🛢️ Description
LIDA offers a choice of Stainless Steel 304/316 bolted tanks to meet a variety of project requirements.
Stainless steel is an iron-based alloy containing more than 12% chromium and is resistant to corrosion by atmospheric and liquid media, it is widely used in the fields of food, medicine and water treatment.
Stainless steel comes in two grades: SS304 and SS316. Stainless steel 304 is suitable for general drinking water in most inland areas. For coastal areas with high salt spray or highly corrosive water, it is recommended to use 316L stainless steel containing molybdenum, which can improve corrosion resistance by more than 50%.
Through its innovative use of standardized prefabrication and bolted connections, SS bolted tank perfectly combines the superior performance of stainless steel with the engineering advantages of rapid deployment, flexibility, and ease of maintenance, providing a highly attractive solution for industries with high requirements for hygiene, timeliness, flexibility, and life cycle costs.
✅ Advantages of Stainless Steel Bolted Tanks for Drinking Water Storage
Stainless steel bolted tanks are made of SS304/316L panel and self-locked bolts, sealants, stiffener etc. They are now widely recognized as an ideal solution for drinking water storage.
🧪 Hygienic & Safe
Made of food-grade stainless steel with no coating, no heavy metal precipitation, and fully compliant with national drinking water standards. The smooth, dense surface inhibits bacteria and algae growth, maintaining excellent water quality.
🛡️ Excellent Corrosion Resistance
Highly resistant to corrosion, chlorinated water, and mild chemicals. No risk of coating peeling or rust contamination, ensuring long-term safe storage of drinking water.
✨ Smooth Inner Surface, Anti-Fouling
The polished interior is not prone to scaling or sediment attachment, greatly reducing cleaning and maintenance frequency while avoiding dead water zones.
⚡ Fast Installation & High Reliability
Factory-prefabricated panels enable quick bolted assembly on site, shortening construction period. The structured design delivers strong seismic and hydraulic performance, ensuring stable operation.
♻️ Long Service Life & Eco-Friendly
Service life exceeds 30 years with low maintenance cost. Stainless steel is 100% recyclable, non-polluting, and fully meets green water supply requirements.
🌍 Application
SS304 portable water storage tank: D4.29m × H7.25m, Volume: 100m³
📍 Location: Paraguay
SS316 drinking water storage tank with stand: D3.82m × H2.82m, Volume: 29m³ | D4.58m × H6.6m, Volume: 100m³
📍 Location: Cook Islands
💡
Design Requirements: The Cook Islands are located in the South Pacific Ocean, in the heart of Polynesia, which belongs to a typical tropical rainforest climate. To meet the challenge of high-salt-spray marine environment and wind speeds of 67m/s, SS316 material is required.
❓ Frequently Asked Questions
Q What is the difference between SS304 and SS316 stainless steel bolted tanks?
SS304 is suitable for general drinking water storage in most inland areas. SS316 (specifically 316L) contains molybdenum, which enhances corrosion resistance by more than 50%, making it the preferred choice for coastal environments with high salt spray or highly corrosive water conditions.
Q Are stainless steel bolted tanks safe for drinking water storage?
Yes. These tanks are made from food-grade stainless steel with no internal coating, eliminating any risk of heavy metal precipitation or chemical contamination. They fully comply with national drinking water standards and are widely used in municipal water supply projects worldwide.
Q How long is the service life of a stainless steel bolted tank?
The service life of a stainless steel bolted tank typically exceeds 30 years under normal operating conditions. The material requires minimal maintenance and is 100% recyclable at the end of its service life, making it a cost-effective and eco-friendly long-term investment.
Q How fast can a stainless steel bolted tank be installed on site?
Thanks to factory-prefabricated standardized panels and a bolted connection system, installation on site is significantly faster compared to traditional welded tanks. The modular design allows for quick assembly, reducing construction time and minimizing disruption to project schedules.
Q Can stainless steel bolted tanks be used in harsh marine or tropical environments?
Yes. For challenging environments such as coastal or island locations with high salt spray and strong winds, SS316L stainless steel tanks are specifically recommended. As demonstrated in the Cook Islands project, SS316 tanks are engineered to withstand wind speeds up to 67m/s and highly corrosive marine conditions.
Q What tank sizes and capacities are available for stainless steel bolted tanks?
Stainless steel bolted tanks are available in a wide range of sizes and capacities to suit different project requirements. For example, available configurations include tanks from 29m³ (D3.82m × H2.82m) up to 100m³ (D4.29m × H7.25m) and beyond. Custom dimensions can be designed to meet specific volume, space, and structural requirements.
