8-inch side-contact FRP reverse osmosis membrane housing – specially designed for high-pressure seawater desalination – flexible piping – industrial-grade membrane pressure housing

8-inch side-connected fiberglass reinforced plastic (FRP) RO membrane housing is made of high-performance glass fiber reinforced plastic (FRP), renowned for its excellent high-pressure resistance and corrosion resistance. Its distinctive side-port design arranges the inlet and outlet interfaces of raw water and concentrated water on the side of the cylinder, providing system engineers with extremely high freedom and flexibility in pipeline layout, especially facilitating the parallel installation and maintenance of multiple membrane housings. The working pressure range of the housing covers an extremely wide range from 300 PSI to 2000 PSI, compatible with 1 to 8 8-inch membrane elements. It is an ideal pressure vessel for industrial-level applications such as large-scale brackish water and seawater desalination, difficult wastewater treatment, chemical material separation, etc., which require complex piping and high system reliability.

【Product Overview】
This product is an 8-inch side-port type glass fiber reinforced plastic (FRP) reverse osmosis (RO) membrane housing, specially designed for large-scale industrial reverse osmosis and seawater desalination systems. It is a high-performance and high-pressure core pressure vessel with excellent reliability. The unique side-connected design allows the inlet and outlet interfaces for raw water and concentrated water to be located on the side of the cylinder, providing great flexibility and convenience for the parallel installation of multiple membrane housings and the complex layout of system pipelines. The shell is made of high-strength FRP缠绕 and can withstand 1 to 8 standard 8-inch RO or nanofiltration membrane elements， offering a wide range of pressure grades from conventional 300 PSI to industrial-grade 2000 PSI， to meet the various demanding application requirements ranging from brackish water desalination to high-pressure seawater desalination.
【Product Features and Advantages】
Flexible and efficient pipe layout: The side-branch design enables the main pipeline to be centrally connected from the side, significantly simplifying the piping system when multiple membrane shells are connected in parallel. It saves installation space and is convenient for future maintenance and inspection.
Ultra-high pressure options available: We offer models with a pressure of up to 2000 PSI. These are specifically designed for high-pressure applications such as seawater desalination and high-salinity feedwater, demonstrating outstanding pressure resistance reliability and system adaptability.
Industrial-grade reliability: Composed of FRP material and stainless steel alloy components, it features extremely strong corrosion resistance, high-pressure tolerance and fatigue resistance, ensuring a long service life under harsh water conditions and continuous operation.
Easy maintenance: The structure design takes into account both strength and maintainability. The end cover can be opened relatively easily, facilitating the insertion, inspection and regular replacement of the membrane elements.
Model series completeness: Covers a wide range of models from conventional pressure to ultra-high pressure, and from single-chamber to multi-chamber membrane elements, providing customers with flexible selection options for precisely matching system designs.
【Typical Application Scenarios】
The core membrane stacks of large-scale seawater desalination plants and brackish water desalination devices.
Large-scale industrial wastewater zero discharge and reuse systems in industries such as power, chemical engineering, and metallurgy.
The pre-treatment reverse osmosis unit for the preparation system of ultra-pure water required by the electronics and pharmaceutical industries.
Municipal wastewater deep treatment and reclaimed water reuse project.
Other areas of liquid separation that require high flow rate, high desalination rate and flexible system layout.
