Common plate and frame materials for plate and frame oil purifier

Plate and frame oil filter is a common filtering equipment widely used in filtration and purification of lubricating, hydraulic, transformer, and other oils. The plate frame is one of the core components of the plate and frame oil filter, and its material directly affects the filtering effect, durability and application range of the equipment. The following is an introduction to the common plate and frame materials of the plate and frame oil filter:

1. Polypropylene (PP)

Features:

- Corrosion resistance: Good corrosion resistance to acids, alkalis and most chemicals.

- Lightweight: Lightweight, easy to operate and install.

- Low cost: Relatively low price, economical and practical.

Applicable scenarios:

- Suitable for filtering general industrial oils, such as lubricating, hydraulic, etc.

- Not suitable for high temperature or highly corrosive environments.

2. Stainless steel (such as 304, 316)

Features:

- High strength: High mechanical strength and good pressure resistance.

- Corrosion resistance: 304 stainless steel is suitable for general environments, 316 stainless steel has stronger corrosion resistance and is suitable for harsh environments.

- High-temperature resistance: can be used in high-temperature environments.

Applicable scenarios:

- Suitable for filtering high temperature, high pressure or highly corrosive oil, such as chemical industry, food industry, etc.

- Commonly used in high-precision filtering and long-term operation.

3. Cast iron

Features:

- High strength and wear resistance: high mechanical strength, suitable for high-pressure environment.

- Moderate cost: the price is between polypropylene and stainless steel.

- Heavyweight: the equipment is heavy, and it is inconvenient to move and install.

Applicable scenarios:

- Suitable for high pressure and large flow oil filtration, such as heavy machinery, mining equipment, etc.

- Not suitable for corrosive environment.

4. Aluminum alloy

Features:

- Lightweight: lightweight, easy to operate and install.

- Corrosion resistance: good corrosion resistance to general oil.

- Good thermal conductivity: suitable for occasions where rapid heat dissipation is required.

Applicable scenarios:

- Suitable for small and medium-sized oil filters, such as car repair, laboratories, etc.

- Not suitable for highly corrosive or high-temperature environments.

5. Composite materials

Features:

- High strength: Combining the advantages of multiple materials, it has high mechanical strength.

- Corrosion resistance: Depending on the composite material, the corrosion resistance varies.

- Lightweight: Lightweight and easy to operate.

Applicable scenarios:

- Suitable for oil filtration in special environments, such as aerospace, high-end manufacturing, etc.

- High cost, suitable for high-demand occasions.

6. Rubber-coated plate frame

Features:

- Good sealing: The rubber coating improves the sealing performance of the plate frame and prevents leakage.

- Corrosion resistance: The rubber coating has a certain corrosion resistance.

- Good elasticity: It can adapt to certain deformations and extend the service life.

Applicable scenarios:

- Suitable for occasions requiring high sealing, such as high-precision filtration, chemical industry, etc.

- Not suitable for high-temperature environments.

Summary

The selection of plate and frame materials for the plate and frame oil filter should be determined according to the specific application scenario, oil properties and working environment:

- Polypropylene (PP): economical and practical, suitable for general industrial oil filtration.

- Stainless steel: corrosion-resistant and high-temperature resistant, suitable for harsh environments and high-precision filtration.

- Cast iron: high strength and wear resistance, suitable for high pressure and large flow occasions.

- Aluminum alloy: lightweight, good thermal conductivity, suitable for small and medium-sized equipment.

- Composite materials: high performance, suitable for special environments and high-demand occasions.

- Rubber-coated plate frame: good sealing, suitable for high-precision filtration and chemical industry.

Selecting the right plate and frame material can improve the filtration efficiency of the oil filter, extend the life of the equipment, and reduce maintenance costs.
