4 Types of Sintered Filters Used in High-Temperature and Pressure Conditions

The sintered metal filter is one of the safest ways to filter corrosive liquids and gases in a range of industries. Metal components are combined together through high temperatures to achieve desired porosity and create a finished product. Read on to know more about the types of sintered filters to make the best selection.

Filtration is a crucial aspect in everything we do, from drinking water to the gas used as a coolant in nuclear reactors and eliminating certain impurities from liquid and gases. You can’t always rely on the plastic filter, chalk, strainer, and standard filtration process. For a specific task, sintered metal filters are necessary for multiple purposes based on the micron of porousness.

In high-pressure situations, most filter elements are likely to fail. You can’t depend on plastic or paper in pressure-rich environments. That’s where sintered filters come to the rescue for filtration and purification of high-temperature liquids and gases. It offers significant advantages, such as corrosion resistance, better filtration, high thermal shock, toughness, and resistance to breakage, and reliable pressure of the fluid.

Let’s take a look at different types of sintered filters suitable for demanding operating conditions.

1.    Sintered Powder Metal Filter

Sintered powder metal filters are ideal for applications, in which high mechanical performance is necessary to maintain. Although it is less porous than stainless steel sintered fiber products, they are robust, durable, and best suited for harsh working conditions. Sintered powder filter elements include materials like stainless steel, bronze, nickel, titanium, etc.


·      High mechanical strength

·      Easy to clean and repeated use

·      Resistant to heat and corrosion

·      Easy fabrication

·      Long service life


2.    Sintered Metal Filter Tubes

Sintered metal porous tube filter elements are widely used in the chemical industry, electric power, pharmaceutical, machinery, food and beverage, and more. It offers high flow rates at the low-pressure drop with no chance of media migration.


·      High dirt holding capacity

·      Corrosion resistance

·      Wide operating temperature range

·      High strength


3.    Sintered Metal Filter Disc

This disc element is made using sintered wire mesh by using laser cutting in a vacuum environment at a very high temperature. Stainless steel wire mesh filter disc is quite popular, with its amazing dirt holding capacity, heat resistance, precision for various uses, and resistance to corrosion and abrasion.


·      Exclusive backwashing

·      Efficient and precise

·      Easy to operate and clean

·      Resistant to acid, alkali, corrosion, and abrasion

·      Great dirt holding capacity

·      High heat resistance


4.    Sintered Mesh Filter Sheet

It is made from 5 layers of sintered wire mesh, having a strong structure, accurate filter precision, and easy backwash cleaning. It is also resistant to corrosion, high temperature, and pressure. It is commonly used in pharmaceuticals, liquid and gas filtration, chemical processing, food and beverage, oil and gas filtration, polyester, and water treatment industries.


·      Withstand high temperature and pressure

·      Resist chemical reaction during the fluid process

·      Mechanically strong

·      Possibility to customize into various applications

·      Easy to punch, fabricate, shear, and weld

·      Fits different applications of varying filter rating requirements

·      Work under high pressure without any damage

·      Resistant to corrosion and abrasion


Industries require different types of materials and sintered filters depending on their working environment. You can opt for any kind of sintered metal filter to meet your specific needs and perform operations under high temperature and pressure without worrying about corrosion.

These sintered filters come in various shapes such as cylinders, discs, tubes, and cups, with a filtration rating of 5 microns to 300 microns to ensure excellent efficiency. You can go for sizes and shapes that suit your requirements and applications.
