Wuxi Fenigal Science and Technology Co., Ltd. has been supplying RO FRP pressure vessels for water industry products since 2010. After over ten years of development, the factory owns self-developed multi-axis rotating wire winding machines, which greatly enhance product strength and surface flatness, and has established five self-developed curing, grinding and pressure testing systems. Currently, it produces 100,000 FRP membrane shells annually, satisfying domestic and foreign customers with reliable products and perfect services.

Our Mission

Provide high-quality products to meet the personalized needs of customers

To guarantee product quality, a scientific and perfect quality assurance system has been set up; from design and development to after-sales service, quality assurance is integrated into every process with a rigorous professional attitude, offering customers products with reliable performance and superior quality.

Standard production procedure of RO pressure vessel: Winding → Sanding → Lathing → Drilling → Hydro test → Painting → Package

Standard inspection and test plan of RO pressure vessel: The pressure vessels are inspected in line with industrial standards. The main inspection contents in production include:

1. Production raw materials:

2. Fiberglass

3. Epoxy Resin

4. Anhydride

5. Production process test

6. Hydro-static pressure test (every vessel): Increase pressure at a constant speed, maintain for 3 minutes at 1.1 times working pressure, ensuring no leakage and the pressure gauge remains at the original pressure

7. Final Inspection

Application fields: Electronics, electricity, metallurgy, chemical industry, medicine, food and beverage, industrial sewage and wastewater, water reuse, brackish water, sub-seawater, seawater desalination and other fields.
