Over the last decade, the adoption of Large Size Field Tanks has grown dramatically across global industries such as petrochemicals, mining, water treatment, and metallurgy. Driven by increasing energy demands, stricter environmental regulations (e.g., ISO 16961:2015; ANSI/NSF 61), and a surge in large-scale infrastructure projects, the global field tank market surpassed USD 4.2 Billion in 2023, with an expected CAGR of 7.1% through 2030 (MarketsandMarkets).

Key industry drivers include:

• Increased demand: Storage needs for chemicals, liquids, slurries, and hazardous materials are rising rapidly.
• Stringent safety & environmental standards: Compliance with ISO, ANSI, and FDA guidelines is non-negotiable for competitive suppliers.
• Longevity & maintenance: Modern Large Size Field Tanks offer 25+ years of service life with proper maintenance, minimizing TCO (Total Cost of Ownership).

Large Size Field Tanks are industrial-grade storage units designed for capacities from 100 m³ up to 50,000 m³ and beyond. They are engineered to withstand harsh chemical, thermal, and operational loads in continuous duty environments.

Industrial-grade Large Size Field Tanks combine advanced composite (FRP/GRP) and metallic (carbon/steel alloys) options to deliver optimal corrosion resistance, temperature durability, and mechanical performance tailored for application-specific environments.

• Material: High-performance vinyl ester resin (FRP tanks), 304/316L stainless steel, and alloy steel per application requirements.
• Manufacturing: Computerized winding/lamination (FRP), CNC plasma cutting, robotic arc welding, or manual assembly by certified welders (for metallic tanks).
• Testing: All Large Size Field Tanks undergo 100% hydrostatic and non-destructive testing per API 650/ISO 28765/EN 12285.
• Coatings: Epoxy/polyurea/special corrosion-resistant coatings or PE/ECTFE lining as specified.
• Certification: Full compliance with ISO, FDA (water/food), ANSI, and regional standards. Factory has ISO 9001:2015 and API Q1 certification.

• Petrochemical: Crude oil, diesel, gasoline, methanol, chemical reagent storage (API 650/620 adherence).
• Water & Wastewater: Raw water, demineralized water, industrial sewage, brine, or sludge handling (EN 12285, FDA-grade coatings).
• Mining & Metallurgy: Leachate, tailings, acid/alkaline solutions, process slurries (specialized lining for abrasion and corrosion).
• Food & Pharma: Vegetable oil, alcohol, syrup, food acid, and pharmaceutical intermediates (compliance with FDA, GB 9685).

Key Advantages:

• Unmatched Corrosion Resistance: FRP and alloy tanks resist over 120 aggressive chemicals (see Corrosionpedia).
• Extended Life-Cycle: 25–50 years with minimal maintenance free from rust or pitting – double the service life of traditional carbon steel solutions.
• Modular Construction: On-site assembly of large panels enables rapid installation and simplifies transport of even 40,000+ m³ tanks.
• Cost Efficiency: Lower TCO due to zero painting demand and reduced maintenance downtime.
• Regulatory Compliance: Built for ISO/EN/ANSI standards ensuring local and international project acceptance.

• Capacity & Geometry: From 500 m³ to 50,000 m³. Cylindrical, rectangular, or custom geometry.
• Location & Foundation: Tank base layout, seismic or wind loading, underground/aboveground options.
• Material Selection: FRP with specialty resins (bisphenol-A, vinyl ester), stainless (316L/2205), or hybrid (duallaminate).
• Internal Linings: Anticorrosion lining (ECTFE, epoxy, PE, glass flake) selected as per medium/temperature.
• Nozzle Configuration: Manholes, vent ports, instrument nozzles, custom pipe entry, overflow options.
• International Standards: Specify ISO, API, GB, ASTM as mandatory compliance.
• Ancillary Systems: Ladder, walkway, internal heating/cooling coil, insulation, anti-foam devices.
