R4040 End Entry FRP Membrane Housing - Customizable Multi-Pressure
Wuxi Fenigal Science and Technology Co., Ltd. has supplied RO FRP pressure vessels for the water industry since 2010. With over 10 years of development, it has self-developed multi-axis rotating wire winding machines (enhancing product strength and surface flatness) and five systems for curing, grinding, and pressure testing. Annually producing 100,000 FRP membrane shells, it serves domestic and foreign customers with reliable products and good services.
Our Mission
Provide high-quality products to meet customers' personalized needs
A scientific quality assurance system is established, integrating quality control into every process from design to after-sales, ensuring reliable and superior 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: Inspected per industrial standards, including raw materials (Fiberglass, Epoxy Resin, Anhydride), process tests, hydro-static tests (each vessel, 1.1 times working pressure for 3 minutes with no leakage), and final inspection.
Product features: Resistant to 25% sulfuric acid, 10% hydrofluoric acid; high temperature resistance up to 60/90°℃; fully adaptable to special media environments like strong acid, strong alkali, etc. Pressure level coverage: 300psi/450psi/600psi/800psi/1000psi/1200psi/1500psi.
