    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.

    📍 Paraguay
    SS304 portable water storage tank: D4.29m × H7.25m, volume: 100m³
    Municipal Portable Water (4)
    📍 Cook Islands
    SS316 drinking water storage tank with stand: D3.82m × H2.82m, volume: 29m³ ; D4.58m × H6.6m, volume: 100m³
    📌 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 recommended choice for coastal or high-salt-spray environments and areas with highly corrosive water sources.
    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 the risk of heavy metal precipitation or chemical leaching. They fully comply with national and international drinking water standards and inhibit bacteria and algae growth due to their smooth, dense interior surface.
    Q
    How long is the service life of a stainless steel bolted tank?
    Stainless steel bolted tanks are designed for a service life exceeding 30 years. Their corrosion-resistant properties and durable bolted construction require minimal maintenance, resulting in low lifecycle costs compared to alternative tank materials.
    Q
    How quickly can a stainless steel bolted tank be installed on site?
    Because all panels are factory-prefabricated to precise dimensions, on-site assembly is fast and straightforward using bolted connections. This significantly shortens the construction period compared to traditional welded or concrete tanks, making them ideal for urgent or remote deployment scenarios.
    Q
    Can stainless steel bolted tanks be used in extreme weather or marine environments?
    Yes. SS316 stainless steel tanks are specifically engineered for high-salt-spray coastal and marine environments. As demonstrated in the Cook Islands project, these tanks are designed to withstand extreme wind speeds of up to 67m/s and tropical climate conditions, providing reliable performance in challenging locations.
    Q
    Are stainless steel bolted tanks environmentally friendly?
    Absolutely. Stainless steel is 100% recyclable and produces no harmful by-products during its service life. These tanks are non-polluting, meet green water supply requirements, and contribute to sustainable infrastructure development across municipal, industrial, and remote applications.
