Technical Specification 

Outstanding Key Features

1. Superior Corrosion Resistance of 304L Material

    

   Adopting AISI 304L low-carbon stainless steel, it delivers excellent intergranular corrosion resistance, especially outstanding anti-corrosion performance in the weld zone after on-site welding, with no post-weld heat treatment required. It effectively extends service life in water and weakly corrosive media, reducing replacement and maintenance costs for customers.
    
2. Full-Welded High-Strength Integrated Structure

    

   All intersection points of wedge wire and longitudinal support rods are fully welded by high-frequency resistance welding, with no loose points or deformation. It has strong resistance to high pressure, impact and vibration, maintaining long-term stable operation under harsh working conditions.
    
3. Unique V-Wire Self-Cleaning Anti-Clogging Design

    

   The trapezoidal wedge wire forms a continuous "outer narrow, inner wide" V-shaped filtration slot. Particles only form 2-point line contact with the slot edge, with no risk of embedding and jamming. It has excellent self-cleaning performance, is easy to backwash, and greatly reduces the frequency of shutdown cleaning and maintenance.
    
4. Precision Machined Welded Bevel End

    

   Pre-machined standard industrial V-type bevel ends with precise bevel angle and smooth groove surface, enabling rapid full-penetration on-site welding. It forms a zero-leakage integrated rigid connection with the pipeline system, no additional connecting parts required, with low installation cost and extremely high structural stability.
    
5. Ultra-High Filtration Precision & Flow Efficiency

    

   The filtration slot opening can be customized from 0.02mm to 5mm, with full-pipe slot tolerance controlled within ±0.025mm, achieving precise and stable interception to avoid sand running and material leakage. The maximum open flow area can reach 32%, 3-5 times higher than traditional slotted/perforated pipes, with low fluid resistance and large circulation capacity.
    
6. Full Customization Support

    

   We can fully customize the base pipe wall thickness, slot opening, single pipe length, bevel standard, material and other parameters according to the customer's actual working conditions, design pressure and filtration requirements, providing a perfectly matched solution without secondary modification.

Q1: What is the corrosion resistance of the 325mm 304L wire wrapped screen pipe?

A1: Made of AISI 304L low-carbon stainless steel, it has excellent intergranular corrosion resistance, especially in weld areas. It works well in fresh water, weak acid-alkali media and needs no post-weld heat treatment.

Q2: Is the welded bevel end of the 325mm screen pipe easy to install?

A2: Yes. The bevel end is pre-machined to industrial standards (30°-35° angle), enabling quick full-penetration on-site welding, no extra fittings needed.

Q3: Can the filtration slot of the 304L 325mm Johnson screen be customized?

A3: Absolutely. The default slot is 0.3mm, and it can be customized from 0.02mm to 5mm to match your particle interception needs.

Q4: What scenarios is the 325mm 304L welded screen suitable for?

A4: It is widely used for deep well drilling, municipal water supply, wastewater treatment, geothermal wells and industrial fluid filtration.

Q5: What is the maximum open flow area of this 304L wire wrapped screen?

A5: The maximum open flow area can reach up to 32%, which is much higher than traditional slotted pipes, ensuring low fluid resistance and high efficiency.
