Introduction to stainless steel screen tube types and uses

Stainless steel screen tube, also known as water filter tube, is a filter device widely used in many fields. The following is a detailed introduction to stainless steel screen tubes:

Stainless steel screens are also known as slot screens, sewage treatment filter cartridges, Johnson screens, wedge wire stainless steel screens, etc.

1. Definition and classification

Stainless steel screen tube is a tubular filter element made of stainless steel material. Special stainless steel wires or strips are usually fixed on the support structure through welding and other processes to form a tubular structure with filtering function. According to their structures and uses, stainless steel screen tubes can be divided into many types, such as Johnson screen wedge wire stainless steel screen tubes, trapezoidal wire stainless steel screen tubes, etc.

2. Specifications and materials

Stainless steel screens come in a variety of specifications and materials to meet the needs of different fields and scenarios. Generally speaking, its specifications can range from Ф3.0mm to 450.0mm, and the materials include SUS310S, SUS316, 316L, 304, 304L, 321, 303, 303CU, 301, 202, 201 and other stainless steel materials. In addition, other suitable materials can be selected for processing according to customer needs.

3. Features and performance

Strong corrosion resistance: The stainless steel material makes the screen tube have good corrosion resistance and can be used for a long time in harsh environments such as moisture, acid and alkali without rusting.

High filtration efficiency: Stainless steel screen tubes have high porosity and filtration area, which can effectively filter out impurities and particles in the water and improve water quality.

Strong pressure-bearing capacity: The screen tube has a reasonable structural design and can withstand large water pressure and mechanical pressure, ensuring that it will not deform or break during use.

Easy to maintain: The stainless steel screen has a smooth surface with no edges, no burrs, and even gaps, making it easy to clean and maintain.

4. Application fields: The application fields of stainless steel screen tubes are very wide, mainly including the following aspects:

Water resource filtration: In the fields of water wells, water treatment equipment, environmental protection, water and domestic water desalination, stainless steel screens are used as filtration devices to remove impurities and particulate matter in the water and improve water quality.

Petroleum industry: In the process of oil extraction and processing, stainless steel screens are used as filtering devices to remove impurities and particulate matter in crude oil and protect subsequent equipment from wear and blockage.

Chemical industry: In chemical production, stainless steel screens are used as filtration devices to remove impurities and particles in solutions and ensure the quality and purity of products.

Other fields: Stainless steel screens can also be used in the recovery and filtration of alcohol and other organic solutions, agricultural irrigation, sewage treatment and other fields.
