The Sintered Powder Metal Filters

sintered disc filters consist of highly uniform, interconnected networks of pores with tortuous paths that trap solid particles in gas or liquid. Excellent depth filters with superior mechanical strength. Stainless Steel Type 316L withstands temperatures up to 750F (399C) in oxidizing and 900F (482C) in reducing environments. These filters can be cleaned by other methods, such as ultrasonic baths or reverse flow flushing. If your application requires even greater resistance to corrosion, temperature, wear, and vibration, other nickel-based alloys are available.

The sintered powder metal filter is made of metal powder pressed through a mold and then sintered at a high temperature. It has the advantages of high mechanical strength, high-temperature resistance, good corrosion resistance, uniform pore size distribution, good air permeability, cleanable regeneration, welding, machining, etc.
The sintered powder metal filters are widely used in gas-liquid filtration and separation in the fields of the chemical industry, medicine, beverage, food, metallurgy, petroleum, environmental protection and fermentation, dust removal, sterilization, and oil mist removal of various gases and steam; gas buffer, etc.

Metal powder serves as the only raw material for the sintered metal powder filter; no binders are used. It is generated by cold isostatic pressing and then sinters at high temperatures. By adjusting the process parameters and metal powder particle size, the pore size and distribution of the component can be changed. Utilize the pore structure, material composition, compressive strength and other characteristics of different filter materials to develop filter products suitable for users.

Features
Strong resistance to corrosion
An inert metal with exceptional corrosion resistance is titanium. Strong alkali and strong acid media can be filtered using the titanium metal rod filter element. It has a wide range of applications in the chemical industry and in the filtering of the pharmaceutical industry's organic lysozyme production process.
Good tolerance to high temperatures
The titanium filter element has a high temperature resistance that goes up to 300C. In operational situations with high temperatures, this function is frequently used. The temperature resistance of the filter element made of polymer materials is normally limited to 50 C. The support and filter membranes will alter if the temperature goes beyond 50 C. It is frequently employed in the filtration of high-temperature liquids and steam filtration (steam filtration in fermentation processes), despite having a significant accuracy variance.
Superior mechanical qualities
With external pressure of 20 kg and internal pressure of 10 kg of destructive force, the titanium rod filter element has strong mechanical qualities and may be utilized in high pressure and quick filtration processes. The pore size of other polymer filter components will fluctuate or even break down when the external pressure is more than 0.5 MPa.
Good regeneration
Due to its superior corrosion resistance, high temperature resistance, and high strength performance, titanium rod filters have a good regeneration effect. There are two types of regeneration: chemical regeneration and physical regeneration treatment.
Physical regeneration method:
(1) Pure water recoil
(2) Steam blowback
(3) Ultrasonic cleaning
Chemical treatment method:
(1) Alkaline washing
(2) pickling

Product Introduction

The Porous Powder Metal SS 316L Cap-type Filter is a type of metal porous filter that is made from stainless steel 304, 304L, 316, or 316L powder. The filter is produced using a process that involves sizing, molding, and the raw materials. The use of stainless steel in the filter´s construction results in it being referred to as a stainless steel powder filter element.

In addition to the cap-type filter, the Porous Powder Metal SS 316L Filter can be manufactured as tube-type and plate-type filters. These filters are extensively used in several industries, such as medical, chemical, and metallurgical industries, as well as in gas purification applications. This is due to their excellent permeability, filter fitness, and high stock utilization.

The filter´s good permeability allows for the smooth flow of fluids or gases through it, while its filter fitness ensures that it can effectively remove contaminants and impurities from the fluid or gas passing through it. The filter´s high stock utilization results in it being able to operate for an extended period before needing replacement, making it cost-effective for industrial applications.
