Product Overview
The Stainless Steel RO Membrane Housing is a critical component for reverse osmosis (RO) systems, designed to protect and secure RO membrane elements in water treatment processes. Made from SUS304 seamless stainless steel, our membrane housings ensure durability, corrosion resistance, and long-term reliability in various applications, including industrial water purification, seawater desalination, wastewater treatment, and the production of drinking water.
With precise polishing (mirror-finished inner/outer surfaces) and strict pressure testing (up to 25kg), our housings meet international standards for safety and performance. We offer flexible customization for inlet/outlet types, end caps, and lengths to match your specific RO system requirements.

Key Features
Premium Material & Craftsmanship
- SUS304 Stainless Steel: Ensures excellent corrosion resistance, ideal for harsh water environments (e.g., high salinity, chemicals).
- Seamless/Seamed Options: Seamless tubes (drawn from forging billets) for 25kg high-pressure systems; seamed tubes (automatic welding) for standard 16kg applications-both with uniform wall thickness to prevent leakage.
- Mirror Polishing: Inner/outer surfaces are polished to a mirror finish, reducing friction and preventing membrane fouling.
Superior Sealing & Durability
- Dual Sealing Design: ABS end caps with silicone O-rings for airtight sealing, ensuring no water leakage and extending membrane lifespan.
- Pressure Tested: 100% factory-tested at 16kg (seamed) or 25kg (seamless) to guarantee operating safety.
Flexible Customization
- Inlet/Outlet Options: End inlet/outlet or side inlet/outlet to fit system layouts.
- Connection Sizes: 6 points x 4 points, 4 points x 4 points, or custom specifications.
- End Cap Materials: ABS (cost-effective) or stainless steel (for extreme conditions).

FAQ
What is the difference between seamed and seamless membrane housings?
A: Seamed housings are welded and suitable for standard pressure (16kg) applications, while seamless housings (drawn from solid billets) handle higher pressure (25kg) and are ideal for large-scale systems.
Can I customize the length of the membrane housing?
A: Yes! We offer custom lengths to match the number of RO membrane elements (e.g., 2-core, 4-core). Contact our team with your system specs for a tailored solution.
What is the warranty for your stainless steel RO housings?
A: We provide a 5-year warranty against material defects and workmanship issues. Our after-sales team offers 24/7 technical support for installation and maintenance.
Do you provide installation guides or drawings?
A: Yes, we include detailed installation manuals and CAD drawings with every order to ensure easy setup.
