Hoang Tam - Installation of 2 Units of 20m3 Oil Storage Tanks for the Deneast Project in Binh Duong by Partner Tetra Pak Vietnam 01/2020 is a significant milestone, demonstrating our capability to meet the most stringent international technical standards from global corporations. Combining precise workshop fabrication with professional on-site installation solutions in Binh Duong, Hoang Tam successfully delivered the project on schedule, ensuring absolute compliance with food safety hygiene requirements and outstanding mechanical durability.
Overview of the Deneast Binh Duong Project and Collaboration Background
The Deneast factory in Binh Duong is one of the leading large-scale, modern production facilities for dairy, dairy products, and beverages in the Southern region. To operate a continuous production system with high design capacity, the storage of raw materials such as edible oil requires a large-capacity, stable storage tank system that meets strict food safety and hygiene standards.
In this project, Tetra Pak Vietnam—a world-leading food processing and packaging solutions company—acted as the main technology contractor. With its global reputation, Tetra Pak applies extremely rigorous technical standards to all auxiliary equipment and storage tank systems. Selecting a subcontractor to fabricate storage tanks requires a comprehensive capability assessment, ranging from technical credentials and workshop facilities to real-world quality management systems.
Hoang Tam is proud to have passed the strict vetting processes to become the direct partner responsible for engineering consulting, detailed design, workshop fabrication, and on-site installation of two 20m3 oil storage tanks. The successful handover and acceptance in January 2020 affirmed Hoang Tam's integrated capability in providing comprehensive industrial mechanical solutions.
Technical Challenges and Quality Requirements for Edible Oil Storage Tanks
Storing edible oil on an industrial scale is not just about holding liquid; it directly impacts raw material quality preservation, oxidation prevention, temperature control, and cross-contamination prevention. Therefore, the design and fabrication of these two 20m3 tanks had to strictly comply with specialized technical standards:
- High-grade Materials of Construction: The entire tank body, bottom, and all components in direct contact with the internal medium must use high-quality SUS304 stainless steel with complete, clear CO/CQ certificates. This material provides maximum resistance to chemical corrosion from free fatty acids in the oil, ensuring no alteration to the physical and chemical properties of the stored material.
- Ultra-Smooth Surface Treatment: The internal surface roughness of the tank must reach Ra < 0.8 µm. This polishing standard completely eliminates micro-gaps, preventing stubborn oil residues from sticking, and facilitates automated CIP (Clean-in-Place) processes with chemicals and hot water.
- Durable Mechanical Structure: With a capacity of up to 20,000 liters per tank, the load pressure on the tank bottom and support legs is immense. Hoang Tam's engineers accurately calculated the plate thickness for the tank shell, designed an optimal conical bottom for complete discharge, and engineered robust tubular support legs with flexible leveling feet.
- Effective Thermal Insulation System: Edible oil can easily solidify or degrade in quality if the ambient temperature drops. Therefore, the tanks were designed with a high-density PU (Polyurethane) foam insulation layer, cladded with polished SUS304 stainless steel sheet to maintain stable oil temperature and save energy for the heating system.
- Sanitary Standard Accessories: The tank system integrates a full suite of modern auxiliary equipment including: continuous level sensors, PT100 temperature sensors, double-acting vacuum relief valves to prevent tank collapse from pressure differentials, pressure-tight manholes, and 360-degree rotating CIP spray balls for internal cleaning.
Hoang Tam's Comprehensive Project Execution Process
The success of the 2-unit 20m3 oil storage tank installation project in Binh Duong is the result of applying a closed-loop, professional service process from solution design to physical handover.
1. Engineering Consulting and Solution Design
Immediately after receiving the brief from partner Tetra Pak Vietnam, Hoang Tam's engineering department conducted an on-site survey at the Deneast Binh Duong factory. We thoroughly analyzed factors such as installation space, foundation load capacity, and the layout of the existing process piping connections.
Using specialized 3D mechanical design software such as SolidWorks and AutoCAD, our engineering team built detailed tank models and performed Finite Element Method (FEM) stress analysis to ensure the tanks would not deform under full-load pressure. The detailed design drawings were then submitted and received absolute approval from Tetra Pak’s technical experts.
2. Fabrication at Hoang Tam's Manufacturing Workshop
The fabrication process was carried out entirely at Hoang Tam's modern manufacturing facility in Le Minh Xuan Industrial Park, Ho Chi Minh City, under the close supervision of our Quality Assurance/Quality Control (QA/QC) department:
- Blanking and Shaping: High-power CNC Plasma and laser cutting machines were utilized to create parts with extreme dimensional accuracy (tolerances under 0.5mm). The tank shells were rolled evenly on a new-generation multi-roll hydraulic plate rolling machine.
- ASME-Standard High-Pressure Welding: This is the key stage determining the durability of the storage tanks. Hoang Tam boasts a team of internationally certified welders. We applied TIG (Tungsten Inert Gas) and semi-automatic welding with back-gas purging (Argon). This technique ensures uniform penetration, eliminates porosity, avoids weld blackening, and minimizes oxidation in the heat-affected zone.
- Surface Treatment and Passivation: After completing the raw mechanical assembly, the weld beads were ground flat and polished flush with the sheet metal surface. The entire tank was then cleaned and chemically passivated to restore the natural protective chromium oxide layer of the stainless steel, giving the tank absolute rust-proof capability.
- Pre-delivery Quality Testing: Both tanks underwent rigorous testing, including Dye Penetrant Testing on load-bearing welds and a 24-hour Hydrostatic Test to ensure zero micro-leaks before leaving the workshop.
3. Transportation, On-Site Installation, and Commissioning in Binh Duong
In January 2020, the transportation of the two oversized oil storage tanks from Hoang Tam's workshop in HCMC to the Deneast factory in Binh Duong was carried out using specialized heavy-haul transport vehicles. The entire tank bodies were wrapped in PE protective film to prevent scratches and securely fastened on trailers.
At the site, Hoang Tam's field engineers collaborated closely with the Deneast project management team and Tetra Pak's supervisory representatives to draft a detailed Method Statement, ensuring absolute Health, Safety, and Environment (HSE) compliance. Using high-capacity cranes, the two 20m3 oil storage tanks were lifted, positioned, and anchored precisely onto the prepared concrete foundations.
Leveling and vertical alignment processes were executed using digital levels and laser positioning tools, ensuring inclination tolerances were kept within extremely tight limits. Subsequently, the mechanical team proceeded to connect the sanitary process piping system, install control valves, integrate instrumentation, and wire the central control panel.
