SS Membrane Housing

Stainless Steel Membrane Housing - China Factory Direct Supplier (CE Certified)

This 4-inch SS Membrane Housing is a hot-selling product. The membrane housing is an indispensable component of the RO system. Its length matches the number of RO membranes. The product is polished inside and outside, beautiful and practical, and the working pressure meets the operating requirements of the RO system. RO membrane housings are widely used in industrial water treatment, wastewater treatment, and fluid separation processes, and can work under high pressure. The membrane housing has high corrosion resistance and is easy to install and disassemble.

Why Choose Our SS Membrane Housing?

✅ Corrosion-Resistant Material

We use 304/316L food-grade stainless steel (customizable), with a 2mm-thick shell. Tested in 5% salt spray for 1000 hours with no rust or pitting (vs. industry avg 500 hours), ideal for seawater/chemical filtration.

✅ High-Pressure Leak-Proof Design

Featuring a double O-ring seal and threaded cap, our housings withstand 150-300PSI pressure (2-4x higher than plastic housings). Lab tested: 0 leakage after 10,000 pressure cycles (vs. 5,000 cycles for competitors).

✅ Compatible with Most RO Membranes

Designed for 10-400GPD RO membranes (1.8"/2.5"/4" diameter). Includes adapter kits for 2.5"→4" membrane upgrades (free with orders ≥500pcs).

Differences between seamed and seamless in SS membrane housing

"Has seams/seamed" and "seamless" in SS membrane housing refer to the manufacturing method and structural design of the membrane housing, and the specific meanings are as follows:
"Has seams" means that the RO membrane housing is assembled from multiple parts, usually with seams formed by welding or other connection methods. These seams may have a certain risk of leakage and may require more attention when cleaning. Membrane housings with seams may be more competitive in manufacturing costs, but may require more maintenance and attention in long-term use.

"Seamless" means the RO membrane housing is manufactured through a one-piece molding process without obvious seams or joints. This seamless design helps reduce the risk of leakage and improves the strength and durability of the structure. Seamless membrane housings are generally easier to clean because there are no seams or cracks to hide dirt or bacteria. But at the same time, it costs more than seamless membrane housings.

FAQ

Is your SS membrane housing resistant to chemical corrosion?

A: Yes. We use 304/316L stainless steel (316L for extreme corrosion). Tested in 5% HCl solution for 500 hours with no material degradation, suitable for chemical industry filtration.

Will the housing leak under high pressure?

A: No. Our double O-ring seal and threaded cap design ensure 0 leakage even at 300PSI. Lab-tested: 10,000 pressure cycles (from 0 to max pressure) with no seal failure.

What's the difference between 304 and 316L stainless steel housings?

A: 304 is cost-effective for general use (e.g., household RO systems); 316L has higher nickel/molybdenum content, ideal for seawater or chemical filtration (e.g., pharmaceutical industry).

Can I get a sample before placing a large order?

A: Yes! We offer sample orders (5-10pcs) at 120% of bulk price. Samples include test reports (pressure resistance, material certification).
