Ultimate Guide to SS Membrane HSG: Stainless Steel Membrane Housing, Price, Types, and Industrial Applications

Introduction to SS Membrane HSG

The demand for strong and long-lasting membrane housings has increased dramatically due to the rising use of RO water purification systems across domestic, commercial, and industrial sectors. One of the most essential components of any RO plant is the SS Membrane HSG, popularly known as SS membrane housing or stainless steel membrane housing.

These membrane housings are specifically designed to withstand high pressure, temperature variations, and continuous operation, ensuring the RO membrane inside operates smoothly without any leakage or operational failure. Because of their durability, performance reliability, and corrosion resistance, stainless steel membrane housings have become the top choice for many water treatment facilities.

This comprehensive guide explores everything about SS Membrane Housing, including its structure, applications, price, types, installation, advantages, and maintenance requirements.

Meaning of SS Membrane Housing

An SS membrane housing is a cylindrical stainless steel tube that holds an RO membrane. It provides pressure protection, structural support, and a controlled environment for RO water purification. The membrane inside the housing performs filtration, removing salts, chemicals, bacteria, and contaminants.

The housing ensures:

• Correct water pressure distribution

• Long-term protection of the membrane

• Leak-free operation

• Easy installation and maintenance

Why Stainless Steel Membrane Housings Are Preferred

Steel membrane housings offer superior:

• Strength

• Corrosion resistance

• Chemical compatibility

• Pressure handling

This makes them ideal for high-flow, high-pressure industrial RO systems where safety and durability cannot be compromised.

Structure and Design of SS Membrane Housing

The design of membrane housing stainless models depends on capacity, pressure rating, and application type.

Body Material and Thickness

Stainless steel housings are available in:

• SS304

• SS316

The wall thickness provides structural integrity under pressures of 300–1200 PSI or more.

End Caps and Clamps

The ends are sealed with:

• High-strength clamps

• Reinforced end caps

• Industrial-grade O-rings

High-Pressure Rating

Industrial stainless steel membrane housings provide exceptional tolerance for continuous operation under pressure.
