Sulfuric Acid Resistance R4040 End Entry Membrane Housing For Seawater Desalination

Sulfuric Acid Resistance R4040 End Entry Membrane Housing For SWRO

RO (Reverse Osmosis) Membrane FRP Pressure Vessels

Wuxi Fenigal Science and Technology Co., Ltd. Co., Ltd. has been supplying RO FRP pressure vessels for water industry products since 2010. After more than ten years of development, our factory now has several self-developed multi-axis rotating wire winding machines, which greatly improve the strength and surface flatness of the products, and has established five self-developed curing systems, grinding systems and pressure testing systems. At present, our factory produces 100,000 FRP membrane shells annually, meeting the needs of domestic and foreign customers with reliable products and perfect services.

Our Mission

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

To ensure product quality, we have established a scientific and perfect quality assurance system; from design and development to after-sales service, we use a rigorous professional attitude to integrate quality assurance into every process to provide customers with reliable performance and superior quality products.

Standard production procedure of RO pressure vessel

Winding → Sanding → Lathing → Drilling → Hydro test → Painting → Package

Standard inspection and test plan of RO pressure vessel

Our pressure vessels will be inspected in accordance with industrial standards.

The main inspection content of production includes items as follows:

1. The raw materials of production

1) Fiberglass

2) Epoxy Resin

3) Anhydride

2. The process test of production

3. Hydro-static pressure test (every vessel)

Increase the pressure at a constant speed, maintain 3 minutes and test at 1.1 times working

pressure , then make sure there is not any leak and the pressure gauge always keeps

original pressure

4. 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.
