Expanding Global Footprints: Zhongneng Huajian Successfully Delivers Precision Chemical Tank Clusters and Mega Thermal Storage Systems
As global industrial infrastructure trends toward higher automation and stricter environmental mandates, liquid containment engineering must evolve beyond simple storage. Modern processing facilities require integrated, thermodynamically stable, and highly anti-corrosive fluid matrices. Zhongneng Huajian (Shandong) Metal Structure Co., Ltd. continues to solidify its benchmark status as a state-owned holding EPC contractor by announcing the successful completion and operational handover of two heavy industrial fluid storage engineering projects: the Dana 1,500-ton high-tech chemical tank cluster and the Jilin Power 2,000m³ mega thermal storage water system.
Operating from our 15,000 square meter digitized production plant, our engineering division utilized advanced multi-axis stress simulation and automated dual-sided submerged arc welding (SAW) to deliver these customized structures under zero-defect quality parameters.
Project Profiles: Overcoming Complex Fluid Dynamics and Thermodynamic Stresses
Each industrial sector introduces unique chemical properties and thermal reactions that demand tailored metallurgical selections and welding configurations.
The Dana 1,500-Ton Scale Chemical Tank Cluster
Engineered for Guangdong Dana's new chemical materials facility, this project required the fabrication and assembly of a highly interconnected chemical tank grid. The stored media consisted of high-purity, volatile, and mildly aggressive chemical agents.
- Material & Surface Integrity: To prevent chemical product contamination and structural wall degradation, our technical division specified premium, low-carbon stainless steel (SS316L). The internal weld profiles underwent precise mechanical flush-grinding followed by automated chemical passivation to achieve an ultra-smooth finish, thoroughly eliminating microscopic crevices where corrosive agents could settle.
- Intelligent Pipe Matrices: The cluster integrates continuous pneumatic fluid-level transmitters, digital radar gauges, and automated vapor-recovery manifold loops designed to eliminate volatile organic compound (VOC) emissions during high-volume transfers.
The Jilin Power 2,000m³ Mega Thermal Storage Tank
Constructed for the Jilin Datang Thermal Power Plant, this 2,000 cubic meter vertical storage asset acts as a thermodynamic stabilization core for regional municipal heating distribution.
- Managing High Thermal Cycling: Operating under continuous water temperature fluctuations, the tank shell experiences repetitive thermal expansion and contraction cycles. Our structural engineering team utilized finite element analysis (FEA) to design variable-thickness shell course courses that safely distribute localized thermal stresses.
- High-Density Insulation Matrix: The structure features an external high-density polyurethane insulation jacket enveloped in an aluminum armor shell, restricting thermal loss to less than 0.5°C per 24 hours under extreme sub-zero ambient winter conditions.
Engineering Excellence: Advanced Non-Destructive Testing (NDT) Protocols
Precision Component Prep ➔ Automated Sync Assembly ➔ 100% NDT Verification ➔ Hydrostatic Stability Run
To validate the structural safety of these massive fluid containment installations before active commission, our Quality Assurance team executed rigorous structural audits on site.
- Comprehensive NDT Verification: 100% of the structural butt-welds on the Dana chemical tanks were subjected to internal radiographic testing (RT) and high-penetration ultrasonic testing (UT), ensuring zero micro-voids or lack-of-fusion tracking.
- Hydrostatic Stability Run: The Jilin 2,000m³ thermal tank completed a strict 48-hour continuous hydrostatic settlement audit. Digital laser telemeters monitored the concrete foundation pad at multiple coordinate nodes, ensuring perfectly uniform load distribution without structural deflection.
Technical FAQ Section
Q: How does Zhongneng Huajian prevent galvanic corrosion in stainless steel tank clusters?
A: Our 15,000㎡ plant isolates all stainless steel fabrication from carbon steel processing sectors. On-site assembly utilizes specialized non-ferrous handling tools, and all structural contact boundaries with carbon steel supports are isolated using heavy-duty PTFE isolation pads.
Q: Can your industrial fluid engineering systems integrate into pre-existing plant PLC controls?
A: Yes. All instrumentation arrays-including temperature sensors, pressure transmitters, and automated shut-off valves-utilize universal industrial protocols (such as Modbus or Profibus), allowing direct integration into a client's centralized SCADA system.
