Sino-Stone Cooperation Promotes Localization of Major Equipment to Meet Energy Structure Adjustment

2025-10-03 07:04:09
The China Petroleum and Petrochemical Equipment Industry Association (commonly known as the China Stone Association) recently held its working conference and sixth member congress in Beijing. During the event, Wang Jiming, former president of Sinopec Corp., was elected as the chairman of the sixth council. The association, which was reorganized and renamed the China Shipbuilding Association, has now prioritized the localization of major petrochemical technology and equipment as a key focus for future initiatives. According to Zhao Zhiming, the executive vice chairman of the association, the China Stone Association was founded in 1985. Initially, it aimed to break down barriers between departments, industries, regions, and ownership structures. However, for many years, it remained closely tied to government functions. After the 2002 election, the association began reforms aligned with international standards. Leaders from major companies such as PetroChina, Sinopec, and CNOOC have taken turns serving as chairmen. Today, the association includes 160 governing units and 867 member organizations. Currently, the association is focusing on the localization of key petrochemical technology and equipment, a goal directly linked to the State Council's recent "Opinions on Accelerating the Rejuvenation of the Equipment Manufacturing Industry." This policy outlines three main requirements for the oil and petrochemical equipment sector: promoting localization through large-scale projects, introducing and adapting foreign technologies for independent development, and achieving domestic production of million-ton ethylene equipment. It also emphasizes developing offshore oil engineering equipment, large transport vessels, floating production tanks, and LNG carriers, as well as coal chemical equipment to meet national energy needs. Zhao emphasized that innovation and R&D are essential for successful localization. He cited Sinopec’s experience over the past two decades, highlighting four key lessons: first, strong leadership and organizational coordination are crucial, with top leaders taking full responsibility. Second, strict management and procedural discipline must be maintained, with dedicated offices overseeing localizations. Third, the principle of seeking truth from facts should guide decision-making, balancing risk and breakthroughs. Fourth, collaboration among researchers, designers, manufacturers, and users is vital. Zhao urged the industry to adopt a global perspective, noting that China's current petrochemical projects are at their peak, offering a rare opportunity for localization. However, this also means tight deadlines and high stakes. Failure to meet these challenges could jeopardize project implementation. He called for increased awareness and investment in R&D, as many companies remain unaware of the technological gaps compared to global competitors. The industry is currently caught in a cycle of low-price competition, harming product quality and overall development. Investment in R&D remains insufficient, and intellectual property disputes with foreign countries are increasing. Zhao urged the industry to boost R&D spending, not only in equipment but also in advanced technology and information systems. Without cutting-edge technology, there can be no world-class equipment. Additionally, under globalization, tracking and absorbing foreign advancements in technology, management, and patents is essential for industry growth. Finally, Zhao stressed the need for supportive policies. While company efforts are important, they must be backed by effective policy frameworks. Under the planned economy, financial and resource management was rigid and impractical in today’s market-driven environment. There is a need for innovation in management systems. Furthermore, past policies were often vague and lacked coherence, and future reforms should address these shortcomings to ensure sustainable development.

Track Accessories

In the mechanical field, tracking and positioning accessories focus on equipment status monitoring, location tracking, and operation and maintenance assistance, suitable for industrial machinery, engineering machinery, precision instruments, and other scenarios. Here are the main categories:

  • Mechanical position trackers: Equipped with dual-mode GPS and Beidou positioning modules, and housed in robust enclosures (shockproof, waterproof, and resistant to high and low temperatures), they can be directly installed on construction machinery (such as excavators, cranes) or mobile equipment. They transmit real-time location information, support geo-fence alarms, and prevent equipment theft or off-limit operations.
  • Vibration and displacement sensors: Using high-precision accelerometers and displacement meters, they monitor the vibration frequency, amplitude, and displacement of mechanical components (e.g., bearings, guide rails, drive shafts). Data is wirelessly transmitted to terminals to determine whether the equipment is operating normally and to early warn of potential faults (such as imbalance or looseness).
  • Robotic arm path trackers: Integrated with optical encoders or laser ranging modules, installed at the joints of robotic arms, they record real-time motion angles, displacement distances, and path trajectories of each axis. By comparing with preset programs, they ensure operational accuracy (e.g., controlling path deviations within millimeters during welding or assembly).
  • Hydraulic/pneumatic pipeline tracking accessories: Including flow sensors and pressure transmitters, connected in series in mechanical hydraulic or pneumatic pipelines, they track the flow rate, pressure change curves of media, and combined with temperature sensors, judge whether the pipeline is blocked or leaking, or the working status of components such as hydraulic pumps and cylinders.
  • Wireless data acquisition terminals: Acting as the "hub" of mechanical tracking, they receive data from various sensors (location, vibration, pressure, etc.) and upload it to cloud platforms via 4G/5G or LoRa wireless communication. They support historical data storage and retrieval, providing data support for mechanical maintenance and working condition analysis.

These accessories, ranging from macro-location to micro-status, enable full-life-cycle tracking and monitoring of machinery, improving equipment operation and maintenance efficiency and safety.
