Product Introduction
Stainless steel perforated filter tube is a perforated metal pipe made by punching uniform holes on seamless or welded stainless steel tubes. It is widely used as filter support core, base pipe and pre-filter element. The orderly perforations allow fluid to pass through while holding back large particles. It can work alone or as an inner support for filter mesh, sintered filter and wedge wire screen.
Properties
Excellent corrosion resistance, high structural strength, pressure resistance, high temperature tolerance, clean and non-toxic, easy to clean and backwash, reusable.
Features
1. Consistent hole layout, stable flow distribution
2. Strong tube body, not easy to deform under high pressure
3. Smooth surface, no burrs after deburring
4. Can be matched with outer mesh or wedge wire screen as support pipe
5. Multiple end connection types for easy installation
6. Good resistance to acid, alkali and salt liquid
7. Cleanable and reusable, long service life
8. Custom perforation pattern and opening rate for different flow demands
Application Scenarios
Water treatment, oil well sand control, chemical filtration, food and beverage processing, pharmaceutical liquid filtration, wastewater treatment, resin trap, ion exchange, pipeline pre-filter, gas separation, mining slurry filtration.

We keep stable delivery cycle and can arrange production to match your project schedule.
Customer Feedback
Many filter manufacturers tell us the tubes are straight and holes are evenly arranged, which fits their outer screen perfectly.
Customers for water treatment projects say the tubes are easy to backwash and keep good performance after long running time.
Oil and chemical buyers comment the 316L and duplex versions hold up well in corrosive liquid without rusting.
Most clients mention the cut ends are clean without sharp burrs, saving extra work during their secondary assembly.
FAQ
Q1: Can I customize the hole size and perforation rate?
A1: Yes. We design the punching pattern according to your filtration requirement.
Q2: What material should I choose for corrosive liquid?
A2: 316L is for general acid and salt environment. 2205 or 2507 duplex steel is recommended for strong corrosion conditions.
Q3: What is the maximum length you can make?
A3: The standard max length is 6 meters. Longer tubes can be made by flange connection.
Q4: Can you make threaded or flange ends?
A4: Sure. We support different end connections including thread, flange, welded nipple and end cap.
Q5: Are samples available?
A5: Samples can be prepared. Sample cost and freight will be discussed separately.
Q6: What is your delivery time?
A6: Normal orders take 7–15 days, depends on order quantity and processing complexity.
