The FRP reverse osmosis membrane housing is a composite pressure vessel manufactured from fiberglass and epoxy resin using a precision winding process; it serves as the core pressure-bearing component of reverse osmosis membrane systems. These housings feature lightweight yet high-strength construction, excellent corrosion resistance, and a long service life. They are available in 4-inch and 8-inch diameters with pressure ratings ranging from 300 PSI to 2000 PSI, and are compatible with mainstream international membrane elements.FRP reverse osmosis membrane housings are widely used in water treatment sectors such as seawater desalination, industrial pure water production, and municipal water supply.

Pictures and Descriptions of the Winding Machine
Equipped with dedicated control‑software, the system configures parameters for winding‑length and fiber‑layers at both ends of the pressure‑vessel so as to control wall‑thickness. It ensures consistent dimensions and uniform wall‑thickness of end sections, effectively improves forming precision and provides outstanding pressure‑bearing performance for finished products.

FAQ
Q: In which fields are FRP reverse osmosis membrane housings primarily used?
A: They are primarily used in water treatment projects-including seawater desalination, industrial pure water production, municipal water supply, reclaimed water reuse, and ultrapure water production-serving as an essential pressure-bearing shell for reverse osmosis (RO) membrane systems.
Q: What precautions should be taken during installation?
A: Ensure reliable sealing at the connections between the membrane housing and the piping by using the appropriate sealing rings and fasteners. The side ports and end ports must align with the system's piping design. It is recommended to conduct a hydrostatic pressure test before initial use to verify there are no leaks.
Q: How can I determine if an FRP reverse osmosis membrane housing needs replacement?
A: Regularly inspect the housing surface; prompt replacement is recommended if cracks, bulges, severe scratches, or signs of leakage are detected. Under normal operating conditions, FRP membrane housings have a service life of 15 to 20 years and require minimal routine maintenance.
