FRP Alkali Storage Tank
Our FRP tanks provide superior protection against strong alkalis like NaOH, offering a lightweight, durable, and leak-proof solution. As a leading manufacturer, our core strength is full customization. We tailor every detail—from resin chemistry (including PVDF liners for extreme conditions) to dimensions, structure (vertical/horizontal), and fittings—to perfectly match your unique operational and spatial requirements. Backed by rigorous ISO quality control, we deliver high-performance, non-standard solutions that ensure long-term reliability and cost-efficiency.
Product Introduction
FAQ

玻璃钢碱性罐_01

描述_01Fiberglass Reinforced Plastic (FRP) Alkali Storage Tanks are corrosion-resistant liquid storage vessels molded using CNC filament winding technology, with alkali-resistant resin as the matrix and glass fiber as the reinforcing material. Specifically designed for strong alkaline media such as Sodium Hydroxide (Caustic Soda) and Sodium Hypochlorite, these tanks offer superior advantages including high strength-to-weight ratio, impermeability, and durability. The core value lies in our ability to provide deep customization to meet the stringent storage requirements of the chemical, environmental, and metallurgical industries. As a professional manufacturer, our full-process customization capabilities cover every aspect from material selection to after-sales support, delivering a storage solution tailored exclusively for you.

Our Customization Capabilities:

1. Precision Customization for Media & Working Conditions

Media-Specific Formulas:Based on the type of alkali (NaOH, KOH, etc.), concentration, temperature, and impurities, we tailor the resin matrix and liner. For example, PVDF liners are used for highly concentrated or high-temperature alkalis.

Comprehensive Engineering: We optimize wall thickness and rib layouts through mechanical calculations based on pressure, vacuum, temperature differences, wind loads, and seismic intensity to ensure stability under extreme conditions.


2. Full Non-Standard Customization of Structure & Dimensions

Structural Forms:Vertical (flat/cone bottom) or horizontal (round/elliptical bottom), open or sealed top designs to fit installation spaces and process needs.

Volumes & Sizes: Capacities ranging from 0.5m³ to 200m³, with inner diameters from DN600 to DN4000. Exact dimensions, heights, and support positions are adjustable to solve space constraints.

Interfaces & Accessories: Customized inlets/outlets, manholes, flanges (GB, ANSI, etc.), level gauges, ladders, railings, insulation/tracing, and mixing devices, perfectly matching your pipeline systems.


3. Material & Process Customization

Material Upgrades: Food-grade resins (for pharmaceutical/food), flame-retardant resins (for explosion-proof areas), and UV-resistant outer layers (for outdoor use) are available.

Hybrid Processes:Combining hand lay-up, spray-up, and CNC winding for complex or irregular shapes ensures both strength and impermeability.碱性储罐特性_01

Core Product Advantages:

1. Superior Alkali & Corrosion Resistance

Utilizes vinyl ester or epoxy resins with a liner resin content exceeding 90%, providing a dense, impermeable barrier.

Withstands pH levels from 1 to 14. For high-concentration (above 45%) or high-temperature scenarios, custom PVDF composite liners are available to completely eliminate leakage and corrosion.


2. Lightweight, High Strength & Easy Installation

Weighing only 1/4 to 1/5 of carbon steel but with a strength of 300-400 MPa.

Eliminates the need for heavy lifting equipment, reducing transportation and installation costs by over 30%. Ideal for indoor, outdoor, or space-constrained locations.


3. Structural Stability & Longevity

CNC filament winding ensures uniform wall thickness (error ≤ ±0.5mm)

A four-layer composite structure (inner liner, sub-inner layer, structural layer, outer protective layer) guarantees pressure resistance and anti-aging properties.

Boasts a service life of over 20 years with low lifecycle maintenance costs.


4. Safety & Compliance

Seamless one-piece molding. Double-layer structures with leak detection systems are optional.

Complies with strict standards (e.g., "FRP Chemical Equipment Design Regulations") and passes rigorous hydrostatic and leakage tests.
