Stainless Steel 304 316L 4040 4021 SS RO Membrane Housing

Stainless steel membrane housings are essential components in reverse osmosis (RO) systems, providing a durable and corrosion-resistant environment for membrane filtration. The choice of stainless steel grade is crucial, as it influences the housing’s performance, longevity, and suitability for various applications. The models 304, 316L, 4040, and 4021 each have distinct properties catering to specific needs in water treatment processes.
Material Specifications:
304 Stainless Steel:
Composition: Contains 18% chromium and 8% nickel, offering good corrosion resistance and weldability.
Applications: Suitable for general water treatment applications, food processing, and less corrosive environments.
Features: Offers a balance of toughness and resistance to oxidation and atmospheric corrosion.
316L Stainless Steel:
Composition: An improved version of 304, with added molybdenum (2-3%), enhancing its resistance to pitting and crevice corrosion.
Applications: Ideal for marine environments, chemical processing, and pharmaceutical industries where exposure to harsh chemicals is common.
Features: Excellent durability, heat resistance, and non-reactive properties, making it suitable for high-purity applications.
4040 Configuration:
Size: The 4040 designation typically refers to the dimensions of the membrane (4 inches in diameter and 40 inches in length).
Applications: Commonly used in commercial and industrial RO systems, providing efficient filtration for larger volumes of water.
Features: Optimized design for space efficiency and compatibility with standard RO membranes, ensuring effective operation.
4021 Configuration:
Size: Similar to the 4040 model but with a different length, the 4021 is designed to accommodate specific system requirements.
Applications: Often used in specialized applications that require a compact design without compromising performance.
Features: Tailored for versatility, this configuration allows for easy integration into existing systems.
