A transnational high-speed railway project, required to traverse a high-altitude permafrost zone, placed stringent demands on the fatigue resistance and low-temperature toughness of the track connectors.
Solution:
Customized development of 60°C ultra-low-temperature tensile bolts, which passed simulated freeze-thaw cycle testing in the "Xintai" laboratory and exceeded national standards by 30%.
Laser scanning technology was used to recreate track nodes on a 1:1 basis, precisely matching special-shaped washers with embedded sleeves, with installation tolerances within 0.2mm.
IoT sensors were deployed to monitor bolt stress in real time, with data directly connected to a cloud-based management platform, enabling fastener health alerts along the entire line.
Results After the project opened, the fatigue life of the track connectors reached 2.5 times the design value. The project was certified as an "Innovative Technology Application Demonstration Project" by China Railway Corporation, and Tailian was named a "High-Speed Railway Core Supplier."
Seismic Connection System For Super-High-Rise Buildings
Background:
A 300-meter landmark skyscraper, required to withstand an 8-magnitude earthquake zone, placed extremely high demands on the seismic resistance of its structural components and construction efficiency.
Solution:
Developed a three-level seismic nut combination, which, after biaxial vibration table simulation testing, achieved a load capacity of 10.9.
Implemented an AR-assisted installation system, allowing on-site technicians to view 3D assembly instructions in real time through a head-mounted display, reducing single-node installation time by 40%.
Established a "One-Code" quality record, with each bolt linked to a construction video and inspection report, ensuring lifelong accountability.
Results The client commented, "The Tailian solution made complex node construction as precise as building blocks." The building was also awarded the "China Steel Structure Award."
Overseas Photovoltaic Power Station Mounting System
Background:
A 500MW photovoltaic project in Southeast Asia faces sea wind erosion and temperatures exceeding 50°C, thus requiring corrosion resistance and the ability to quickly deploy and install systems.
Solution:
Developed aluminum-magnesium-zinc-plated photovoltaic mounting bolts, which passed salt spray testing for over 4,200 hours and achieved marine-grade corrosion resistance.
Designed a modular quick-clamping system, increasing the average daily installation capacity of a single worker from 20 to 60 sets, reducing construction time by 50%. The system is equipped with intelligent inspection drones, which automatically scan support deformation data monthly, achieving a 98% early warning accuracy rate.
Results After grid connection, the power plant's power generation efficiency exceeded expectations by 15%,Thai Union Group has become the preferred supplier of new energy photovoltaic power generation components in Southeast Asia.
