Why is stainless steel preferred for screen filters in strainers?

What is a perforated tube?

Stainless steel is widely preferred for screen filters in strainers for several reasons related to its unique combination of properties that are especially beneficial in filtration applications. Here are the main reasons why stainless steel is often the material of choice:

Corrosion Resistance: One of the most significant advantages of stainless steel is its resistance to corrosion. This makes it ideal for use in a variety of liquids, including water, chemicals, and even corrosive substances. The chromium present in stainless steel reacts with oxygen to form a passive layer of chromium oxide on the surface, which acts as a shield against corrosion.

Durability & Strength: Stainless steel possesses high tensile strength, making it durable and resistant to physical stresses. In a filtration context, this ensures the screen can withstand pressure differentials and heavy loads of trapped particles.


Temperature Resistance: Stainless steel can withstand both high and low temperatures. This makes it suitable for applications where the fluid being filtered may be at elevated or reduced temperatures.

Non-Reactivity: For industries like food processing or pharmaceuticals, it's crucial that the filter material doesn't react with the product. Stainless steel is non-reactive with most substances, making it safe for such applications.


Hygiene: Stainless steel is easy to clean and does not harbor bacteria, making it a hygienic choice for industries like food and beverage or pharmaceuticals.


Versatility: Different grades of stainless steel cater to different environments and chemical interactions. For example, type 316 stainless steel, which includes molybdenum, offers higher resistance to chlorides like sea water.


Cost-Effective in the Long Run: While the initial cost of stainless steel might be higher than some other materials, its durability and extended lifespan mean reduced replacement and maintenance costs over time.


Appearance: In some applications, the aesthetics of the equipment are essential. Stainless steel has a clean and modern appearance, which can be an added benefit in certain settings.


Environmental Impact: Stainless steel is 100% recyclable. Its long life span and the possibility of recycling make it an environmentally friendly choice.


Given these benefits, it's clear why stainless steel is a top choice for screen filters in strainers. However, it's also important to select the appropriate grade and type of stainless steel depending on the specific application and environmental conditions.
