Cylindrical Composite Stainless Steel Bolted Storage Tanks for Waste Water
Product Overview
Cylindrical composite stainless steel bolted storage tanks represent engineering excellence in modern wastewater infrastructure. These tanks provide superior solutions for municipalities and industries dealing with corrosive effluents, space constraints, and regulatory requirements.
Why Choose Composite Stainless Steel Bolted Tanks
Traditional concrete or single-layer steel tanks often fail under aggressive wastewater conditions due to:
- Chemical Corrosion: Sulfides, chlorides, and acidic compounds degrade materials
- Structural Fatigue: Thermal expansion/contraction cycles weaken welded joints
- High Maintenance: Frequent repairs increase downtime and costs
Composite stainless steel bolted tanks address these challenges through:
Three-Layer Construction
- Outer Layer: Aluminum alloy
- Base Material: Q355 carbon steel for cost-effective construction
- Inner Layer: Grade 304/316L stainless steel panels with bolt-fastened seams
Modular Assembly
Panels are prefabricated and bolted on-site, reducing installation time by 40-60% compared to welded tanks.

Applications in Wastewater Treatment
- Municipal Sewage Plants: Store sludge, stormwater, or treated effluent. Withstand hydrogen sulfide (H₂S) concentrations up to 500 ppm
- Industrial Facilities: Chemical processing plants (pharmaceutical, petrochemical) and food/beverage wastewater with high organic loads
- Mining Operations: Acid mine drainage (AMD) containment with pH ≤2
Case Study: Textile Plant in India
A textile factory in Gujarat replaced corroded concrete tanks with cylindrical composite stainless steel bolted tanks. Results after 3 years:
- Chemical Savings: Reduced neutralization agents by 70% due to zero leaks
- ROI: Achieved in 4 years through lowered maintenance and EPA penalty avoidance
Frequently Asked Questions
Can these tanks handle high-temperature wastewater (＞60°C)?
Yes. Specify inner liners made of SS304 or SS316L, which tolerate temperatures up to 80°C.
How are seismic loads managed in bolted designs?
Panels are engineered with flexible joints and reinforced base rings to absorb ground motion. Compliance with ASCE/SEI 7-22 standards is mandatory in earthquake zones.
What is the maximum diameter achievable?
Standard tanks range from 10-100 ft (3-30m). Custom designs can exceed 150 ft (45m) with auxiliary support structures.
Are disassembly and relocation possible?
Yes. Bolted tanks can be dismantled and reassembled at new sites, unlike welded or concrete structures.
