The stainless steel filter is a type of metal porous filter element made from industrial metal powder, typically 304 or 316L. The raw material is formed through cold isostatic pressing and then sintered under high temperature and high vacuum conditions. The resulting filter element contains countless micropores that are curved, criss-crossed, and highly precise, allowing for deep-level precision filtration through pressurization.

The stainless steel filter is a highly advanced type of metal porous filter element that is widely used across many industries, including petrochemical, coal chemical, pharmaceutical, water treatment, food, metallurgical, and gas purification industries.

Products Applications

With its unique porous technology, stainless steel filters are widely used across a range of industries, including the petrochemical, coal chemical, pharmaceutical, water treatment, food, metallurgical, and gas purification fields. The filter is a new type of filtration and separation technology material that can be used for various applications, such as terminal filtration of petroleum products, fly ash filtration in the coal chemical industry, impurity removal and filtration of raw materials in the pharmaceutical and chemical industry, water purification, and filtration after ozone sterilization in the water treatment industry, and clarification and filtration of milk, beverages, beer, mineral water, and vegetable oil in the food industry.

Products Processing

The production process of stainless steel filters involves monitoring all raw materials, including the metallurgical composition, particle size distribution, and bulk ratio of the metal powder. After being formed through cold isostatic pressing, the filter is sintered at high temperature and high vacuum. Before and after the sintering operation, the carbon content is detected, and each batch of products produced is tested for bubble point, hardness of the medium, and permeability, density, and carbon content of the diameter of spherical particles to ensure high-quality production. The filter is also easy to weld, with seamless welding lengths of up to 1500mm.
