Industrial and commercial fiberglass reinforced plastic pressure vessels, water treatment filter tanks/softening tanks, with multiple interface options available.
Standard glass reinforced plasticcomposite tank series are engineered for high-performance water treatment scenarios, integrating premium materials and rigorous quality standards to deliver reliability and safety:
Material Excellence: The tank liner uses food-grade HDPE, while the reinforcement layer adopts epoxy resin + fiberglass; thread/flange connections are made of high-quality composite materials, ensuring health, non-toxicity, and corrosion resistance.
Superior Durability: The tanks undergo strict fatigue tests (125/150 psi cyclic pressure, over 100,000 cycles) and burst pressure tests (4× the designed pressure), guaranteeing stable performance under high-load conditions.
Authoritative Certifications: The product has obtained NSF, ISO9001, ISO14001, CE certifications, as well as domestic hygiene license approval documents, meeting both international and domestic safety and quality standards.
Flexible Specifications: Available in diameters of 6"-8" (multiple models optional), with an operating temperature range of 1°C-49°C (34°F-120°F), adaptable to diverse application environments.
These tanks are ideal for industrial, civil, and commercial water treatment systems, balancing safety, durability, and adaptability.
Fatigue test > 100,000 times, burst pressure test (4 times), static pressure test (1.2 times)
Application fields
The filtration and softening processes in civil, commercial and industrial water treatment systems
[Product Overview]
The standard FRP composite tank series is a general-purpose pressure vessel made by combining a food-grade HDPE inner tank with an epoxy resin and glass fiber winding reinforcement layer. This series of products is renowned for its standardized design, high versatility, and outstanding reliability. The working pressure is available in two grades: 125 PSI and 150 PSI. It offers multiple connection options, including industrial threads, household threads, and flange connections. The products have passed authoritative certifications such as NSF, ISO9001, ISO14001, and CE, and have undergone more than 100,000 fatigue tests. They are core equipment for filtration, softening, and other processes in civil, commercial, and industrial water treatment systems.
