core lever for upgrading the rotary drilling rig industry chain, and it is also the necessary path for the industry to achieve high-quality development. In the future, with the continuous iteration of technology and the deepening of industrial chain collaboration, the localization rate of core components will further increase, and the space for cost reduction will continue to be released. At the same time, relying on the advantage of localization, domestic rotary drilling rig enterprises will better participate in global competition, promote the leap of China's construction machinery industry chain from a "manufacturing power" to a "manufacturing powerhouse", and provide solid support for the high-quality development of the infrastructure industry.
