There are many types of high pressure rotary filter, mainly including steel filter, stainless steel filter and cast iron filter. These filters have their own characteristics and application scenarios to meet the needs of different industrial applications. The following is the specific introduction:
1. Steel filter of high pressure rotary filter
(1) Carbon steel filter
Carbon steel filters are usually made of carbon steel material, which has a higher strength and can withstand greater pressure, so it is often used in high-pressure environments. The cost of carbon steel filters is relatively low, but it is important to note that carbon steel is susceptible to corrosion, so it is more suitable when dealing with less corrosive fluids.
(2) alloy steel filter
Alloy steel filters use alloy steel materials, such as stainless steel, which not only have high strength, but also have good corrosion resistance. This makes alloy steel filters ideal for handling more aggressive fluids, especially in chemical and Marine applications.
2. Stainless steel filter of high pressure rotary filter
(1) 304 stainless steel filter
304 stainless steel is one of the most commonly used stainless steel materials, with good corrosion resistance and formability. Suitable for filtration of corrosive fluids in general, such as water treatment in the food and beverage industry.
(2) 316 stainless steel filter
316 stainless steel is more excellent than 304 in terms of corrosion resistance, especially the resistance to chloride is stronger. This makes it the material of choice for handling more demanding chemical fluids and Marine environments.
3. Cast iron filter of high pressure rotary filter
(1) Gray cast iron filter
Gray cast iron filters are commonly used in low and medium pressure applications, where they have some mechanical strength and good corrosion resistance. The cost of gray cast iron filters is relatively low and suitable for general industrial and municipal applications.
(2) ductile iron filter
Ductile iron filter has high strength and toughness, can withstand high pressure. They also have better corrosion resistance than gray cast iron and are suitable for more demanding industrial environments.
To sum up, the types of these high-pressure rotary filters have their own characteristics, and choosing the right filter type is crucial to ensure the effective operation of the system and extend the service life of the filter. In the selection, the nature of the fluid, working pressure, temperature and the requirements for corrosion resistance of the material should be considered.
