High-Strength Filtration · Stainless Steel Screen Pipe,A Core Component for Industrial Fluid Filtration

The stainless steel screen pipe is a high-strength filtration component manufactured from high-quality stainless steel plates or tubes through stamping, weaving, and welding processes. It offers key advantages such as high filtration accuracy, strong load-bearing capacity, excellent corrosion resistance, and long service life. The pipe is widely used in fluid filtration and solid-liquid separation applications in industries including petroleum, chemical processing, mining, water treatment, and environmental protection.

Its primary advantage lies in its high structural strength. Compared with ordinary filter pipes, its pressure resistance is increased by more than 60%, allowing it to withstand high-pressure conditions (≤20 MPa) without deformation or damage. In addition, the filtration holes are evenly distributed, with a filtration accuracy error of ≤±2%, effectively intercepting solid impurities in fluids and ensuring stable filtration efficiency. The smooth surface of the pipe body prevents scaling, making cleaning and maintenance convenient and significantly reducing operating costs.

Applicable Scenarios

The stainless steel screen pipe meets fluid filtration and solid-liquid separation needs across multiple industries. Core applications include:
Petroleum: Sand control filtration in oil wells, crude oil filtration, and oil pipeline filtration, effectively preventing sand particles from entering equipment and causing wear or blockages.
Chemical: Filtration of chemical media, catalyst recovery, and process fluid purification, ensuring stable operation.
Mining: Ore pulp filtration, tailings treatment, and groundwater extraction filtration, intercepting ore particles and impurities.
Water Treatment: Tap water filtration, industrial wastewater treatment, and seawater desalination pretreatment, removing suspended solids and impurities.
Environmental Protection: Waste gas treatment and waste residue filtration.
The product can be integrated with various equipment such as filters, filter tanks, and pipelines, accurately meeting the filtration and separation requirements under different working conditions.

Material Selection and Standards Compliance

Materials are selected for complex working conditions and comply with international industry standards. The main materials used are 304, 316, and 316L stainless steel.
304 stainless steel: Suitable for conventional room-temperature and neutral fluid conditions, offering excellent corrosion resistance.
316/316L stainless steel: Optimized for strong acid, strong alkali, high salt, and high-temperature conditions, significantly improving corrosion and heat resistance. Suitable for temperatures ranging from -40 °C to 650 °C, making it ideal for corrosive and high-temperature fluid filtration applications.
The production process strictly follows ISO 9001 quality management system, ASTM A312, GB/T 13296, and other international and domestic standards. Key indicators-including material composition, filtration accuracy, compressive strength, and corrosion resistance-are tested and certified by authoritative third-party organizations, ensuring stable and reliable product quality. The products can be exported worldwide.
