Large FRP Storage Tank

Yingnai Large FRP Storage Tanks are designed for high-volume storage of chemicals, water, wastewater and other compatible process liquids. Field winding and modular fabrication allow large capacities with corrosion-resistant, lightweight construction. Diameter, height, resin system, structural laminate, roof, nozzles, platforms and access arrangements can be engineered to match site conditions and operating requirements.

Specification of FRP Storage Tank

ItemLarge FRP VesselSelection / Engineering Note
Product NameLarge FRP Storage VesselCustom corrosion-resistant storage equipment
Typical Capacity Range150–2500 m³Other dimensions can be engineered
Typical Diameter RangeD 4500–15000 mmOther dimensions can be engineered
Main Sizing DimensionCylindrical shell height HSee the three sizing-matrix sheets
Installation OrientationVertical, aboveground, generally field-fabricatedInstallation method depends on site and transport limits
Fabrication MethodOn-site filament winding or sectional field assemblySelected according to diameter, capacity and access
Structural ConfigurationInner corrosion barrier, structural shell, external protection and local reinforcementLaminate schedule is project-specific
Resin OptionsGenerally isophthalic or vinyl ester systems for industrial chemical serviceFinal resin must be checked against medium, concentration and temperature
ReinforcementSurface veil, mat and continuous winding reinforcement; local FRP stiffeners as requiredGlass type and content follow the laminate design
Design PressureAtmospheric as standardPressure or vacuum service requires a separate verified design
Operating TemperatureDesigned according to resin system, medium and actual service conditionsDo not publish a single universal temperature limit without resin verification
Operating MediumBulk storage of water, wastewater, acids, alkalis, salts and industrial process liquidsChemical compatibility review is required
Design Specific GravityProject-specific; hydrostatic load governs shell and foundation designCustomer should provide normal and maximum density
Corrosion BarrierResin-rich inner surface with chemical-resistant veil and laminateBarrier thickness and resin are selected for the medium
External ProtectionUV-resistant outer layer and optional fire-retardant/weathering systemColour and protection system can be customized
Tank Bottom / SupportsFlat continuous bottom on reinforced concrete foundation or ring foundationFoundation reactions must be confirmed by final design
Inlet and OutletLarge nozzles, drains and process connections customizedPiping loads should not be transferred directly to the shell
ManholeMultiple roof or shell manholes availableAccess and maintenance requirements govern arrangement
Vent / OverflowVent, overflow and emergency relief arrangement as requiredSizing follows filling, emptying and process conditions
Optional AccessoriesRoof, ladder, platform, guardrail, mixer support, level system and internal componentsAccessory loads must be included in structural design
Inspection and TestingSame, plus field-joint inspection and site hydrostatic testing where specifiedTest scope follows contract and applicable code
Applicable ReferencesASME RTP-1 and project/local structural requirements where specifiedReference does not imply certification unless contractually stated
Installation MethodOn-site winding or sectional assembly on prepared foundationInstallation manual and lifting plan should be project-specific
Application FieldsLarge-volume chemical, water, wastewater, food, fermentation and bulk process storageActual suitability depends on medium and hygiene requirements
CustomizationDiameter, height, roof, foundation interface, nozzle arrangement, platform and site-fabrication planManufacture according to approved drawings
Required Inquiry DataMedium, capacity, density, wind/seismic data, site access, foundation and nozzle scheduleThese inputs are required before final quotation and design
