This picture vividly demonstrates the standardized and modular design of the "Top Opening FRP Composite Tank Series" products. The five cylindrical tanks are arranged from left to right in decreasing size, forming a clear specification sequence, which intuitively reflects the capacity selection range of this series of products. All the tanks are made of translucent light-colored fiberglass-reinforced plastic (FRP) material, highlighting the material's lightweight, high strength, and corrosion resistance. The black edges at the top and bottom of the tanks (probably for reinforcement or sealing structures) form a simple visual contrast with the tank body. The opening design on the tank top is its core functional feature, facilitating material feeding, cleaning, or internal maintenance. The picture uses a pure white background and a neat vertical arrangement, with a clean and concise composition, without any text interference. It professionally highlights the unified structure, complete specifications, and strong practicality of this series of products, which are suitable for various water treatment or industrial scenarios requiring corrosion resistance storage or chemical reactions.

Product Description

“Head Opening” FRP Composite Tank Series is designed for convenient, leak-proof media loading in water treatment systems, available in 10″ to 16″ sizes (multiple models optional):

Head Opening Design: The tank head features a φ40mm opening, with the head opening component made of durable alloy ABS material. An integrated O-ring seal inside the loading port ensures reliable leak-proof performance.

User-Friendly Operation: This design simplifies media loading while saving time and effort, making daily operation more efficient.

Specifications & Dimensions: The series covers models with volumes ranging from 3.8L to 91.7L (1.0 to 50.6 gallons). Key parameters include a 2.5″ NPSM opening size, a φ40mm head diameter, and a PE round base for stable placement.

Durable Construction: Built with high-quality FRP materials, the tanks offer excellent structural stability, suitable for long-term use in various water treatment scenarios.

Ideal for both small-scale and medium-scale fluid processing applications, these tanks balance practicality, durability, and ease of use.
